Here are some suggestions of good beers many have offered.

Belgian Beers
Try one of the Belgian offers that are usually available at Cole avenue and Spring Street:
Hoegaarden Witbier (the King of white beers) 5%alc.
Blanche de Bruges (white beer, which you are obviously supposed to have in a «grail» with a lemon. awesome)
Duvel (golden ale, absolutely amazing, the King of Belgian Beer, period. This is what people in Bruxelles drink) 10%alc.
Grimbergen (pretty darn sweet! abbey/trappist ale)
Lindeman's Lambic ale (flavored with cherries, peaches, etc...it's a highly unique beverage)
Commentary on the above: Hoegaarden > Blanche de Bruges. Duvel and Grimbergen are tasty. Lindeman's tastes very different from normal beers, but there is no essential difference in the method of brewing. For a nice selection of Belgians, try the Beverage Den on Rt. 7 in Bennington. They've got Orval, Chimay, Rochefort, Witkap Pater, Cantillon Gueuze, Saison Dupont, de Ranke xx Bitter, and some other stuff. However, they do not have Brugse Straffe Hendrik, which is unfortunate. For cheaper belgian style beers, Allagash, Unibroue, and Ommegang are all awesome.
Other Imported Beers
If you hate the Belgians (and, after all, who doesn't?), here are some other great imported brews:
Samuel Smith - Oatmeal Stout, Imperial Stout, Taddy Porter, Pale Ale, Nut Brown Ale, and Winter Welcome Ale. (UK)
Unibroue - Le Fin du Monde, Trois Pistoles, U2, Ephemere, Terrible and others (Canada)
Celebrator Doppelbock (Germany)
Spaten - Optimator Doppelbock, Oktoberfest, Pils, and Premium Lager (Germany)
Newcastle Ale (UK) - One of my favorite brown ales. For those who like a slightly sweet beer with a just-bitter-enough aftertaste. Yum.
Guinness Brewers (Dublin) - Guinness (Irish stout), Harp (Lager), Smithwicks (ale) are all excellent. If you like a black and tan, Gunness and Harp is where it all started.
Sol (Mexico) - A mild, agreeable blonde.
Domestic Beers
Craftbrewed/Microbrewed Beers
Stone Imperial Stout
Otter Creek is absolutely fantastic. The Vermont Lager is one of their "year-round" beers, and it's probably the smoothest tasting of the bunch. If you're looking for a little more kick, the Pale Ale (also a year-round) is one of the best I've ever had. For even more of a bitter aftertaste, try the seasonal Alpine Ale and the Extra Special Bitter (I don't particularly love them, but you might). Another interesting seasonal is their Middlebury Ale, which is chock-full of blueberry taste. It's a bit overwhelming at first, but it's worth picking up a six-pack to try it out.
BBC brews up some mean beers. Almost anything by them is great, though the Steel Rail Extra Pale Ale is debatable. Support local beer! The BBC Imperial Stout is easily one of the best Imperial stouts you can get anywhere.
Tröegs Brewing Co. from PA brews a wonderful American Pale Ale.
The Long Trail Ale Brewing Co. (near Killington, VT) brews some great beers, the Double Bag (dusseldorf altbier 6.7%) is excellent.
Macrobrewed Beers
Milwaulkee's Best, aka "The Beast." A great first beer to try and a Williams favorite. Excellent, full flavor, it's a real beer experience yet light enough to play Beirut or Flipcup with. Very well priced for such a great beer. It's especially enjoyable if you burn off your taste buds on any given night.
Sam Adams Boston Lager is one of the best domestic macrobrews out there.
Rolling Rock - Perhaps not deserving of the "good beer" title, but it's one of the most drinkable cheaper beers out there. A 30-pack will set you back about 20 bucks, and it isn't half terrible. (also light enough for Beirut or similar games)
Yuengling is a good macrobrew, though hard to find in the Northeast.
Sierra Nevada is an excellent beer which has gotten big enough to count as a macro. Try the Pale Ale, you won't regret it.
