Fans of peanut butter and chocolate in their beers should be very happy with some new cans being released by Great Notion Brewing this weekend.

The Portland, Ore.-based brewery has announced it is releasing cans of its Peanut Brother, a 9 percent ABV imperial milk stout conditioned on peanut butter and raw chocolate. The stout has been a draft-only option at the brewery since 2016, but this is the first time it has been canned.

According to a post on Great Notion’s Facebook page, the newest incarnation of Peanut Brother will be packaged in four-packs of 16-ounce cans with allocations determined by the number of people who attend the release on June 30 at the brewery.
