I brewed a batch of extract Caribou Slobber recently and had some judged in a local BJCP sanctioned competiton. I only scored a 25, mainly due to judges picking up on some Acetylhyde and a tiny bit of diacetyl which was a definite letdown as my other beers were in the mid 30s.
I’m curious as to what could have caused this as I kept my ferm temps in the mid to upper 60s, fermented in the primary for 21 days and secondary for 21 days. Bottle conditioned for 2 weeks and I believe the beer was judged around the 4 week mark in the bottle.
I’m wondering if this could be some sort of contamination issue or just a beer that isn’t maturing as fast as usual?
Has anyone else had a similar issue despite the long ferm periods? I’m kind of clueless as to what could have caused this…
