There are many different types of tea, from herbal teas to black, green, and white teas. Herbal teas are made from various plants and flowers, and are naturally caffeine-free. Black tea is fully oxidized, giving it a bold, robust, and slightly astringent flavor. Green tea is unoxidized and has a more delicate flavor than black tea. White tea is the least processed of all teas and has a subtle, sweet flavor. There are also scented and flavored teas, which are made by adding natural extracts and oils to the tea.
