After collaborating on a beer last year, Prairie Artisan Ales and Omnipollo are at it again.

According to Henok Fentie, owner of the Sweden-based brewery Omnipollo, Abundantia is a 12 percent ABV imperial milk stout that is brewed with salted caramel sauce. The release is a collaboration between Tulsa, Okla.-based Prairie Artisan Ales and Omnipollo, and was brewed at Krebs Brewing Co. on March 12.  Omnipollo and Prairie have collaborated once before on a saison named Potlatch (7 percent ABV), which was released in 2014. That beer was brewed in two different locations: Krebs Brewing Co. and De ‘proef’ brouwerij in Belgium.

Prairie Omniprairie

Interestingly, the Alcohol and Tobacco Tax and Trade Bureau (TTB) just approved a keg label for a new Prairie beer named Omniprairie, which is labeled as a 10 percent ABV milk stout.

According to Fentie, Abundantia will be will be a draft-only release available in both the U.S. and the EU, and will be released “in a couple of weeks.”

Prairie Artisan Ales did not respond to multiple requests seeking comment on the project.
