Upland Brewing Co. and Prairie Artisan Ales have joined forces on a new beer.

Cursed Kettles is a sour ale aged in both wine and bourbon oak barrels for three months and conditioned on black cherries and figs. The base beer is kettle soured with lactobacillus from Prairie before bing fermented with 100 percent brettanomyces.

“Both locations will be brewing a different recipe, but using the same processes,” reads a post on Prairie’s website describing the beer. “The combined efforts will create a kettle soured beer, with Brett primary fermentation, aged in barrels and fruited at the end.”
