THE TEA PLANT: Camellia Sinensis
The tea plant is a species of tree related to the camelia. Its flowers are yellowy-white and its fruits small and hard-shelled, similar to a hazelnut. The evergreen leaves are leathery, dark and slightly serrated. Given minimum annual temperatures of 18° C, moderate and infrequent frosts, a uniform annual precipitation of 1600 l and a good balance of sunshine, a tea plant can easily grow to become 100 years old. Wild tea plants are indeed reputed to reach an age of up to 1,700 years.

PROCESSING THE TEA LEAVES
It's a long day of picking since it takes a very large amount of fresh leaves to made the pound of tea you buy. Methods vary in harvesting the tea; either it is picked by hand(orthodox)or by a machine. Either way the goal is the same, top 2 leaves and a bud.
There are usually 3-4 pickings per year (first flush, second flush, autumal and monsoon pick). Each picking has it's subtle differences in taste. Tea is a plant which takes on the characteristics or tastes of it's environment, much like wine.
The processing of the leave is what gives us the range of teas we are use to. Black tea is cut and crushed to give it close to 100% oxidization. Oolong tea is oxidized to about 20%. Green & white teas are not oxidized (green tea is steamed). These categories of tea all come from the same plant but are processed differently.
