Cascade is a
Seibel grape, being produced from a crossing of
Seibel 7042 and
Gloire de Seibel by the French viticulturist Albert Seibel in the early 1930s. The exact reasoning behind the name is unclear, with some winegrowers speculating that the name came from the way that the highly productive vine would have fruit "cascading off the vine" like a waterfall even from
water sprouts and
suckers. Cascade is considered an interspecific "complex hybrid", meaning that within its pedigree are grape varieties from several species of the
Vitis genus. Taken together the pedigree of Cascade includes varieties from the
Vitis vinifera,
Vitis labrusca,
Vitis rupestris,
Vitis rotundifolia and
Vitis lincecumii species. Seibel 7042 is a
crossing of Seibel 5351 and Seibel 6268. Gloire de Seibel is a cross of Seibel 867 and Seibel 452. From these parent and grandparent varieties, Cascade is descended from
Concord,
Chasselas Musqué and the
Vitis vinifera teinturier grape
Alicante Bouschet (great-grandparents to Seibel 5351). Cascade also has extended relations with another
vinifera teinturier
Alicante Ganzin (grandparent to Seibel 452) and the
Munson grape (great-grandparent to Seibel 452). The
phylloxera-resistance
rootstock variety
Rupestris du Lot is also related to Cascade as a grandparent variety to Seibel 452.
Relationship to other grapes In Canada, Cascade was crossed with the white
Villard grape Seyve-Villard at the
University of Guelph Horticultural Research Institute of Ontario to produce the white wine grape
L'Acadie blanc. ==Viticulture==
