There are six varieties of tea; white, yellow, green, oolong, black and pu-erh
The difference between Black, Green, and Oolong tea is a result of the changes that occur during processing of the tea leaves.
They are all made from the same type of tea leaves.
Black teas are fermented, left in a cool, dark, and damp place for a time, and then heated to stop the fermentation process.
Oolong teas are semi-fermented.
Green teas are heated after picking… so there is no fermenting process.
Herbal teas are not actually teas, but are concoctions of peels, flower leaves, herbs, and spices, and are caffeine free.
The caffeine content of tea is 40 mg in one cup of tea as compared to 99 mg of caffeine in a cup of coffee.
Black and Green teas contain a certain type of antioxidant called flavenoids.
Today tea is the world's second most popular beverage consumed, second only to water. It's easy to make, affordable, and offers variety in its flavors and aroma.
