Chicago’s Goose Island Beer Co. will roll out several new permutations of its famous whiskey-kicked Bourbon County Stout, including coffee, orange, vanilla, blueberry, rye barrel-aged, dry-hopped, and more, the brewery announced. This follows the trend of breweries — especially those from the Midwest and Colorado — brewing endless spinoffs of their flagship imperial stouts.

Founders Canadian Breakfast Stout, a whiskey-aged version of their popular Breakfast Stout, was Churchkey‘s second-fastest-selling beer, after Bell’s Hopslam. And Denver’s Great Divide has been futzing with their big-boy beer for five years, putting their Yeti Imperial Stout through oak barrels and infusing it with vanilla, chocolate, and espresso.

This rush of new flavors is exciting, but you’d best prepare yourself and gather some dark-beer-loving friends — Yeti and Bourbon County Stout hover between 9 and 13 percent abv, so you’re going to want folks to split those bottles with.
