On tap at Corporate Ladder, pours black, tiny beige head. Aroma is extremely rich and complex, with intense bourbon barrels, brown sugar, molasses, some dark dried fruits, and toffee. Flavour is somewhat tart (not infected), with intensely deep bourbon barrel presence, tart-ish dark dried fruits, toffee, brown sugar, and a hint of roast. Great barrel presence, good base malts, but not sure about the tartness. This is clearly remarkably done, but what’s the deal with that tartness? Could be world-class without it. As is, just excellent.
