My craft beer-loving husband really likes Beveridge in Wolfeboro. I know it isn't one of the towns you listed, but I thought I'd throw it in in case you were passing through one day.

Very close by (a quick walk around the corner) is the Lone Wolfe Brewing Co., where you can get a flight, pint, or growler.

Also, if you're ever in the Alton Bay area, Johnson's Marketplace (it's actually in New Durham, but about 5 mins from the Alton circle) is good, as well.
