So I've got a Black IIPA that's not fermented well, and i trying to figure out what to do. I've repitched with a second yeast packet (even though I know I should've made a starter), and it's been 4 weeks since brew day. it's a 2.5 gallon batch and the grain bill is:
6 lbs 2 row
1 lb Munich
.75 lb Crystal 60
.5 lb German Carafa III
pitched originally with S-05 (the whole packet according to Mr. Malty calculator) and repitched with a packet of S-04 just because i was pissed off when it didn't ferment down well (at the 2 week mark).
Mashed at 154 for 60 minutes, and hit my #s. Aerated with the 'shake' method since there was a lot of headspace in the carboy (half batch in a 6 gallon carboy). OG was 1.085 and i'm sitting at 1.034 right now. That gets me right at about 57% attenuation, and 6.7% ABV for the recipe I used, according to BeerAlcehmy. I'll be dry hopping in secondary, but the question is:
- should I transfer to secondary, make a starter and pitch it in there?
- accept poor attenuation and just go with it and know it's not going to be the best (reads: driest) beer ever
- repitch onto a yeast cake after my next brew is finished fermenting, which won't be for a few weeks.
- ditch the whole batch and start something else
its a 2.5 gallon batch, so it's not the biggest investment of time/money if it's not worth keeping/bottling.
On the question of thermometer accuracy, it reads 32 in ice water and about 210 in boiling water...so i'd call that pretty good. have since bought the O2 regulator/stone system and will be infusing pure 02 in my next beer...i've been struggling with poor attenuation since converting to AG 3 batches ago.
