How and when exactly the invention of green tea came about is still a matter of opinion today. However, everyone agrees on one point - the green bedrock is one of the oldest and most popular teas in the world. With their bright green leaf and cup color, teas of this variety really live up to their name. The taste of green tea is almost as varied as the numerous legends that surround it. Flowery jasmine tea, spicy gunpowder or mild sencha - everyone gets their money's worth here. Green teas usually contain caffeine and are therefore very stimulating and refreshing, especially in the morning.
