The red grape variety (also Elmer Swenson 517) is a very complex interspecific new variety between Elmer Swenson 80(Minnesota 78 x Kendaia) x Villard Blanc. It contains genes from Vitis berlandieri, Vitis labrusca, Vitis riparia, Vitis rupestris and Vitis vinifera. The crossing of the hybrids was done by the US breeder Elmer Swenson (1913-2004) near Osceola (Wisconsin). The variety is grown in Canada (Quebec), as well as in the US Midwest. However, no stocks were recorded in 2010 (Kym Anderson).
