Aged and enriched Matcha known as Kuradashi Matcha is very special to all those who engage in tea ceremony. In the Japanese tea ceremony, even today, people celebrate aged Matcha in the ceremony called Kuchikiri no Gi every autumn. Traditionally, a special tea jar filled with Matcha was stored in a cool place like the top of a high mountain or in the ground after harvest until autumn. People would first enjoy that year's Matcha in the autumn after the Kuchikiri no Gi ceremony. And it was said that when the jar lid was opened in autumn, the marvelous fragrant aroma was savored. Indeed, when we open a package of our special Kuradashi Matcha, here at Hibiki-an, that has been aged for more than one year, the aroma is so amazing that there are no words to describe it.

To correctly age Kuradashi Matcha, there are many rules and special procedures one must follow.
Tea leaves should be stored not in powder form, but as Tencha. Tea leaves before they are ground into fine powder, but after stems and veins are removed, are known as Tencha. For Kuradashi Matcha, the Tencha is ground into powder by a stone mill called Ishiusu just before it is shipped to the customer. The reason for this is because when Matcha is ground into a fine powder, it deteriorates more easily than tea leaves such as Gyokuro and Sencha due to the fact that there is more surface area exposed to the air. If one tried to age Matcha powder for more than one year, as we do with Tencha for Kuradashi Matcha, it would not enrich but just deteriorate.

In order to age and enrich well, tea leaves need air, oxygen. The Tencha tea leaves are stored in open, unsealed foil bags in a special refrigerator that is somewhat cool, but not too cold. We keep a flow of fresh air constantly circulating through the refrigerator, allowing oxygen to mix with the tea. In this way, the tea leaves are allowed to breathe over time and enrich.

When Tencha is ground in the stone mill known as Ishiusu, the temperature is 60 to 70C (140 to 158F). The moderate heat deepens the mellow taste of the Kuradashi Matcha. The stone mill can grind only 70g (2.5oz) per hour. It takes a long time to grind the Tencha into Matcha, therefore some tea companies have several stone mills, which are very expensive and require a huge space. Though today's stone mill is turned by an electric motor, not by hand, most parts of today's stone mill are quite the same as the traditional stone mill of many years ago. Even today, the grooves of the great stones used in the mill which grind the tea are hand-carved by skilled craftsmen.
Today many manufactures tend to use power disintegrator machines to create Matcha, as it is much more efficient than traditional stone mills. Middle and low grade Matcha is often made using a power disintegrator machine. Only high and highest grade Matcha, such as our Kuradashi Matcha, is ground by traditional stone mill to deepen the mellow taste.

As above, to create the unique and subtle mellow flavor of Kuradashi Matcha, which enhances in the mouth and lingers for a while, a great deal of time and care are devoted not only to growing tea at the tea farm but also to the special process to turn fresh tea leaves into perfectly-aged Kuradashi Matcha.

We are planning to sell three limited edition Kuradashi Gyokuro, one Kuradashi Sencha, and three Kuradashi Matcha only available mid-autumn. Please wait and see!
