Different types of teas come from the same type of tea leaves

There are 6 types of teas that we are drinking today, including white tea, green tea, yellow tee, oolong tea, black tea, and dark tea (or post-fermented tea). However, all those teas come from the same Camellia Sinensis plant. It's the processing of the tea leaves, not the type of plant, that determines the different types of teas. In other words, different processing methods lead to varying levels of oxidation and fermentation, and hence different types of tea. White tea is hardly fermented, green tea is slightly fermented, oolong tea and black tea are more fermented, and dark tea leaves are left to fully oxidize until it turns the color black. Therefore, regardless of location, a single tea garden can produce all 6 types of teas if the maker has the craftsmanship and the skill to do so.

A lot of people think that different types of tea trees will produce different types of teas, since there are also other types of "teas" like rooibos, yerba mate, chamomiles, and other caffeine-free "teas". In fact, they are indeed from different plants, but they are "tisanes", not "tea". "Tisane" is a French word for herbal infusion, but it is not as widely used as "tea", perhaps the word "tea" is more suitable to describe the little ingredients you put in hot water to make a calm drink. Nonetheless, you can differentiate them very easily since they look physically different, and they taste different too!
