Katsunuma Jyozo is one of Yamanashi’s top producers of Koshu wines. Using exclusively grapes grown in Katsunuma-cho, it controls every winemaking step from viticulture to bottling. Katsunuma is relatively new among the world’s great winemaking regions.
Grapes have been grown here for 1,000 years but wine only produced for 130 years. Katsunuma Jyozo however, continues the tradition established by its founder, producing and improving wines that express to the full Katsunuma’s history and culture, fully committed to the principle that wine exists to allow connoisseurs to savour the terroir in which the grape is grown.
