The white grape variety (also Aldemina, ES 6-16-30) is a complex interspecific new breeding between Elmer Swenson 2-3-17 (ES 283 x ES 193) x Elmer Swenson 35 (Minnesota 78 x Dunkirk). Among others, the varieties Cayuga White, Concord, Luglienga Bianca and Seyval Blanc were involved. Genes of Vitis labrusca, Vitis lincecumii, Vitis riparia, Vitis rupestris and Vitis vinifera are included. The hybrid was crossed in the mid-1980s in the USA by Elmer Swenson (1913-2004) on his farm near Osceola in Wisconsin. The early-maturing, high-yielding vine is resistant to frost and diseases in general, but tends to split berries during the ripening phase. It yields low-acid white wines without foxtone with tropical fruit aromas. The variety is grown in Canada (Quebec), where five hectares were designated in 2016 (Kym Anderson statistics). It is also used in Finland as table grape in greenhouses.

Serious sources on the internet are rare - and Wine lexicon from wein.plus is one such source. When researching for my articles, I regularly consult the wein.plus encyclopaedia. There I get reliable and detailed information.
