In the ceremonial style, in which you taste matcha directly, you can enjoy the completely different tastes of matcha from Usucha and Koicha. In Japanese, "Usucha" means "thin tea," and "Koicha" means "thick tea."
Generally speaking, usucha is the most common type of matcha. Drinking it as it is, you can enjoy its fresh aroma, rich flavor, and moderate bitterness with fine bubbles. Combined with milk, it is easy to make a matcha latte.
Koicha is truly a ceremonial drink. It uses an abundance of refined, high-quality matcha for entertaining important guests. Koicha is about three times thicker than Usucha. Its taste is unique, mild, and impressive because it is made from high-grade matcha with almost no bitterness and a rich, mellow umami taste.
