According to a label filed with the Alcohol and Tobacco Tax and Trade Bureau (TTB), Oskar Blues Brewery and 3 Sons Brewing Co. are teaming up for Swiss Guard, a 12.5 percent ABV imperial stout aged in port barrels. The stout is also being conditioned on both peanut flour and raspberry puree before being packaged in 12-ounce cans.

An email sent to the brewery for additional information was not immediately returned.
