One of Odell Brewing Co.’s most popular seasonal releases now has a big brother.

The Fort Collins, Colo.-based brewery has released Barrel-Aged Mountain Standard, a 10.6 percent ABV double IPA brewed with American hops and aged in bourbon barrels for over a year. As the name implies, the new beer uses the brewery’s Mountain Standard Black IPA (8.1 percent ABV) as its base.

“Barrels and time can yield some amazing changes to the character of a bold beer like Mountain Standard,” said Bill Beymer, head brewer at Odell, in a press release. “The oak has definitely performed some magic here. The assertive hop bitterness has made way for incredible flavors of sweet chocolate, dried figs, toffee, vanilla and caramel.”

According to a press release, Barrel-Aged Mountain Standard is packaged in 12-ounce bottles and is shipping “in very limited quantities” across Odell’s 14-state distribution footprint now.
