World-Class Koshu, from Japan to the World
Koshu is an indigenous Japanese grape variety with more than 1,300 years of history.
Katsunuma Jozo’s dream is to move people around the world with wines made from Koshu grapes.
We are uncompromising about the grape variety itself and cultivate the fruit with our own hands. Even during pressing, we work slowly and gently, without placing unnecessary stress on the grapes, drawing out their natural character and flavor.
We pursue winemaking that satisfies us in every detail.
From that conviction comes our greatest confidence.
