For NorCal, I'd say Anderson's Blood Orange Gose is pretty damn tasty and widely available. What are your go to's that you'd regularly expect to be at your local shop or higher end grocery store?
Tilquin quetsche, Boon marriage parfait, Rodenbach grand cru, Agree as well on the blood orange gose.
Picked up a case of this: Kirsch Gose Amazing. Lots of nice shelf sours finally starting to pop up that aren't too expensive! Although I have to agree with previous comments that some of the belgians are probably the best (but aren't cheap). You just can't go wrong with Duchesse De Bourgogne
My go-tos are Avery Raspberry Sour> Crooked Stave - just about anything Jolly Pumpkin Madrugada Obscura and Sorry to hear your V@S went bad
Great responses so far, tho I should clarify my original question: I'm interested in cheaper / higher volume sours. For instance, Bevmo sells 6ers of Blood Orange Gose for ~$10.99.
The process of making sours, especially in the lambic tradition, precludes cheap/large volume options for the most part. You're likely to find mostly Berliner weisses and goses that meet that criteria.
The Destihl Wild Sour series stuff is usually pretty darn good. Can be had for about that price (maybe a bit cheaper) around here.
I can't think of anything that's much better (or less expensive) than 750ml bottles of de Garde Bu Weisse for $5 and Petit Desay for $6.
OOOH that changes it for me then. When I think "go-to" I don't always think cheap. Does Blue Sunday fit? I think $8 for the bomber Echo the gose comment: AV Blood Orange, Distihl, etc. Lilikoi Kepolo is a winner at ~$10 a 4pack and I'm not usually a fan of the witbier style. Solid brew
