The characteristic and slogan of Namacha is the use of raw tealeaves extract which also shows in its very name Namacha raw tea. This raw tealeaves extract contains rich amount of teanin , the component that gives mildness and the unique unsugary sweetness to green tea. In order to fully bring out the teanin flavor and benefits, Namacha only uses the tealeaves of Gyokuro, Kabuse-cha and Fukamushi-cha and brews the leaves at very low heat, straining it only roughly.
