The Legacy of Tea
Botanical names are always
complex. The full name of the tea plant is Camellia
sinensis. The term Sinensis is Latin for Chinese,
and the name was given because the first tea
plant was discovered in China.
The initial stages of tea cultivation are shrouded
by the mists and antiquity and entwined with
myth and legend. A medical book published in
the year 2737 BC had the following to say. “Tea
grows in winter in the valleys by the streams
and on the hills of Ichow, and does not perish
in severe winter. It is gathered on the third
day of the third month and then dried. It quenches
the thirst, it lessens the desire for sleep,
and it gladdens and cheers the heart.”
So tea from the earliest appearance imbued with
the aura of the Gods and celebrated as a combination
medicine and elixir.
After many centuries the properties of tea has
taken many dimensions. Tea today is regarded
the king and the commoner of all drinks. There
is more adventure and more ritual surrounding
the gathering of tea and it’s drinking
than there is for any other drink. Tea started
its career in the West as a favourite aristocrat.
It was rare and expensive, an extravagant delicacy.
Its costliness is evident from the rich silver
caddies that now fetch very high prices at auctions.
These were articles that every lady craved to
possess. To serve tea was to distribute generosity.
In fact tea became such a snob, so popular that
it necessitated the invention of a whole new
meal, so called “Afternoon Tea.”
Ladies used to visit each other to gossip over
a cup of tea. This prompted Henry Fielding to
sum up these times “Love and scandal are
the best sweeteners of tea.”
In its progress from fashionable aristocrat
to every day commoner, tea has still not lost
its intricacies of flavour, its refinement and
its fascinations. Sri Lankan wide range of teas,
the golden brews of the Bogo/Maskeliya teas,
the delicate bouquet of the Nuwara Eliya teas
and the pungent Uva teas when in season, all
these can be compared to vintage wines The tea
tasters on the other hand are as fastidious
as wine tasters capable of detecting almost
the hour of the morning the tea leaves were
plucked.
Just as some people choose wines to suit the
food they eat, there are teas to go well with
every mood and occasion. The all-embracing aspect
of tea is its central place it occupies in the
cultures of the countries that adopt it. Whether
at a Japanese tea ceremony, in a Bedouin tent,
or in an urban café partaking in a cup
of tea is an essential and characteristic part
is society’s life. Many others drink intoxicants,
but there is little impact on manners, on hospitality,
on the ways in which people come together and
drink together.
Many renewed tea drinkers have expressed the
view that the proper enjoyment of tea can only
be developed in an atmosphere of leisure, friendship
and sociability. It helps to win friends, and
the beverage symbolises communication, shared
moments, sympathy and harmony.
In modern Chinese homes tea is always served
to guests as a sign of friendship and hospitality,
and in restaurants a pot of tea is always the
first and the last thing to be brought to the
table.
General character
of the tea plant
Tea plant enjoys a very
vigorous growth, and is capable of flourishing
under extreme weather conditions. It is known
to have grown as far North as the province of
Georgia in Russia where the winters are long
and severe and snowfall is a daily occurrence.
In the Southern Hemisphere tea is grown in Natal
in South Africa where the conditions are not
so ideal for active growth. Conditions in Ceylon
fall in between and the North East and the South
West monsoon mostly influence the growth of
the tea bush.
Extreme weather conditions are not at all conducive
for growth. The general conditions that prevail
in the country are as follows.
a. The North East monsoon period. It lasts from
October to January. Rains are received mainly
in the North East and the Uva province.
b. An intermediary period that lasts from February
to March. This may be a dry period usually accompanied
by strong winds just before the period ends.
c. The South West monsoon period lasts from
April to July when abundant rain falls in South
West regions of the country.
d. Second intermediary period, lasts from August
to September.
It now becomes clear that the topography and
the monsoons play an important part in the propagation
of tea in the country. The average mean temperature
ranges from 79° F to 82° F in the low
country and 58° F to 75° F in the hill
country.
During the heavy cropping months of March, April
and May, general quality levels drop, but picks
up rapidly thereafter when the South West monsoon
blows dry. There is also less quality during
the wet period from November to January under
the influence of the North East monsoon. Tea
prefers a cool humid climate. It is observed
that a pleasant climate for man is not a good
climate for tea. Cool conditions at higher altitudes
could retard growth, but could produce a high
quality product.
It is established that in Ceylon, an acre of
tea in full production will draw from the soil
under normal weather conditions, about ten tons
of water per day. This calls for a rainfall
of about 0.1 inches per day. The entire husbandry
of any land depends on its topsoil. It must
at all times be well preserved from the wasting
influence of the sun, rain and wind.
Tea is a shade loving jungle plant, and under
normal conditions it grows best under a fair
canopy of forest trees. They should not however
be permitted to compete with tea for plant food.
For steady growth, it requires an average rainfall
of at least 100 inches. Its root system is mostly
in the top three feet of soil. Under very dry
conditions the plant could wilt and leaf production
can reduce drastically. It is best grown in
acid soils. The most common types are the Chinese,
Assam and Indo-China, but a vast variety exist
between them. .
Tea is a commercial commodity and is a product
of the Camellia Sinensis. It is a flowering
evergreen shrub, and grows freely in many tropical
and sub-tropical regions in the world. Today,
it forms a major industry in Ceylon, India,
Bangladesh, Kenya and Indonesia. It is also
grown extensively in many parts of East Africa.
Seed culture and
propagation
Originally, the selected
seeds were directly placed in the holes, but
later, nurseries in selected places were set
up for the purpose and later transplanted in
the holes. This gave an opportunity for the
discarding of unhealthy plants. This method
of propagation had been in vogue for a long
period of time, but within recent years, methods
of improving yields and type by "selection"
have engaged attention.
Today tea is propagated in a different manner,
known as "vegetative propagation."
What this means is that tea is grown from leaf
cuttings taken from selected mother bushes of
high yielding and disease resistant strain.
By this method uniformity of the desired characteristics
of tea could be achieved and maintained.
This practice had been in vogue in Japan way
back in the 1880's. This custom was generally
followed in India in the late 1930's, but it
took a longer time for it to be observed in
Ceylon. All cuttings from one bush whether of
the first or subsequent generations form what
is called a clone. All members of one clone
are of the same genetic composition and look
the same, which mean that their quality and
the cropping potential are the same as the mother
bush from which they originally descended.
Mother plants from which cuttings have to be
taken are specially treated. Today, science
has advanced to such an extent that it is now
possible to produce a "super tea plant"
that could grow with vigour, having the correct
form and capable of producing a large harvest
of high quality tea.
Another factor that has to be considered when
selecting mother plants is its longevity. In
a mixed stand, many tea bushes die each year.
By the fiftieth year, about half of the original
plants would have died which calls for replacements.
Many reasons could be attributed to such occurrences,
but some varieties could have a short natural
span.
Tea was originally propagated with seeds, with
the result; a vast variety of different types
of bushes can be seen on old tea plantation.
It has been proved beyond any reasonable doubt
that tea plants generated from seeds do not
produce progeny true to type bearing identical
characteristics of the parent seed bearer.
In the case of tea plants raised through clonal
propagation, all the attributes of the mother
tree are produced genetically. It is for this
reason that raising the offspring from seeds
have been dispensed with and research has proved
that plants grown through vegetative propagation
are best, provided sufficient care has been
taken in the selection of the mother bushes.
It should have the potency to produce flush
freely and have a natural resistance against
disease. It should have the capacity to withstand
drought and the ability to run a long cycle.
Before cuttings are taken from selected mother
bushes, nurseries to accommodate them should
be prepared well in advance. In selecting the
location, care should be taken to ensure that
there is sufficient supply of water within easy
distance. Acidic soils rich in humus are the
best, but water logged areas should be avoided.
The preparation of nursery beds is an all important
factor and should be carried out in a very prudent
manner.
The most suitable time for planting the cuttings
is at the commencement of the monsoon. The soft
and hard stems and those with damaged leaves
should be discarded. The selection of the cuttings
to be planted in the nurseries should be carried
out carefully, as the object of vegetative propagation
could be defeated if they do not root well in
the nurseries.
Adequate shade should be provided with ferns,
with regular light sprinkling of water. The
nurseries should be regularly weeded and fertilised.
After about a year in the nursery, they are
ready for planting in the fields, and this task
is usually undertaken during the commencement
of the rainy season.
A tea bush under forcing climates of the plains,
could be brought into production within two
and half to three years and fully developed
a few years later. Growth however could be retarded
in the hills where the seasonal changes are
more marked, and the period of growth in differing
altitudes and climates could vary considerably,
depending on the climatic conditions.
For commercial purposes the tea tree is grown
as a bush, but if left to grow wild it could
extend to a height of thirty feet and above.
Tea, which is grown from sea level to over seven
thousand feet is considered a hardy evergreen
plant. Its yields are high at tropical and sub-tropical
temperatures, but the finest teas are secured
from the slower, and consequently, smaller yielding
growths on the hills.
To maintain a continuous flush, the growth of
the plant is artificially retarded by regular
cutbacks. This helps to maintain the bush at
a height of about three feet, for convenience
of plucking. Pruning promotes growth during
the period of recovery, while the plant replaces
lost foliage. It is from the two leaves and
the unopened leaf that tea is produced. Pruning
promotes the growth of additional plucking points,
which in turn increases its yield.
Tea leaves are generally harvested by women
but men are used when the flush is on. Under
normal conditions a person could collect about
25 kilos of tea a day that could produce about
11 kilos of made tea. This amount could however
reduce drastically during the dry season. A
kilo of made tea may require about 6,000 shoots
of picked leaves, and this goes to prove that
labour costs make up a large proportion of the
cost of tea. It is for this reason that tea
cultivation has remained concentrated in the
third world countries.
Attempts to mechanise this operation has been
made in the state of Georgia in Russia with
a certain degree of success. Japanese has devised
cunning shears with pouches attached to the
blades enabling the user to collect about 275
kilos of tea a day. It has also been tried in
other countries including Ceylon. Unfortunately,
it is generally agreed that machines cannot
discriminate sufficiently to select the two
leaves and the bud, which is considered the
ideal for the manufacture of quality teas. Further,
the topography of the tea lands in our country
does not permit the free use of mechanical harvesters.
Tea is always plucked in the same manner by
removing the two leaves and the bud. In Ceylon
the tea flushes all the year round. Depending
on the monsoons, certain areas flush well during
certain periods of time. On average the first
four months of the year are considered the lean
period for crop. The four months that follow
are regarded the highest cropping months of
the year. September is again a low cropping
month, but a mini rush originates from October
and lasts until December. As a rule, the bulk
of the crop is harvested during the first six
months. Due to the vast changes in the weather
patterns in recent times, these old established
patterns of cropping are continuously changing.
Tea replaced coffee that was ravaged by the
coffee rust disease. The first commercial planting
of tea took place in the island in 1867. This
was undertaken on an abandoned coffee estate
in the Kandy district. The tea industry in the
country expanded before long, to become one
of the leading exporters to the world.
Today, there are 188,971 hectares under tea
cultivation, which represent about 3.8% of the
land area of Ceylon. This area is broadly subdivided
into four major climatic zones, where the agro-ecology
exerts a profound influence on the chemistry
on the tea plants, and on the tea.
First Commercial Tea Plot
“It
all started with a few tea seeds germinated
at Loolecondera”
It is here that we introduce
the person who, more than any other showed Ceylon
the way out of the coffee disaster by founding
an even greater plantation industry.
James Taylor was born in 1835 at Monboddo, Kincardineshire,
Scotland. He was one of a family of six children,
who was described by his schoolmaster as "a
quiet, steady going lad," His mother died
when he was nine years old. His father married
again, but James did not take kindly to his
stepmother. It must have been this setback that
prompted him to seek his fortunes in a strange
land at the tender age of sixteen.
At that time the owners of coffee plantations
were looking for "sons of soil" in
Scotland for their properties in Ceylon. In
1851, young James signed the form of engagement
to G. & L.A. Hadden the London agents for
Loolecondera estate. The contract was for three
years as assistant manager, for a salary of
pounds sterling 100 a year, from which he had
to pay his fare to Ceylon. On October 22nd he
set sail to Ceylon, never to return home again.
At twenty years he was made the manager of Loolecondera
responsible in all for about 1,100 acres.
The early proprietors of Loolecondera Plantation,
Hewaheta were G.D.B Harrison and W, M. Leake.
This property was subsequently sold to Anglo-Ceylon
and General Estates Company Limited. Its produce
in the early 1880's, came under the careful
management of James Taylor. His initial success
at Loolecondera was freely spoken about in planting
circles and the teas he produced acquired a
high reputation among Ceylon teas in London.
The first batch of tea manufactured on Loolecondera
was marketed in Kandy. A more scientific evaluation
of Leake's tea, along with other Ceylon Company's
teas was made in 1871. The result was most encouraging,
and the London Brokers did not hesitate to place
a valuation of 3 shillings 6 pence. This prompted
the owners to extend further cultivation of
tea with special attention being paid to its
manufacture. Taylor by then had mastered the
art of tea cultivation, but was not proficient
in the making of good tea.
A brief visit to India helped him to learn the
art of tea manufacture. He also had free access
to the expert knowledge of Jenkins, considered
a knowledgeable tea planter from Assam, who
was given charge of the Company's operations
in Ceylon. Jenkins provided all assistance to
Taylor, and above all, inspired confidence in
him. Before long, Taylor was able to produce
teas equal in all aspects to Assam teas.
The most interesting factor regarding the "original
tea plot" planted in 1867, was that the
first dose of fertiliser in the form of caster
cake was only administered in 1885, but production
figures indicated that the bushes were growing
vigorously and the yields had been maintained
at around 475 pounds of made tea per acre.
He died on the estate that he loved. His tombstone
at Mahaiyawa cemetery, Kandy, carries the following
inscription:
"In pious memory of James Taylor, Loolecondera
estate Ceylon, the pioneer of the tea and cinchona
enterprises, who died on May 2nd 1892, at the
age of 57."
Although James Taylor is remembered as the "father"
of Ceylon tea, we must not forget his many fellow
planters. They fought back from the coffee disaster
and brought a new industry in its place. To
them, it was all a part of their rugged outdoor
life. For their recreation they hunted the leopard,
the bear, wild pig, and other animals that roamed
the jungles surrounding their plantations.
Essential pre-requisites
for a tea estate
A well-found self-contained
tea estate forming an economical unit in Ceylon
must have a resident manager, a permanent resident
labour force, and a fully equipped factory with
ancillary plant and buildings. It should have
a good cover of tea interspersed with shade
trees, stone terraces to prevent soil erosion
and windbreakers to shield the tea fields from
monsoon winds.
A good system of roads, to provide easy access
to all parts of the estate is essential for
the transmission of green leaf to the factory.
Housing for the resident labour force, with
spare land for their own allotments, pasture
for their goats and cattle must also be provided.
Dispensary with qualified attendants within
the estate, for the treatment of their ailments
is desirable and schools for the education of
their children are a necessity.
Tea estates have been established in plains
and valleys, on steep hillsides, and on wide
high plateau. Within limits, the tea plant is
known to grow on soils of any texture, but jungle
land is considered best of all. Tea is considered
a wild plant, and the jungle provides a more
natural habitat that is usually rich in the
plant food which tea requires. On a broad generalisation,
it may be said that the best tea is usually
found on the more acid soils. Tea grows poorly
on neutral or alkaline soils. Climate however
plays an important part in the production of
quality teas.
An Efficient Labour
Force
An efficient staff and
a good and loyal labour force no doubt are a
real asset to an estate. On the superintendent
and his assistants' rests the responsibility
of management. We have no doubt acquired this
art of management from the Europeans that pioneered
this project in the country.
Social relationship between the management and
the labour class has changed considerably over
the years. The subordinate staff that usually
consists of clerks, storekeepers, tea-makers,
engine room attendants, dispensers etc. cannot
always be recruited locally. Today, an estate
will have a mixture of different nationalities
serving the same master. All these factors have
to be taken into account when dealing with the
labour force.
An Ideal Layout
The initial clearing of
land, and prior planting operations, form a
work of major importance upon which the success
of subsequent operations and the eventual prosperity
of the property are largely dependent. Clearing
of jungle land for tea is a major undertaking.
The undergrowth is first cleared, followed by
the cutting down of trees and other heavy growths,
after which the entire area is burnt. The heavy
timber is thereafter removed, but the ash and
other decaying matter left to provide the tea
plants the necessary nutrients.
The cleared land is then surveyed for drainage,
roads, building sites, and above all a convenient
location for the factory. It is only after all
these operations have been completed that the
planting operations start. The layout of the
estate for planting purposes is largely determined
by the lie of the land. The area to be planted
is then marked out for long lines of tea bushes
The arrangement of tea bushes in the field had
always been a hotly debated issue ever since
tea became a plantation industry in the mid
19th century. Tea plants used to be planted
either in squares, rectangles, or in triangular
fashion, so spaced as to allow for a full cover
of tea when the bushes are mature. The more
modern method adopted on slopes and hillsides
is "contour planting "where the lines
of tea bushes follow the contours of the land.
This system allows for a more economical distribution
of bushes, and is widely used in the country
today. According to this method about 7,000
to 12,000 plants could be planted in a hectare
of land.
Careful Pruning
If a tea plant is permitted
to grow freely, it could produce flowers and
fruits, but very few shoots to manufacture tea.
The young tea plant is frequently cut back to
a few inches from the ground to encourage lateral
growth, and thereafter it is pruned at intervals.
Pruning is done to prevent it from becoming
a tree. Regular pruning turns the plant into
a flat toped bush, of a size and shape usually
three to four feet in height, suitable for gathering
the leaf. A flat table facilitates the gathering
the leaf manually, or could be trained to accede
to mechanical harvesting. A well spread out
frame provides ground cover and prevents unnecessary
weed growth. Regular pruning helps to develop
a sturdy framework capable of supporting a profuse
growth in the future years. A well-trained tea
bush will assist in obtaining the highest possible
crop in the shortest possible time.
During the early stages, pruning was done mostly
to remove dead wood. The scientific aspect of
pruning has undergone radical changes over the
years before the modern systems were adopted.
Incorrect trimming down of tea bushes could
lead to heavy deaths. A close study of all phases
of pruning has been done today, and all stages
standardised.
Under normal circumstances, the tea bush becomes
unproductive of flush, and pruning is undertaken
at regular intervals to remove extra foliage
and over-matured wood, to develop a sturdy framework
that can sustain luxuriant vegetative growth,
and maintain it as a constant leaf producer.
As the age of pruning increases, shoots become
smaller, with the result increasing number of
banjhi shoots appear on the surface and the
flush decreases.
If the cutting back of the operations is delayed,
the plucking table continues to rise making
it difficult for tea pluckers to gather the
flush.
The pruning cycle may not conform to a set pattern
at different elevations. Growth is more vigorous
at lower elevations; with the result pruning
rounds is shorter and often undertaken every
fourth year. Growth is slow at higher elevations,
and this period could be extended further in
the up-country areas.
Pruning is carried out wherever tea is grown,
although the system may differ from district
to district. It is a skilful operation, and
carried out with a sharp and specially shaped
knife. It is an operation that calls for skill
and care. It has to be carried out in a manner
so as not to cause damage to the bush, as careless
handling could make them susceptible to pests
and diseases. The frequency and intensity of
pruning could differ at different elevations.
There is however, no set rule as to the periods
of pruning, but it is an accepted fact that
at higher elevation the intervals are longer
than in the low country.
Care of the soil
The nurturing of the tea
bush, and the cultivation of the soil on which
it grows, is an integral part of tea propagation.
In this regard, conservation of the soil, maintaining
a good ground cover, supplementing any deficiency
of plant food, providing humus and fostering
the health and the vigour of the bush, are just
a few of the guide lines for the planter to
follow.
Tea is usually grown on steep slopes, where
the heavy rainfall is experienced, where the
average varies from hundred inches in some districts
to over two hundred and fifty in others. These
factors have jointly contributed to one of the
greatest problems a planter is faced today.
Soil conservation has always been a problem
in the country, and it is been tackled in a
different manner today, as against the methods
adopted by the early pioneers. The practice
of clean weeding is fast giving way to selective
weeding. The more innocuous sorts are left behind
to bind the soil, and attention is now focused
on the question of a proper tea cover that could
eliminate weed growth.
Much topsoil has been lost over the years, and
this problem has reached critical proportions
today. Where clean weeding has to be resorted
to, proper drains, silt-pits, and terraces have
been constructed to prevent soil erosion. Today,
much attention is paid to planting shade trees
and nitrogen fixing shrubs in the tea to assist
towards the conservation of the soil.
Regular application of fertiliser, often chemical,
as against organic, is followed to maintain
the tea bush in a viable condition. The three
most important ingredients required for the
successful cultivation of tea are, nitrogen,
potash, and phosphoric acid. The ingredients
could be adjusted according to the deficiencies
or otherwise of this plant food in the soil.
Nitrogenous trees and plants also fulfil the
equally important function of providing shade,
binding the soil, and providing a rich humus.
In recent years, attention is paid to "composting"
as a means of making the maximum use of all
available green and bulk manure.
Gathering of Tea
is a Continuous Operation
The choice of good tea
land, the opening of an estate, the ensuring
growth, and care and cultivation of the bushes,
all lead up to one culminating purpose. It is
the continuous harvesting of the leaf from the
mature tea bushes that every planter looks forward
to.
It is considered a skilled and a fascinating
operation, and referred to as "plucking."
Tea is commercially manufactured from the "flush"
or the leaf-growth on the side branches and
the stems of the bush. Plucking the "two
leaves and the bud" is the common description
given to this operation. The bud is small and
unopened, and the two leaves are tender and
succulent.
At any altitude, the selection of leaf and the
style of plucking determine the quality of the
tea that could be manufactured in the factory.
Gathering just two leaves and the bud reflect
normal plucking, anything less would constitute
"fine” plucking, and the inclusion
of extra leaf or leaves constitute "coarse"
plucking. At lower elevations the tea bushes
throw out tender leaves faster than at higher
elevations, and the plucking intervals are determined
accordingly. In countries near the equator,
such as Ceylon, plucking is carried out all
the year round. In the colder regions tea harvesting
is seasonal.
Tea plucking is a highly skilled operation,
and is traditionally carried out by women. They
have acquired this skill of selecting the leaves
to be plucked, over the years. Their nimble
fingers are trained to break the tender leaves
and transfer them in handfuls into the baskets
they carry on the backs. All this is done at
an amazing speed. Mechanical plucking has been
tried before, but without much success.
At intervals, the baskets are taken to the roadside,
and the leaves carefully picked to eliminate
stalk and other extraneous matter before weighing.
The leaf is then transported to the factory
in the quickest possible time, in specially
built motor lorries. Aerial ropeways could still
be seen, in certain estates, performing this
task. It is with this carefully plucked tea
leaves that manufacture commences.
Preparation and Manufacture
Tea considered the most
popular beverage next to water, is made from
two leaves and the bud of the plant "Camellia
Sinensis". Even today, it has remained
a symbol of mystery, scientific challenge and
good taste. There are many ways, in which the
leaf may be prepared, but most teas are designated
green or black, the former unfermented, and
the latter fermented.
The process of tea manufacture has evolved through
ages and times, and distinguishing stages can
be recognised. The first was the hand process
used in China. The Dutch took teas of this vintage
to Europe in 1610. The second phase is attributed
to the Assam planters, who in 1839 used the
Assam variety of tea, and simplified the Chinese
method of hand preparation. The third phase
started with the introduction of machinery in
the early 1880's. Teas have now come to be manufactured
rather than prepared. The use of the tobacco
cutter, the crushing, tearing, and curling (CTC)
machine in tea manufacture, saw the dawn of
the fourth phase. The fifth is now being pursued
with both hot and cold water soluble instant
tea.
In Ceylon, the cultivation and manufacture of
tea, in a way is unique. At a time when dietetics
has almost become a science, when purity and
cleanliness in food and beverages were so strongly
insisted on -- Ceylon -- from the very inception
of tea manufacture, is well known to have paid
the greatest attention to ensure that the doubtful
nature of some of the early Chinese blends which
were consumed as tea, were completely eliminated.
Withering
This is the most important
process of tea manufacture. A careless wither
or an uneven one will not give good tea even
from the best type of leaf.
The leaf arriving at the factory is quickly
weighed and spread evenly in tats or troughs.
This is a process where the excess moisture
in the leaf is released to make it pliable for
the next process of rolling. Rollers compress
the leaf and help to extract the sap from the
leaves and initiates fermentation. A good wither
will prevent the leaf from breaking up, but
will impart a twist.
Liquors from fresh leaf are bitter, but in well-withered
leaf, sweetness develops. Process of withering
should not be hastened, and if the correct levels
are reached, the leaf when squeezed into a ball,
it will not open out. Under wet conditions,
the loss in weight of withered leaf should be
around 35% to 40%. Under dry conditions, the
loss could be around 45%.
The time required before the leaf reaches this
stage is dependent on temperature and humidity
and could range from 18 to 24 hours in different
seasons and districts. During the wet season
or in humid areas, optimum conditions are reproduced
artificially. Directing heated air through lofts
by means of fans does this. Withering in this
instance is a term of convenience rather than
of exact application.
During this process of withering, the leaf is
subjected to both physical and chemical changes.
This is a process that has to be carefully watched,
as uncontrolled withers could lead to the manufacture
of poor quality teas.
Rolling
After obtaining the correct
degree of wither, the leaf is rolled, twisted,
and at the same time, slowly broken up. The
leaf cells are ruptured in the process, and
their contents brought into contact with the
air to start the chemical reactions necessary
for the production of black tea. As soon as
the cells are ruptured, the enzymes in the leaf
come in contact with the oxygen of the air and
oxidisation necessary for the substances responsible
for flavour, colour, and aroma takes place.
Different rolling techniques are used to cater
to the needs of the trade. Disintegration of
the leaf is accompanied by heat development.
This has to be checked, as excessive heat is
detrimental to quality.
Rollers differ considerably in mechanical detail,
but not in principal. It consists of a circular
table with a hard surface on which brass or
wooden battens are fitted. Above it is an open
cylinder into which leaf is fed. As this cylinder
rotates, the amount of pressure imparted to
the leaf against the surface of the table could
be adjusted.
To obtain a good appearance of the final product,
rolling should be carried out without the application
of pressure. If on the other hand, the aim is
to be to obtain strong and coloury liquors,
hard rolling should be carried out to extract
the maximum sap from the leaf. During the quality
season, when dry conditions set in accompanied
with high winds, teas at higher elevations acquire
an essential oil inherent in the leaf to produce
flavour. Rolling has to be regulated so as to
preserve the oil in the leaf from escaping.
For the production of a large percentage of
small leaf grades, hard rolling is essential.
Roll-breaking
The next step, roll breaking,
though considered an unfortunate necessity,
has two objectives. To remove twisted leaf off
the rolled shoots that clogs and impedes circulation.
It also facilitates further twisting action
on the large leaf. It is also done to cool the
bulk of leaf when the temperature rises during
the process of rolling.
There is no standard form of roll breaking,
and altering the mesh sizes, adjusting the speed
of vibration, the amplitude of the vibration,
and the slope of the tray, could attain the
desired objectives.
Fermenting
The finer particles collected
after roll breaking, are fermented to bring
about the changes necessary to make a tea liquor
palatable. This process can only take place
when the cells of the tea leaf are properly
ruptured. The liquor of under-fermented tea
will taste raw and green, and that of an over-fermented
tea will come out soft. The degree of colour,
general level of quality and flavour could be
varied by adjusting the period of fermentation.
As this chemical process takes place, the colour
of the leaf changes from a greenish to a bright
coppery colour. The period of fermentation may
vary from twenty minutes sometimes to five hours.
The fermenting room should be cool, airy and
humid, and the leaf is usually spread on fermenting
tables or on cement floors. The room temperature
should be around 75* to 80* F. A long fermentation
at lower temperatures tends to destroy flavour,
and a shorter fermentation gives raw and bitter
liquors. When flavour is evident, a shorter
fermentation may be the best, but a study of
local conditions will help to obtain the best.
Drying
Dryers are of many makes,
but the essentials are that it contains a stove
for heating air, a fan to draw it and direct
it to the drying chamber. It contain a series
of perforated metal trays so arranged to carry
the leaf feed from the first tray to the last
thereby imparting the maximum heat required
to dry the tea completely. The machine can dry
the tea within 20 to 25 minutes.
The temperature of the hot air as the tea may
vary between 180* to 200* F. Higher temperatures
and longer through time can kill quality. At
the point of discharge, moisture contents would
have reduced to around 3%. The tea will not
keep if the moisture contents are above 4.5%.
The fermented leaf is dried to stop any further
chemical reactions taking place. The keeping
qualities of tea depend on the temperature at
which the tea has been fired. The technology
of tea drying depends on many factors, the most
important being firing temperatures. The most
important being the temperature at which firing
takes place. The volume of air, the load of
leaf in the dryer trays, the period of drying,
and the inlet and exhaust temperatures too play
an important part in the drying process.
Grading
As the last operation
in this long process of manufacture, the fired
tea is then graded. It is the final but one
of the important processes in tea manufacture,
which could make all the value for the final
product. The separation of tea particles into
different shapes and sizes, conforming to trade
requirements, involves many operations. This
process can get long and tedious, when large
number of grades is made. This is particularly
so in low grown areas, where the factory elevation
does not exceed 2,000 feet above sea level.
Grading up to twelve to fifteen grades is not
uncommon in these factories.
It must be emphasised that the various grades
of tea only denote a certain size and appearance
of leaf; it has no reference to quality. Broken
grades normally give darker liquor and a stronger
tea. Leaf grades on the hand, are lighter coloured
and less strong.
The graded teas are finally weighed and packed
into tea chests. Such is the mode of careful,
clean preparation that goes on in many hundreds
of tea factories situated at all elevations
from sea level to over 6,500 feet.
Marketing of Tea
Reporting on musters
When an invoice is ready
on the estate, which could comprise one grade
or different grades, the superintendent draws
from the bulk two sets of samples. One set is
rushed to the managing agents and the other
set to the selling brokers in Colombo for tasting
and reporting. This specialised job firstly
involves a close examination of the dry leaf
to ascertain whether it conforms to the specifications
laid down for the grade. Then the infusion is
carefully examined to determine its acceptability,
and lastly the liquor is tasted to gauge its
merits from the point of view of manufacture
and specific consumer demands.
These are termed "Muster Reports"
and are a careful analysis of what goes on in
an estate hundred of miles away. The tea taster
in Colombo acts as a guide to the superintendent
and the factory staff, and if a mistake in manufacture
is spotted, it is brought to their notice before
the general standards deteriorates further.
All brokers have their own manufacturing advisers,
and regular visits to the estates are undertaken
by them to ensure that the right type of tea
is made in keeping with market requirements.
Overseas tea buyers could get extremely fastidious,
and their requirements could vary considerably
from country to country. Leaf appearance of
made tea is most important in its presentation
and should be black, neat and even, well twisted,
clean and stalk free. Infusions should be as
far as possible bright. In the liquors there
are wide variances. Teas could be light and
thin, extending to thick, pungent and heavy
teas, and others could be flavour seasonal teas.
A close examination of these various properties
by the experienced tea taster provides the estate
staff the necessary guidelines regarding exact
market requirements.
Meanwhile, the superintendent on the estate
continues to push the teas on their way to the
outlets. When sufficient teas are collected
to form an invoice, they are bulked and packed
and dispatched to Colombo if intended for disposal
in the Main sale, or retained on the estate
if meant for Ex-estate sale. In the case of
Ex-estate sales, a three-kilo sample is drawn
from three packed chests at random by a responsible
person in the factory and dispatched to their
selling brokers in Colombo, along with the invoice
particulars. In the case of main Sale teas,
their respective managing agents usually furnish
cataloguing details to the brokers.
On average, about fifty sales are conducted
during the year, and weekly offerings could
vary from seven million kilos during the rush
months. Quantities however could decline to
around three million kilos during the lean months.
Generally, main sale offerings are greater in
comparison to Ex-estate sales. More than a million
kilos of tea arrive in Colombo each day either
for disposal through the Main sale or consigned
to buyer’s stores those teas sold under
Ex-estate terms.
Cataloguing and
Sampling
Catalogues usually close
each week, three weeks ahead of the actual sale
date. Main sale catalogues normally close on
a Monday, and Ex-estate catalogues two days
after on Wednesday. It is at this stage that
the broker becomes directly concerned with the
journey of tea.
Today, brokers are called upon to serve about
150 tea buyers. It is a statutory requirement
that all buyers at the tea sales are registered
with the Tea Control Department, whilst some
of them are also members of the Colombo Tea
Traders Association. All these buyers are entitled
to a regulated number of samples, while about
fifty of the larger buyers are entitled to the
full set, which mean, a sample from each lot
offered for sale.
The number of lots offered each week could vary
from about 9,000 to over 10,000 depending on
the crop situation. It has become necessary
for all the brokers to distribute over 90,000
samples of the different types of tea offered
for sale each week.
These samples are made available to the trade
together with the printed copy of the broker’s
catalogue two weeks prior to the actual sale.
Some buyers very often call for samples even
earlier for onward transmission to their overseas
buyers, and this often happens during the quality
season, where the buyers taste the teas before
placing bids with their shippers in Colombo.
For this purpose, the respective brokers box
samples. In the case of main sale teas, a three-kilo
sample is drawn from three chests chosen at
random by the broker's representative. Boring
a hole on the side of the chest does this. After
the required amount of sampling material is
taken, the hole is sealed with a metal bung.
In the case of Ex-estate teas, the samples that
are dispatched from the estates are separately
boxed in the sampling room of the respective
broker. These samples are distributed among
the various buyers many of who provide their
own set of tins. Others are provided with samples
wrapped in special paper.
It is at this stage that the teas are tasted
for valuations. The broker's taste and value
their teas and a valuation is placed on each
lot. These valuations provide a guide to the
prices that could be expected for the buyers
when the lot comes up for sale. The buyers also
taste the full range of samples sent to them
by the brokers and value them separately. Their
ultimate interest is the quality of the end
product and their final reckoning is "what
is the tea worth to the company," and where
can I find a home for the tea purchased. The
ultimate price paid at the auction depends on
many factors such as market trends, overseas
demand, shipping opportunities, availability
of credit, etc. Taking all these factors into
account, the buyer fixes a price in keeping
with his requirements and places a limit on
each lot he is interested in purchasing.
Disposal of tea
The producer of tea has
a number of alternative methods by which he
may dispose of his tea. The method most commonly
used is to offer his produce for sale through
the public auctions. He is also permitted to
offer individual invoices for Private Sales
at a price mutually agreed by a panel of tasters.
The government has now extended this facility
further to enable a producer to sell 50% of
his crop forward for a period of six months
under a Forward Contract that too is negotiated
at a fixed price by a panel of tasters.
Despite these various methods of disposal granted
to the producer by the government, the majority
of producers usually favour selling their crop
locally in Colombo. Over 90% of the crop is
sold each year through the medium of the public
auctions. Producers were also permitted to consign
their produce to the UK for sale through the
London Auctions. This London Auction has now
ceased to function.
The auctions in Colombo are organised by the
Colombo Tea Traders Association in accordance
with a set of laws formulated by the Sri Lanka
Tea Board. They are usually held weekly throughout
the year at the Chamber's office in Colombo.
The auctions are open to all interested parties
provided they are registered tea dealers. The
majority of those operations in Colombo are
members of the Colombo Tea Traders as well.
Buyer's Advices
The larger weight of tea
exported from Sri Lanka is shipped in its original
form, for example, under the estate's own name,
in the original chests, as packed on the estate.
This type of consignment is generally made against
orders received by exporters from their overseas
associates who do their own blending generally
with teas from other countries. Quite a large
volume of business is also conducted in blended
form. This operation is carried out in buyer's
warehouses and shipped against orders received
for a particular type or standard of tea. There
is also a trend fast developing for value addition
locally. In this case, the teas are not only
blended but also packaged locally. These pre-packed
teas could be shipped under the exporters own
brand name, or under the mark of ownership of
the overseas buyer.
A very large percentage of the teas sold in
Colombo are generally bought by exporters against
firm orders, or on instructions received from
their overseas associates with whom they have
had long years of relationship, with the result
they know their exact requirements in serving
those particular markets.
Trading in tea on the other hand, where teas
of good value are purchased in the hope of selling
them later on actual offers has diminished considerably
over the years due to the high cost of finance.
The overseas buyers when placing orders in Colombo
with their agents, not only take into account
the quality of the teas available locally, but
also the market conditions prevailing in other
countries for similar quality. His conception
is to obtain his requirements at the cheapest
possible price, and before placing a firm order;
he will make a thorough study of price levels
prevailing in other auction centres. Prices
paid in Colombo reflect international levels,
and it is imperative that if we are to maintain
optimum price levels locally, the product is
of best possible quality, both in respect of
quality and leaf appearance. Another specific
factor that may stand in favour with a particular
shipper is his ability to effect speedy shipments
of their consignments.
Auctioning of
Teas
The next step in the journey
of tea is when the tea change's hands at the
Colombo Auctions. Each broker enters the rostrum
in turn and proceeds to sell his catalogue.
Each catalogue may have 259 different teas for
sale, which could mean about 750 to 850 lots
comprising various types of tea. The broker
will have his own valuation on each lot of tea
he expects to sell. The buyers too have copies
of the broker’s catalogue, and after tasting
the teas they are interested in, they will note
down under each lot their idea of price.
It is at the auction, that the buyers purchase
their requirements competing against each other
for the highest bid. The selling broker on the
rostrum follows the order of the catalogue calling
for bids on each lot. Buyers compete and on
the best bid, provided the broker is satisfied
that he is getting a fair price according to
the sellers' instructions, the lot is knocked
down. If the broker is not satisfied with the
progress of the bids, he makes a quick decision
to withdraw the particular lot from the sale.
These withdrawn teas are offered to interested
parties as out-lots after the sale, or re-catalogued
for a subsequent sale.
The buyer to whom the lot is knocked down becomes
the owner of the particular lot. Although it
is a verbal contract to purchase the tea, it
becomes an irrevocable bond between the buyer
and the broker. The buyer is now under obligation
to make his settlement of cost with the broker
within one week of the auction date. Once this
is done, the buyer gets in return a delivery
order to obtain his purchases from the sellers'
stores, if the purchase includes main sale teas.
In the case of Ex-estate teas, the broker issues
delivery instructions to the estate as to where
the tea should be delivered. The teas that have
so far been in the possession of the seller,
now moves into the custody of the buyer.
The Colombo Tea Auction that is the largest
selling point in the world, is the cross road
of the journey of tea from the producer to the
consumer. A verbal contract becomes an irrevocable
bond at the fall of the hammer. Generally over
10,000 lots come under the hammer each week,
and an experienced broker will aim at selling
about five to six lots per minute.
