atcha is the vibrant green powdered tea used in traditional Japanese tea ceremonies. It is made from the leaves of shade grown tea trees. When the leaves are harvested they are steamed, dried and then further processed to remove the veins, stems and impurities. Only about 10% of the original harvest remains, and this is called the “tencha”. The tencha is then ground to a fine powder often in a stone mill. It takes about one hour to produce an ounce of matcha, because grinding any faster would result in a burnt tasting tea. Today the highest grades of matcha usually remain in Japan for use in their tea ceremonies and the price can be as high as $100 an ounce. The majority of matcha available in the general market today is now ground by sophisticated machines, which make it affordable to the average tea drinker. Regardless of the grinding technique used, the production of matcha requires a great deal of hand labour, skill and time.
