A Brief History of Koshu Wine
The Koshu grape has been cultivated in Japan for over 1,000 years, believed to have arrived via the Silk Road. Though initially grown as a table grape, local vintners in Yamanashi began producing wine from Koshu in the late 19th century. Since then, it has evolved into Japan’s most celebrated white wine, praised for its subtle citrus notes, mineral freshness, and natural pairing with Japanese cuisine.
Today, Koshu wines are internationally recognized, with many wineries in the valley winning awards for their still and sparkling varieties.
