This is why I'm constantly asking: why aren't we planting vineyards in the Wasatch Front? Silicon Slopes didn't work out but can we at least farm some effing grapes?
I don't think there are good or bad wine growing regions as much as there are places where people have figured out how to make good wines. The Finger Lakes had a bad reputation once but people figured out Rieslings and some more affordable whites that reputation changed. More recently it was famous for soda-pop sweet wines like Red Cat but I've had some dry reds lately that weren't as bad as what I had 20 years ago.
Despite there being many great breweries in that region, most people shy away (initially) from a state run by a prohibition-style religion. Probably illogical, but definitely real in my experience.
