The Rare Barrel Bellatrix
Aroma: “Blackberry is intense with a fair amount of acetic and a bit of ethyl acetate. There's a lot of oak and earthy wet hay behind that.”
Flavor: “The moderate acidity in the aroma is more prevalent in the flavor. A nice clean lactic sourness is predominant, but a touch of acetic makes the moderate juicy blackberry character really pop. The sourness lingers for a while, making this a beer to sip rather than heavily indulge. A nice Brett barnyard complexity and pleasant malt rises over time.”
Overall: “Great juicy blackberry and the barrel character is really nice. The sour complexity is nice, and there’s enough of it there to make you slow down and appreciate the beer.”
