Fool me twice. Sour, vinegar-like, burnt sugar/caramel. Buffalo Trace barrels used, we preteneded the first time that it was a wine barrel and we could excuse the taste, or something went wrong, but now I have to assume this flavor is by design.

Either this was wine-barreled or Big Block's barrels are infected. Given I've just tried their plain scotch ale and with my memory of both the plain RIS and barrel-aged Scotch Ale, the barrel-aged beers come out extremely sour and funky, just a bit more than Bellevue's similar-tasting results. Fine if you imagine wine, terrible if you imagine bourbon.
