The red grape variety originates from Japan. Synonyms are Crimson Glory Wine, Yamabudo and Meoru (Korea). It is a variety of the Asian vine species Vitis coignetiae. The late-maturing vine is susceptible to downy mildew and botrytis. It produces dark-coloured, acid-emphasised red wines with a green note. The variety is also used as table grape. It was a crossing partner for the new varieties Yama Sauvignon and Yama Sémillon. During the phylloxera catastrophe in the 19th century, a red wine made from it was even exported to Europe. The variety is cultivated in the provinces of Aomori, Nagano, Okayama and Yamagata on the main island of Honshu. In 2016, 35 hectares of vineyards were designated here (Kym Anderson statistics). Small stands are also said to exist in South Korea.
