Which American brewery makes the best sours?

Russian River.

 

Me thinks every post will say Russian River

 

New Belgium. They're all reasonably priced and easily obtained. Plus Le Terroir is still my favorite sour, and that includes the few I've had from the likes of RR and Cantillon.

 

Cascade...hands down. Russian River's sours are good, but goddamn every time I have Cascade, I'm blown away

 

Russian River is good, Cascade can be great, and i actually prefer them overall to RR, but I am going to go out on a limb, something about Upright always impresses me. They are just solid and usually have great prices.

 

Russian River, even if they only made Beatification and Consecration. My two favorite sours

 

Just to keep it going I'll chime in too. Russian River.

 

Cascade (because I am the biggest homer on this entire forum) and then Russian River.

 

While I do love Russian River (especially Beatification), I think I'm going to say Allagash - specifically the Coolship series. Really, really great stuff.

 

Pisgah.
Oh wait.... You mean intentionally?

 

I'm gonna go with Cascade, even though I love Russian River. I usually get a lot more excited about their sour releases than I do Russian Rivers, probably due to the variety they have.

 

RR is my number 2, tied with St Somewhere... Jolly Pumpkin is by far number 1 in my book.

 

Need to offer some love to Allagash

 

Though Russian River knows how to brew sours with the best of them, I would much rather have a cellar full of Cascade sours than Russian River sours. I love me some Cascade Blueberry!

 

no love for the bruery? Mother Funker and fimishmish were fantastic...

 

I would say Russian River, but Lost Abbey and the Bruery make some great ones as well, especially Cable Car. I've only had Vlad the Imp Aler from Cascade, so I don't really feel that I can say they're the best with me only having tried one. I do have a bottle of the Vine though, so my opinion may change when I have that.

 

I am in agreement with those of you that said Cascade. Though, I love the Cisco Woods series of sours here in MA.

 

Have Tried (in no particular order):
Bruery (ToD, Oude Tart, Flemishmish, GFAR)
RR (only Supplication so far)
Jolly Pumpkin
New Holland Blue Sunday is (to my knowledge) NH's only sour but it's awesome
Stillwater has a few and they're damn good, though they mostly make farmhouse
Cisco Woods

Have Not Tried:
Cascade
Upright
Allagash Coolship (would not consider most other Allagash sours)
Lost Abbey sours

 

Avery has been cranking out some amazing sours. Some hard to get or are only served at the brewery but freaking awesome to say the least. Their lineup at sour fest was epic.
