Hey there! Fellow VT'er here. You're in luck - there's tons of great breweries here in vermont.
I'd recommend hill farmstead, and on your way back go through morrisville and hit up Rock Art (they just released a bourbon barrel aged barleywine). Keep driving on that road and, besides the beautiful scenery right now, you'll go through stowe and eventually find yourself in Waterbury (home of Heady Topper). It's worth a stop to the brewery, which typically will have heady for sale monday - thursday..friday is spotty...saturday is almost always a no go. Even if they don't have any for sale, you can grab a sample of it and take a look at the brewery. Go into Waterbury "downtown" ... this is where you can try all of the great VT beers. Blackback Pub and the Reservoir are my two favorite stops, but you can't go wrong with prohibition pig (old alchemist brewery building) either. All three are 6-9 bucks a pint, but you can try (on most days) at least 3 from hill farmstead, 2-3 from Lawson's finest liquids (another great vt brewer), and other locals from the state. If you're looking to bring home Lawsons beer..look for it at the Warren Store, Beverage Warehouse in winooski.
If you're heading to Burlington, try flatbread (home of zero gravity brewing), and certainly get out to Fiddlehead to try their (single) IPA as well as their other great beer! It's in Shelburne (about 25 minute drive from downtown Burlington down route 7 towards middlebury). It's also across from a Winery. If you're feeling more adventurous head to Bobcat cafe and brewery in Bristol...good beers to be had there. In downtown burlington you can hit up the farmhouse tap and grille (located inside an old mcdonalds, just off church street ... 6-9 bucks a pint). Keep driving into Winooski and hit up Mule Bar ($6-9). Then drive up to St. Albans and stop by 14th Star Brewing (open thurs night, friday night, and sunday morning). they have some decent offerings.
