I'm back with the same darn problem. I'm getting poor efficiency, and not hitting my targets. I'm four brews into my new eBIAB system and I cannot figure out what I'm doing wrong. Can you please help me identify the problem?
Mosaic Blonde recipe looks like this:
10 Lbs. Golden Promise, 8 oz. White Wheat, 4 oz Special B, 4 oz Acid Malt. Fine Crush from LHBS
.5 oz Hellertauer Blanc (60 min) 1 oz Mosaic (5 min) 1.5 oz Mosaic (whirlpool)
Built my water with a balance yellow profile, estimated 5.38 pH (Bru 'n Water)
152 degree mash temp for 60 min. Boil for 60 min.
Pitched 2 packets US-05 - fermented 7 days at 68 degrees. 24 Hour diacetyl rest at 72 degrees.
Measured this:
Post mash gravity: 9.4 Brix
Boil volume: 8.05 Gallons
Post boil gravity: 12.2 Brix
Post boil Vol: 6.47 gallons
Final Gravity: 6.2 Brix (1.04 correction factor)
ABV: 5.01%
Beersmith says my measured efficiency is 62.5% - and I'm off my ABV target by almost a full 1%
I'm guessing it's something in my process, but I can't identify it. I didn't recirculate during the mash this time - not until the very end at least. I set it at 152, kept it covered, and let the inkbird control it for the 60 minutes. The kettle is well insulated. Stirred well at 60 minutes, recirculated for 5-10 minutes, then pulled the bag. The bag was drained and squeezed thoroughly, and everything was added back into the boil kettle.
I'm feeling like my boil volume is off, and maybe that's diluting the beer?
I noticed again that (even thought the inkbird was set to 152) the top of the mash was only about 149-150 degrees. I was hoping nor recirculating would solve that problem, but it didn't. Could that be the culprit?
Please help. Yeah, it's beer and it'll drink, but I want it to be better.
Can you help me identify what might be going wrong?
Thanks,
