Rodenbach Grand Cru

Its a toss between JWakefield Cuvee de Wakefield and Jester King Atrial for me. Im getting shakes thinking about them.

 

Tell Tale Tart by Boulevard.
Also, Love Child #6.

 

Gueuze Tilquin.

Abbaye de Saint Bon-Chien.

Jolly Pumpkin Fuego del Otono. Oro de Calabaza is also pretty tasty.

Crooked Stave puts out some darn good stuff, too. Surette is delicious.

 

New Glarus - anything sour
Selin's Grove Framboise
Love Child #5
Cantillon Lou Pepe
Hanssens Oude Kriek
Lindeman's Gueuze Cuvee Rene
Bruery Oude Tart

Pretty much all the Goses and Berliner Weisse's I've had would come after that list. I love them but they don't stand out because of their sublety - which is one of the things I love most about them. (Side note: I just checked and never would have guessed I've had 18 different Goses or 14 different Berliners...proof I really do like the styles!)

Most of the sour beers I've had from Bullfrog have been fantastic, and unusual as well.

 

The um... One's with fruit aged in barrels...

La Fosse

Even though it's kettle soured (THE HORROR), Union's 3rd Stone apricot sour was jawdroppingly good.

 

I've only had one kvass, but it was lacto-fermented and tasted like straight up pickle juice. Any particular reason you wouldn't consider them sour?

 

Ommegang Rosetta.

I would drink it on a boat, with a goat, on a train , on a plane.

 

LOVE Grimm Telekinesis and Psychokinesis. Also really enjoyed Grimm Super Going and Echoplex. Purple Prose was great too! Enjoyed Rainbow Dome too.

Trinity 7 Day Sour
Peekskill LemPbeek Batch 1

Unless the OP is requesting a specific process, anything overly tart should likely count.

 

Boulevard Saison Brett must be mentioned but some great new comers are:
Lake Effect Oud Bruin
Penrose BA Outlier
Penrose Wild 18
Mikerphone Travelin' Man

In summary, Chicago's wild ale game is on point

 

Kvass is sweet, not sour. And it's not beer. http://russiapedia.rt.com/of-russian-origin/kvas/

 

I would hesitate to refer to Saison-Brett as sour. We inoculate with brettanomyces at bottling/racking which results in more earthy/funky flavor. I think if someone orders Saison-Brett expecting it to be sour, they're going to be very disappointed.

Haven't ventured deeply into the world of sours.
Allagash Resurgum, Allagash Golden Brett and Petrus Old Ale are my fav so far
