This grape has a particularly notable feature — it is frost resistant. Ehrenfelser was bred in 1929 by crossing Riesling and Knipperlé (an Alsace white grape variety). The name is derived from the ruin Ehrenfels near Rüdesheim in Germany. Originally grown there, it has found success in the Okanagan Valley of British Columbia due to its ability to thrive in cooler climates. It can also be found in smaller plantings in New Zealand and Washington state in the United States.
