The red grape variety comes from Japan. Synonyms are Crimson Glory Wine, Yamabudo and Meoru (Korea). It is a variety of the Asian vine species Vitis coignetiae. The late ripening vine is susceptible to downy mildew and botrytis. It produces dark-coloured, acidic red wines with green notes. The variety is also used as a table grape. It was a cross-breeding partner in 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 grown in the provinces of Aomori, Nagano, Okayama and Yamagata on the main island of Honshu. According to Wine Grapes, it occupies 158 hectares of vineyards. Small stocks are also said to exist in South Korea. However, Kym Anderson's statistics did not show any stocks in 2010.
