Researchers at Okayama University of Science (OUS) have developed a new wine grape variety, “Muscat Shiragai,” by crossing the rare wild Shiraga grape—found only in Okayama Prefecture—with Muscat of Alexandria. The team, led by Professor Emeritus Takuji Hoshino, has filed for official registration of the new variety with Japan’s Ministry of Agriculture, Forestry and Fisheries. The project, launched in collaboration with Kurashiki City and Funao Winery, aims to revitalize the region through locally branded wine production. Early tastings of Muscat Shiragai grapes and wine have been well received for their sweetness, smooth flavor, and subtle Muscat aroma.
