There have been more than 30 incarnations of Cycle Brewing’s Rare DOS since it was first released in 2013, but even with all of those, an upcoming version is still unique.

The new beer is DOS Double Barrel, a imperial stout aged in bourbon barrels before then being aged again in cinnamon bourbon barrels. The stout uses the St. Petersburg, Fla.-based brewery’s Rare DOS imperial stout—which stands for Doug’s Original Stout—as its base.

According to a label filed with the Alcohol and Tobacco Tax and Trade Bureau (TTB), Rare DOS Double Barrel will be packaged in 22-ounce bottles. An message sent to the brewery for additional information was not immediately returned.
