I was in Vermont in March and can personally vouch for Vermont Brew Pub and The Alchemist. Both brewed great beer, but the food at the Alchemist was a lot better.
The friends we were with also wanted to take us to American Flatbread
in Burlington but the weather was awful so we didn't have time. They said the beer is pretty good, and the flatbread pizzas are very good.
You may want to try to make it to Trout River Brewery
and Long Trail Brewing Co.
Both make solid IPAs and their other beers may not rank high on the beer sites but are solid. While there I picked up McNiel's Old Ringworm
and a Rock Art Hells Bock
and greatly enjoyed both beers. However, neither myself nor my friend have been to the actual brewing locations or know what the rest of their lineups are like.
