The name of this sosticated Japanese tea translates to âjade dewâ, describing the color of its infusion. Our gyokuro is grown in rich volcanic soil on the south eastern coast of Kyushu, an area known as a leader in organic farming practices. âUmamiâ in taste and aroma, with a sweet rich finish, the leaves are very fine, needle-shaped and a brilliant dark green color due to being shade grown, which gives gyokuro a higher chloroll content than most teas
