Yes, but I asked for one of their stouts in a growler once and was told they don't put stouts in growlers.
They do. NH Law stipulates that they must fill only Pbrew growlers, so bring your own, or you'll need to buy onsite (sometimes they are sold out so I'd call ahead). They also sell bottles for a couple of the recent brews in the retail store. You can see what's on draft and in bottles on their facebook page (sorry I'm too lazy to link it here).
Indeed - but I think NH requires you to use brewery-branded growlers (meaning you have to pay the deposit for one of theirs). Correct me if I'm wrong on that, interwebs.
Awesome thanks. I'll be at black birch in Kittery and though I Should hop over the line to see what's good over there
