Of course there are. Wine grapes can be grown as far north as 50 degrees latitude, or the rough equivalent of Calgary, Alberta.
I was stationed in Germany for four years, lived in a Mosel River town by the name of Traben-Trarbach. My favorite winery, about a ten minute drive from my apartment is located in Briedel, latitude 50.02 degrees latitude.
Dozens of wineries in that area produce award winning wines every year. In fact, it's time for me to place another order with that winery. They ship to Texas, and I'm able to buy direct from them at less than half of retail.
I also noticed that Pampa, ID has two dozen wineries, located on the Snake River.
