Ehrenfelser is a white wine grape variety of German origin. It was created by Dr. Heinrich Birk (1898-1973) at the Geisenheim Grape Breeding Institute in 1929, by crossing Riesling with what was thought at the time to be Silvaner, but DNA markers have since indicated it was the Alsace variety Knipperlé.
Ehrenfelser was first grown primarily in the Palatinate and Rheinhessen regions in Germany, however as is the case with most white German "new crosses", plantings within Germany have decreased considerably in recent years. In 2006, only 112 hectares (280 acres) of plantings remained, down from 255 hectares (630 acres) in 1999.
Outside Germany, Ehrenfelser has found some success mainly in Canada, in the Okanagan Valley of British Columbia. Wineries including Cedar Creek, Lake Breeze, Gray Monk, Gehringer Brothers, Mount Boucherie, Quails' Gate and Summerhill make both still and ice wine styles. There have also been smaller plantings in Washington state and Canterbury, New Zealand. The grape tends to ripen earlier and produce higher yields than Riesling.
