A top-class Japanese Sencha tea, also known as the 'Dew of Pearl' or 'Most Exquisite Dew Drop', Gyokuro tea plants are grown in the shadow of broad-leaved trees and shaded with bamboo mats for two weeks before being plucked to boost the chlorophyll content and the green character of the tea. It has a high caffeine content and low tannin, and the infusion is mild and typically tangy.
