This Premium Grade Matcha is the best of the Matcha currently offered by Aiya. Of the over 200 farmers in Nishio city that are contracted by Aiya, only a select few have the experience and knowledge necessary to produce Matcha high enough in quality to be called “Premium Grade.” The result of their efforts is a rare treat. Aiya Matcha's Premium Grade Matcha has a robust Matcha flavor packed with tons of natural sweetness (umami flavor) derived from the amino acid L-theanine. Ideal to be served as Koi-cha (thick style Matcha), this grade can also be enjoyed as Usu-cha (thin style Matcha). Although we recommend this Matcha for use on special occasions, you can enjoy this luxury everyday if you so desire. All of Aiya's Matcha is grown and produced in Nishio city in Aichi prefecture. Nishio has been known the world over as the cradle of the finest Matcha for more than 800 years.
