The word "tea" (chá in China, chai in India) makes reference to one particular species of plant, called "Camellia Sinensis", and the drink made from steeping its leaves in water. The four types of tea; White, Green, Oolong, and Black refer to the differences in possessing that the leaves go through.
History of the Drink
It is almost certain that tea as a drink originated in southeast Asia many thousands of years ago. This is not surprising as civilizations have been eating and drinking the plants and animals around them since the dawn of time. In South America people drink Yerba Mate, and in South Africa its Rooibos, to name a two. What has changed over the centuries is the way that such things are consumed.
Time line:
- 500 BC, The Chinese philosopher Laozi wrote about the heath properties of the plant, going so far as to include it as the main ingredient in his "elixir of life".
- 220 BC, physician Hua Tuo wrote about tea's ability to improve the mind as well as the body.
- 59 BC, Wang Bao wrote instructions on buying and preparing tea. This signaled a transition from tea being purely a medicine, to being an integral part of the diet.
- 600 AD, Japan became interested in Chinese culture, and sent Buddhist monks to investigate. Thus, tea was introduced to the Island of Japan.
- 661 AD, In Korea tea was used as an offering to the spirits of kings.
- 760 AD, Lu Yu describes tea drinking as a common practice. During this period tea leaves were steamed and compressed into " tea bricks" for easy transportation and exchange. They were often used as a form of money further from the empire as coins lost their perceived value.
- 1000, Tea leaves were still steamed, but not necessarily compressed into bricks. This ensured that the delicate taste, preferred by many, was maintained.
- 1250, other ways of processing tea leaves started to be used in China.
- 1391, the Ming court would only accept loose tea as a "tribute." Production of tea brinks started to decline as the demand for loose leaf increased.
- 1550, A Buddhist monk named Sen no Rikyū developed what could be considered the base of modern day Japanese tea ceremony.
- 1598, A Dutch sailor witnessed the consumption of tea in India. However, this is most likely simply the first observed consumption, hinting at a long history for the Indian plants.
- 1600 The Dutch East India Company brought the first tea leaves to Amsterdam from China, it was a green tea.

Processing the plant into a Food
The level of Oxidation is the main determining factor in what type of tea the leaves of Camellia Sinensis become. Put simply Tea is on a spectrum of oxidation. White tea has the least, followed by green, oolong, and then finally black, which is "fully" oxidized. Leaves begin to oxidize as soon as they are picked, turning darker as oxygen breaks down the chlorophyll. This process, enzymatic oxidation, is sometimes erroneously called fermentation in the tea industry. The withering and darkening of the leaves are not caused by micro-organisms, nor is it an anaerobic process.
