History
“Komazono” is the local field name of the winery's estate vineyard, where Koshu grapes were cultivated even before the winery was founded.
Carrying forward its founding philosophy of “winemaking close to nature,” Komazono Vineyard is a small Japanese winery committed to using 100% Yamanashi-grown grapes in every wine. It works primarily with its own vineyards, supplemented by grapes carefully cultivated by local contracted growers.
Today the winery manages 12 parcels across four sites in Yamanashi Prefecture, totaling approximately two hectares, including the Komazono vineyard, which contains old Koshu vines estimated to be more than 80 years old. Taking advantage of Yamanashi's varied natural environments at elevations from 280 to 620 meters, it grows Koshu, six European varieties, and five Japanese-bred varieties.
Annual production is approximately 35,000 bottles of Japanese wine.
