We got a pretty horrid efficiency. We believe the issue is a bad crush. We had to use the mill at the homebrew store.
|
|
After 1 month at 50, temperature was dropped to 35 in preparation for racking to secondary for lagering.
|
|
At 1 month in the fermenter, the beer tastes great. Maybe a little bit sweet.
