I stopped in at The Collective Brewing Project in Fort Worth, Texas and enjoyed tasting their sour beers.  From Funky Thunder to Biere de Garde to Petite Golden Sour to Cup o’Beer to Suspicious Delicious.  They definitely have the sour beer thing going.  A wide variety of sour taste profiles.  I also tried the End of the Week Stout which was very tasty.  And with the addition of local cold brew coffee it was even tastier.  Great place to stop for a beer in town.
