History
Koshu is a white wine grape variety that has been cultivated in Japan for over a thousand years, primarily in the Yamanashi Prefecture. It is believed to have arrived in Japan via the Silk Road, originating from the Caucasus region. Recent DNA analysis suggests that Koshu is a hybrid of Europe's Vitis vinifera and one or more East Asian Vitis species. The grape was officially recognized by the International Organisation of Vine and Wine (OIV) in 2010, highlighting its significance in Japanese viticulture.
Appearance

Growing Traits
Koshu grapes have evolved to suit the Japanese environment, with their thick skins making them comparatively resistant to disease in the humid climate. They thrive in well-drained volcanic soils and benefit from significant temperature fluctuations between day and night, which help preserve their natural acidity.
