Perrin Brewing Company: Big Griz

Official description from the brewery:
This bourbon barrel imperial brown ale was crafted with specialty malts and unique hops from all over the world. Undertones of fresh American oak and vanilla carry through with not-so-subtle hints of warm maple syrup and melted caramel sweetness that book end this uncommon monstrosity of a beer. Be careful when our Big Griz gets ahold of you........
