The origin of the white grape variety is unclear. Supposedly it was grown in 1965 by Dongfeng Farm along with other grape varieties such as French wild and Rose Honey in China introduced. According to another hypothesis, it came from Europe at the beginning of the 19th century, for which there is no evidence. According to the Chinese ampelograph Qin Sun, it is a cross Vitis vinifera x Vitis labrusca, But this has not yet been resolved DNA analysis approved. It may be identical to the US Labrusca variety from Connecticut of the same name, which is in the VIVC catalog as table grape to be led. The VIVC catalog also includes another table grape variety called Kristal (with the synonym Crystal) with origin South Africa specified.
The early ripening vine (from China) is very resistant to frost and generally against vine diseases. She delivers white wines Foxton (which speaks for Vitis labrusca genes) and rose like Aroma and is also called table grape used. The variety is mainly grown in the southwestern province of Yunnan. In 2010, acreage was planted in Russia (171 ha), as well as overseas Chile (2 ha) and Peru (2 ha), but no quantities are shown for China (Statistics Kym Anderson ). It is unclear which of the possibly different types of crystal are involved.
