The red grape variety (breeding no. Vineland 49-431) is an interspecific new variety between Vineland 370-628 (Lomanto x Seneca) x Seibel 10-878 (Chelois). It must not be confused with the St Vincent variety. It contains genes from Vitis aestivalis, Vitis champinii, Vitis cinerea, Vitis labrusca, Vitis lincecumii, Vitis rupestris and Vitis vinifera. The hybrid was crossed in 1947 by grower O. A. Bradt in Ontario-Canada.

The late-maturing, high-yielding vine is very resistant to frost down to minus 26 °Celsius, but is susceptible to powdery mildew. It produces dark-coloured, rather low-tannin red wines with aromas of cherries and plums. The variety is mainly used in cuvées as a colouring grape ( Teinturier ).

If I were to rate websites, you would deserve the highest rating. It is rare to come across websites that provide such a large amount of data and are still so intuitive to use. Respect for the lovingly researched and informatively prepared encyclopedia. Keep it up!
