GRAND RAPIDS, MI - Fans of barrel-aged beers have another brew to try while visiting Founders taprooms in Grand Rapids and Detroit.

Panther Cub will be available exclusively in the brewery's Detroit and Grand Rapids taprooms in 6-pack bottles and on draft beginning Dec. 1. It is the fourth release in the taproom-only Mothership Series and the first barrel-aged release of the series.

"What would a Mothership Series be without a quintessential barrel-aged release to get folks excited?" said Brewmaster Jeremy Kosmicki.

"It's been years since we last released Panther Cub and we're pumped to bring this barrel-aged vanilla porter goodness back to our taps and, for the first time, bottles. Get it while you can."

Panther Cub has been featured in the taproom only a handful of times, but not for several years. This is also the first time it will be bottled.

The alcohol by volume of the beer has yet to be determined, but it was developed after "reflecting on youthful dalliances of yore," according to a news release.

Panther Cub is a small porter aged in a combo of BLIS maple syrup bourbon barrels and regular bourbon barrels.

The brew has been aging for more than two years with whole vanilla beans. Beer-lovers can expect maple and vanilla notes with surprisingly-deep character.

Panther Cub will have a suggested retail price of $14.99/6-pack The Mothership Series also includes: Red's Rye IPA, Sleeper Cell and MF Donkey Stout.
