...that you're going to have to dump two batches of beer.
So last month I did a double batch brew day. Back to back. Ended up being about 11 hours with BIAB.
The first batch I did was a Two-Hearted clone. I mashed in normally with 170 degree strike water and cooling down to 155ish. I got it down to about 157, set my timer, and walked away. I came back about 45 minutes later and the temp read 180!!! I don't know if I left the flame on or what, but I managed to get 94% efficiency on it and a SG about 20 points high. I boiled, pitched my US05, and hoped for the best.
My second batch was a DFH 60 "clone". I don't recall having many problems with this one except my mash temp (again!) but this one was within the normal range. 83% efficiency so I was probably a bit high. Pitched a 1.6L starter of WLP001 for this one.
If I had to guess - this next part is where I screwed up. Due to some renovation my dad was doing in the garage, I had to ferment inside in my room. I used my swamp cooler and changed out frozen bottles of water twice a day. I had lots of activity the first three days , almost a disturbing amount. I think my fermentation temps were very high. The Two Hearted clone finished at 1.012 and the DFH petered out at 1.022.
So I went to keg them...carbed them up and...they taste horrible. Lots of sickly sweetness, diacetyl, and fruity off-flavors.
Out if frustration, I turned off my kegerator, closed the gas, and decided to write this before I go and dump them. It sucks, but it showed me major flaws in my process:
1) Watch that mash temp!
2) Watch that fermentation temp!
3) Calibrate my tools.
So, unless anyone has a better idea...I think these batches are going down the sink later today...
