Chambourcin is a French-American interspecific hybrid grape variety used for making wine. Its parentage is uncertain. The hybrid was produced by Joannes Seyve who often used Seibel hybrids produced in the 1860s. The grape has only been available since 1963; it has a good resistance to fungal disease, and is one of the parents of the new disease resistant variety, Regent, which is increasing in popularity among German grape growers. Chambourcin is considered a very productive grape with crop yields reported ranging from 11.1 tons per hectare to 17.3 tons per hectare in a study performed by Ohio State University.
