Gyokuro

Gyokuro (玉露) is a fine Green tea from Japan. Some time before gyokuro is harvested, the tea plants are covered with shades, which slows down the leaf growth, increases the amount of caffeine, and makes the leaves a bit darker than most green teas.

Gyokuro is usually quite expensive and not widely available. Most of this premium tea is grown in the Uji area of Japan.
