Green tea has been enjoyed since ancient times in China (the origin of tea) and Japan, where it is most frequently drunk. Green tea has also gained in popularity among Europeans and Americans in recent years for its health-giving properties. When water is added to green tea leaves, the resulting beverage retains the color of the freshly-picked leaves. Green tea therefore offers an even fresher, more natural flavor. Green teas are categorized according to type and production method, and flavors vary. In general, however, green tea is made in China by roasting the tealeaves in a pot, offering a refreshing, aromatic flavor. In Japan, the green tea leaves are steamed, producing a sweet, delicate flavor.
