At first I thought I'd burned my palate out on the Emelisse (and I probably did), but no, I think this beer is probably genuinely gross. You can tell that the butterfinger is there, but the flavor is musty, lumpy and out of sorts in all kinds of ways. No harmony at all.
I have a really hard time quantifying how bad this beer was. It wasn't gross, exactly, but it had so many disparate flavors in it that came together in a way that wasn't good either. Dark Belgian base with stonefruit and smoke, with some strangeness in the spice profile and the visual appeal of chaw spit. Somewhat flat carbonation.
This reminds me of the "healthy vinegar" drinks my Korean mother is always trying to get me to drink, but overall? It was... okay. I'd like to try more in the style, but hopefully they're better than this. The bourbon and oak was detectable, but not quite strong enough, mixed with a little Belgian yeast.
The fresh pumpkin fragrance was really promising, vegetal and believable, but the flavor started weird and kept getting weirder. I'm not convinced pumpkin goes well with Belgian yeast, but it definitely didn't fit as it transitioned through medicinal flavors to a sour finish. The weirdness started out as appealing but that wore off very quickly.
Bottle numbered 19 of 150. A smooth, pleasant, medium-roasty stout with a nice chocolate fragrance and coffee sheen on the flavor. Slight rear alcohol kick that dissipates very cleanly.
