Gyokuro is widely regarded as one of the highest grades of Sencha (Japanese green tea) due to its more laborious cultivation process. Unlike uncovered Sencha leaves, Gyokuro tea leaves are shielded from the sun for about three weeks before being harvested. This process causes the theanine and alkaloid caffeine in the leaves to increase and results in a richer flavor. Please note that Gyokuro is steeped at a lower temperature for a longer duration than standard green teas.
