Pretty sure Heady Topper is available year round in Vermont. Heck I can get it here in SE Pa throughout the year. It's good, was a trailblazer before the NE IPA craze, I think that it's not even the Alchemist's best beer. Hill Farmstead is better though...Lawson's Finest Liquids Sip of Sunshine and Double Sunshine are really good as well. .....Fiddleheads.., so much in VT.
We got a boatload of fantastic breweries in my corner of Pa now, i feel there are a few that are almost on that level. Hidden River and Tired Hands are two that come to mind.
