The red grape variety is a complex interspecific new breeding between Elmer Swenson 2-12-27 (Elmer Swenson 5-14 x Swenson Red) x St. Croix. Synonyms are ES 4-7-25 and Elmer Swenson 4-7-25. It contains genes from eight vine species, namely Vitis aestivalis, Vitis berlandieri, Vitis cinerea, Vitis labrusca, Vitis lincecumii, Vitis riparia, Vitis rupestris and Vitis vinifera. The crossing of the hybrids was done by the American breeder Elmer Swenson (1913-2004) near Osceola (US state of Wisconsin). The frost hardy vine is grown in kjleine stands in Canada (Quebec). In 2016, 1.4 hectares of vineyard area were designated (statistics Kym Anderson).
