Brattleboro is close by and have a few breweries. Please note, they are more restaurant than brewery. I don't think any of these actually have something to tour. Out of all of them, I think that Whetstone is the best!
Take a little stroll down the street to Phelps Pub at Grafton Inn. The bartender Laura is great! Thursday night is generally Burger & Brew for $12. Live music on the weekends. Check the website to see if they are open.
