Quick Summary

Green tea is a type of tea made from the leaves of the Camellia sinensis plant that have not been oxidized before drying. This process results in a beverage that is light in color, with a mild, pale green or lemon-yellow liquor that can be slightly bitter.12

Unlike black tea, which undergoes fermentation, green tea's oxidizing enzymes are deactivated by steaming or roasting the leaves before rolling and drying. This preserves the natural green color and results in a weaker flavor compared to black tea. Green tea is primarily produced in Japan and China.2
