In brewing, BBL is the notation for “barrel,” a unit of measurement equal to 31 gallons. This is not to be confused with an oak barrel, which typically holds nearly two BBLs of beer. Still with us? Great. A special blend of our bourbon barrel aged imperial stout with our bourbon barrel aged sour stout, plus an addition of juicy blueberries, Blue BBLs finishes with incredibly vinous tones. The acidity from the sour stout matches perfectly with the sweet malt character of the imperial stout and the fruity tannins from the berries round everything together. Notes of red wine, blueberry skins, toffee and roasted oak. A fine addition to the line up of Hoarders Society exclusive ales.
