The white grape variety (also GM 318-57) is an interspecific new breeding between Riesling x Chancellor. It contains genes from Vitis labrusca, Vitis lincecumii, Vitis rupestris and Vitis vinifera. The hybrid was crossed in 1957 at the Geisenheim Research Institute (Rheingau). The early ripening vine is resistant to powdery mildew, but susceptible to downy mildew. It produces flowery white wines with a discreet foxtone, which is why it did not establish itself in Germany. It is grown in Canada in the areas of Nova Scotia and Quebec. In 2016, 14 hectares of vineyards were designated here (Kym Anderson statistics). A small stand is also said to exist in the US state of New York.

The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.
