About This Product This organic Matcha is from a 100 year old tea company in Nishio region of the Aichi Prefecture, located deep within the heart of Japan’s main island, Honshu. The region is known for its rich history of Matcha production. Matcha is ground into a powder from green tea leaves (known as Tencha) using grinding wheel stones. The quality and artisanship of these stones is a key factor in determining the quality of good Matcha. There are less than 50 remaining Masters who still practice this ancient art of stone carving in Japan today. Ingredients: Organic Green Tea Leaves. Available in a sealed 1 oz tin.
