    • Black tea and green tea are both made from the leaves of the Camellia sinensis plant, but they are processed differently. Black tea is made from leaves that are fully oxidized, which gives it its dark color and strong flavor. Green tea is made from leaves that are steamed or pan-fried to stop the oxidation process, which preserves the tea’s natural green color and delicate flavor. The difference in processing also affects the caffeine content of the two teas. Black tea typically has a higher caffeine content than green tea because the oxidation process releases more caffeine from the leaves. However, the exact amount of caffeine in any given cup of tea can vary depending on factors such as the type of tea, the method of brewing, and the length of time it is steeped.
