Who owns and runs Ohizumi Winery?

It is a cooperative: roughly 100 local grape-growing families in Katsunuma's Iwasaki district are joint shareholders, and the winery is run in partnership with them rather than by a single owner-winemaker.

How old is Ohizumi Winery?

It dates to 1902, when it was founded as Daruma Grape Wine Co.; it adopted the Ohizumi name in 1963, giving it well over a century of winemaking history in Katsunuma.

What grape does Ohizumi Winery specialize in?

Koshu, Japan's native white grape, grown by its own shareholder farmers in Katsunuma — it forms the base of the winery's signature Kaori Koshu series.

What is distinctive about their vineyard practices?

Since 2005 the winery has used non-Bordeaux-mixture cultivation, avoiding the copper-based spray that can break down the citrus aroma compounds naturally present in Koshu grape skins.

What is Ohizumi Winery's best-known wine?

The Kaori Koshu ("aromatic Koshu") series is its signature label, alongside the everyday-drinking Katsunuma no Jizake table wine.

Ohizumi Winery is a cooperative winery in the Iwasaki district of Katsunuma, Koshu City, Yamanashi — jointly owned and financed by roughly 100 local grape-growing shareholder families. Its roots trace to 1902, when it was founded as Daruma Grape Wine Co., and it took the Ohizumi name (from its local district) in 1963. The winery crafts wines almost exclusively from Koshu grapes grown by its own shareholder farmers, and since 2005 has practiced non-Bordeaux-mixture cultivation to preserve the citrus aromatics naturally present in Koshu skins. Signature bottlings include the Kaori Koshu series and the everyday Katsunuma no Jizake ("local sake of Katsunuma") table wines.
