There tends to be a very large variety. In my city, there's about 3-4 local breweries that are so appealing they're sold at almost every restaurant in a 60 mile radius, and do quite well. On top of that, you have 50-100 eclectic small breweries and you'll find 3-10 on each restaurant menus. Then, if you go to a BWL store, there's almost as many beer options as there are varieties of wine.
I live in North Carolina, which you may have learned in history was a heavy Tobacco state during the colonial period. As tobacco has crashed over the past hundred years, it's been replaced with wineries and beer. There's a very large selection in my state, but I can't speak specifically for other states.
