Just two weeks after bringing you news of Stone Brewing Co.’s Xocoveza Extra Añejo, it looks like another version is in the works.

According to filings with the Alcohol and Tobacco Tax and Trade Bureau (TTB), the Escondido, Calif.-based brewery will not only be releasing Xocoveza Extra Añejo (12.2 percent ABV), but also another version that has been aged in oak bourbon barrels from Kentucky for seven months.

Xocoveza Charred is an 11 percent ABV stout brewed with U.S. pale, Maris Otter pale, black patent, coffee malt, chocolate malt and crystal malts, along with challenger and east kent golding hops. The beer also includes lactose, flaked oats, coffee, vanilla, Pasilla peppers, nutmeg, cinnamon and cocoa.

“Time spent in bourbon barrels gave an already complex beer even more complexity and flavor intensity, layering additional caramel-like and vanilla flavors on top of those already present,” reads the label.

When it was released early last year, the original Xocoveza mocha stout was based on the recipe of Chris Banker, who won the 2014 Stone Homebrew Competition. Like the yet to be officially announced Xocoveza Extra Añejo, the newest incarnation of Xocoveza will be released under Stone’s Quingenti Millilitre Series, a collection of experimental beers that Stone packages in 500ml bottles. Xocoveza Charred will be the third Quingenti Millilitre beer this year, after Fyodor’s Classic (13 percent ABV) was released in March and Xocoveza Extra Añejo, which has not been released.

According to the beer label, was brewed on Nov. 12, 2014 and will be bottled in July of this year in 500ml bottles. An email sent to the brewery for additional details was not immediately returned.
