As it was explained to me, these grapes must ripen, and then remain in the vine well into the winter. The process requires 3 days of 15 degree temperatures and the crush is done in an acclimated environment so the grapes remain frozen throughout. 
Grapes for Ice wine are something that in the last 10 years has only been harvested 5 times on the peninsula. It has become a sought after as a very sweet wine as the sugars are more concentrated because of the freezing process.
The Grey Hare Inn of Old Mission Peninsula, is one of many growing spots on the peninsula which grows grapes for ice wine. It is where this picture was taken. For more pictures in a very large zip file, Click HERE
