Prairie Artisan Ales’ Christmas Bomb! is back, but with some significant changes.

The 2015 version of the imperial stout remains at 13 percent ABV and still uses the brewery’s Bomb! as its base, but has replaced the nutmeg and ginger that was used in last year’s version with more cinnamon bark. Christmas Bomb! was released for the first time in November of last year.

“We wanted to rework the spices a bit so it doesn’t have the nutmeg and ginger that last years had,” Prairie owner Wes Morrison said in post on the brewery’s Facebook page. “This year we ramped up the cinnamon and I think you’ll be happy. ”

According to a post on the brewery’s website, Christmas Bomb! is packaged in 12-ounce bottles and will start hitting retailer’s shelves “this week and next.”
