Koshu (grape)
| Koshu (甲州 kōshū) is a white wine grape variety that has been grown primarily in the Koshu Valley in Yamanashi Prefecture, Japan. Though long thought to be of exclusively European origin, it is now known to be a hybrid (probably naturally occurring) of Europe's Vitis vinifera and one or more East Asian Vitis species.[1][2] The name “Koshu” is a former name for Yamanashi and the present-day name of the main town in the valley where the majority of Koshu grapes are grown.[3] | ||||||
