This is part of their Leviathan series. I have never seen this in a bottle but was highly fortunate to find it on tap at Draft Restaurant in downtown Raleigh this week. We had a BOGO free coupon for entrees and, on Monday nights, all pints are $3. This ended up being "only" a 10 ounce serving in a goblet but most high gravity brews end up being 8-10 ounce portions due to the higher ABV.
It was served a bit too cold but after warming a bit, I found this to be a fascinating and complex brew. There was a small head topping a deep mahogany colored brew that smelled and tasted of dried raisins, figs, dates and dark rum. The dark Belgian candi sugar added confers a bit of sweetness to the already very malty flavor. The texture is almost silky. I'd guess the IBU to be rather low, perhaps 20-30 and the ABV is a potent 11.75%. I sipped this a bit before my gourmet burger arrived and finished it after dinner for my "dessert." Brews this complex and potent make very fine "after dinner drinks." I'd love to find a 4 pack of this to compare with the draft variety, in addition to storing a bottle or two for a while (2-3 years even) and then tasting what "cellaring" or "aging" has done for its complexity.
