The red grape variety is an interspecific new breed between Seyve Villard 12-417 (Seibel 6468 x Subéreux) x Seibel 7053 (Chancellor). It was named after the municipality of Bougé-Chambalud in the Isère department in southeastern France. The name Chambourcin comes from the municipality of Bougé-Chambalud in the Isère department, where Joannes Seyve had a trial field. Synonyms include 26-205 Joannes Seyve, Chambourcine, Chamboursin, John Saym, Joannes Seyve 26-205, JS 26-205, Shambursen, and Zhoan Seiv 26-205. It contains genes from the species Vitis labrusca, Vitis lincecumii, Vitis rupestris, and Vitis vinifera. The crossing of the hybrid was carried out by Joannes Seyve (1900-1966) at the Seyve-Villard breeding operation. It was a crossing partner of the new breeds Regent and St. Vincent. Properties The medium to late ripening, high-yielding vine is resistant to both types of mildew and frost, but sensitive to drought and chlorosis. It is excellent for humid warm conditions and frosty winters. The variety produces dark-colored, aromatic red wines without Foxton despite Vitis labrusa genes. Cultivation areas After a temporary ban, it has been officially allowed in France again since 2008. Here it occupies 592 hectares of vineyard area, mainly along the Loire, with a strong declining trend (in the 1970s there were still 3,500 hectares). Further stocks exist in Madagascar, Romania (0.1 ha), and Switzerland (2.5 ha). Overseas, there are cultivation areas in Australia (41 ha), Canada, New Zealand (3 ha), South Africa (13 ha), and Vietnam, as well as in the US states of Arkansas, Illinois, Indiana, Michigan, Missouri, New York, North Carolina, Ohio, Pennsylvania, and Virginia (a total of 315 ha). In 2016, a total of 968 hectares of vineyard area were reported (Statistics Kym Anderson). Source: Wine Grapes / J. Robinson, J. Harding, J.
