Heretic Brewing Company: Incubus Bourbon Barrel Aged Russian Imperial Stout

Official description from the brewery:
What is better than a big, rich, malty, roasty Imperial Stout? Imperial Stout aged in bourbon barrels for six months. Barrel aging not only adds vanilla, toast, bourbon, and other flavors, it mellows the beer, making it richer, smoother and even more delicious.
