Have you asked yourself "Can I grow wine grapes in my climate?". The varieties here are all extremely hardy. They are great in zones 3 through 7. Are your winter temperatures below -40 degrees? Probably not. So the answer is yes you can grow high quality grapes in your area.
The photos below are of a visit to our grape grower in the middle of April. It is a beautiful place and our relationship with them is one we hope to have for many years.
