Oolong, black, green, and white tea are made from the same plant.
These tea varieties come from one tea tree called Camellia sinensis. Despite they are harvested from the same tea plant, oolong, black, green, and white tea differ in the way they are treated. All tea leaves are withered, rolled, and heated. The varieties are created based on the additional steps, the timing of processing, and other actions taken before the leaves are packaged.
Iced tea was invented be the Americans as well in 1904.
Another US invention is iced tea, although there is also a version that it was invented by a British tea seller at the World Exhibition in St. Louis in 1904. Iced tea is consumed most actively in the United States – 85% for iced tea VS 15% for hot tea.
The Japanese nobility in the 14-15 centuries organized tea tournaments.
Tea tournaments became very widespread among the Japanese aristocracy during the period of the 14-15th centuries. It was noble and respected to understand the tea varieties and their unique features. The point of such kind of competitions was to guess by flavor the type of tea and the place of its origin.
Tea is still harvested manually.
Tea is so far relatively expensive because it is harvested and sorted manually. All attempts to create special equipment for these purposes failed: collected leaves are mixed with stems, shoots and other debris. Machine-assembled tea is used either for the production of tea of the lowest category, or for the extraction of caffeine from leaves, used in cosmetology and pharmacology.
