According to labels filed with the Alcohol and Tobacco Tax and Trade Bureau (TTB), Modern Times Beer is working on releasing Mostra Tones, a 14.8 percent pastry stout brewed in collaboration with Mostra Coffee.

This San Diego-based brewery’s new release is a monster of a stout which features a blend of six of the brewery’s base beers: Monsters’ Park, Modem Tones, Mega Devil’s Teeth, Oblivion Ring, Dragon Mask, & Infinity Gauntlet. Once blended, the mélange was then aged in six different types of barrels: bourbon, Kentucky whiskey, rye whiskey, California brandy, port, and rum. It was then infused with Mostra Coffee Beans, Dominican cacao nibs, split Mexico, Veracruz, & Madagascar vanilla beans, toasted almonds, and toasted coconut.

The beer is set to be packaged and released in 750ml bottles.

An email sent to the brewery for additional information was not immediately returned.
