Black tea is the most popular type of tea worldwide. It’s one of four types made using the leaves of the camellia sinensis plant—the others are green, oolong, and white teas. The difference between the types of teas is in how they are processed.
Unlike other teas, black tea leaves undergo an extensive oxidation process, exposing the cells inside the leaves to oxygen. Experts believe this oxidation may benefit black tea differently than green tea (which receives no oxidation). Both oolong and white teas undergo partial oxidation.
