Odd Side Ales has announced it will be releasing a somewhat different version of its Bourbon Barrel Mayan Mocha Stout on Día de los Muertos (Day of the Dead).

Inspired by Mexican hot chocolate, the beer is blended with cinnamon, nutmeg, Dutch chocolate coffee and habaneros, then aged in Colorado-based Breckenridge Distilleries bourbon barrels for eight months before being bottled. Only 580 cases were produced.

Although the regular version of the Mayan Mocha Stout has been around since 2012, the first incarnation aged in bourbon barrels was not released until December of last year. This year’s imperial version is quite a bit different, with an ABV of 9 percent compared to 6 percent for last years, although it will still be sold in 12-ounce bottles.

Bourbon Barrel Mayan Mocha Stout is being released in 12-ounce bottles ($5) at an event held at the Grand Haven, Mich. brewery on Oct. 31 with a very limited distribution after that in the state of Michigan.
