Tea isthe most popular drink in the world after water.There are thousands of different kinds of tea.All tea comes from the leaves and buds of the tea plant.After picking the leaves and buds,the farmers process them into black tea,oolong tea,green tea or white tea.
Black tea was invented in China in the Ming Dynasty as a way to keep tea fresh.As tea has to travel a long way to reach places such as the UK,Canada and Australia,Westerners drink mostly black tea.
However,the majority of the world drinks green tea.Herbal tea is not really tea.It mainly contains herbs,fruits,spices,but no leaves must come from this plant.
All tea naturally contains caffeine.Caffeine is in the tea leaves.Decaffeinated tea is regular tea(usually green or black),but people have processed it to take away the caffeine.
In recent years,organic tea has also become popular.It is tastier and healthier.However,usually it costs more than non-organic tea.This is because the size of the tea crop is often small
