There are several main types of tea, each derived from the Camellia sinensis plant. The primary categories include green tea, black tea, oolong tea, and white tea. Green tea is minimally processed, preserving its natural green color and antioxidants. Black tea is fully oxidized, resulting in a stronger flavor and darker color. Oolong tea is partially oxidized, offering a taste that falls between green and black tea. White tea is the least processed, made from young leaves and buds, providing a delicate flavor. Each type has unique characteristics and health benefits, appealing to different preferences.
