Picked up the Blood Orange Gose from Anderson Valley the other day. Good stuff. Was just down in SC recently - had the Westbrook IPA, but not the gose. Besides that and the Kirsch what else should a gose novice be checking out?
I think Westbrook only cans theirs from April or May-October or something like that. Probably why you missed it.
Anderson Valley also cans THe Kimmie, Yink and Holy Gose for the six months that it's not doing the Blood Orange.
Destihl cans a really good one (almost as good as Westbrook but not quite), but I don't think they ship here yet.
Off Color Troublesome is ok and can sometimes be found in VA and DC, but tastes more like a hefeweizen. Not very tart at all.
Union Craft just announced they're going to start canning theirs in May, but imo it's not in the same league as the others that have been mentioned.
One of the best I've had is Ritterguts, from Gemany. Though maybe I loved it because i had an overpriced serving on draft at Churchkey.
Rapp and Cigar City also make very good ones that are draft only if you're ever in the Tampa area.
