The red grape variety is an interspecific new variety between Bailey x Golden Queen. It contains genes from Vitis labrusca, Vitis lincecumii and Vitis vinifera. The hybrid was crossed by Zenbai Kawakami (1868-1944) in Niigata (Honshu) in Japan. The variety Pokdum (also Pok Dum) grown in Thailand is a mutation. The variety was a crossing partner in the new Cabernet Suntory variety. The very late ripening vine is susceptible to botrytis. It is mainly used as table grape, but in some Asian countries, especially Japan, it is also used as a wine grape. Here it occupies 28 hectares of vineyards. There are other stocks in Cambodia (3 ha), Taiwan (94 ha), and Thailand (18 ha). In 2016, a total of 143 hectares of vineyards were reported (Kym Anderson statistics).
