...Black tea leaves are made by exposing them to a gentle heat to be wilted, then rolling, oxidizing and allowing them to dry. These small leaves produce a tea that is dark brown or black, with a flavor that is strong and slightly floral or fruity. The flavor of black tea varies, some might be smoked, fermented, or have flavors added to them. Unless decaffeinated, this tea always contains caffeine and can be served hot or cold.
