Athens, Ga.-based Creature Comforts Brewing Co. recently announced the second release of Existence.

Existence is a bourbon barrel-aged imperial stout with an ABV of 11.8 percent. that was brewed shortly after Creature Comforts opened in 2014. This is the second time the stout has been sold in bottles, after the first release earlier this year.

The base beer was aged for 19 months in Willet bourbon barrels and is the second imperial stout to come from Creature Comforts’ Wood Cellar. The beer was designed to age and develop over time, and the end product is the imperial stout with “notes of oak, vanilla, dark chocolate, subtle cherry and bourbon.”

Existence will be available in 750ml bottles and in extremely limited supply. It will be released through a ticketed brewery tour on May 21. Tickets will be available through starting May 13 at 1 p.m.
