It only requires 100 chill hours, so basically it can be grown anywhere in the U.S. and many parts of Canada. The fruit quality is excellent, and usually ripen early among grape cultivars.

Now as you might have read, we are having some unusually warm daytime temperatures here in San Diego for December. My poor Suffolk Reds are confused, and sporting fruit buds as if it is spring!
