Koshu (甲州 kōshū) is a white wine grape variety that has been grown primarily in Katsunuma Yamanashi Prefecture of Japan. It was developed from grapes that were brought from the Caucasus through the Silk Road, at a period estimated to be around a thousand years ago. Though long thought to be of exclusively European origin, it is now known to be a hybrid of Europe’s Vitis vinifera and one or more Asian Vitis species.
The distinctive characteristics of Koshu are a pale, straw colour and a soft, fruity bouquet with overtones of citrus and peach. The taste is clean, delicate and fresh, considered a good pairing for Japanese cuisine. With a zen-like quality it is also a good match for any Asian or western cuisine, which is inspired by fresh seafood, light meats and vegetables.
