Just a venting post here. I am very disappointed in myself.
I brewed what I call a "session ale" with S04 and decided to keg after 10 days since the yeast had dropped clear and it appeared to have a good, robust fermentation between 62-66F. I usually let it sit for 14-21 days but rushed it due to lack of homebrew. I did not look at the hydrometer reading until after kegging was done. The beer was super clear and there was a compact yeast cake at the bottom of the bucket.
There is a possibility that it was done but it finished at 1.016 (65% attenuation) instead of 1.011 which was anticipated. I mashed at 158F for the first time but I doubt it would have such a large impact. If I would have had the patience I would have taken a hydrometer reading while it was still in the fermenter, roused the yeast, and warmed it up. I could have transferred the keg back to fermenter but honestly did not want to deal with it.
The thing that make me angry is I don't know if it was done or not. This is a beer that I am trying to develop as a regular so results of this batch will likely be inconclusive due to the high FG and lower ABV.
ALWAYS TAKE HYDROMETER READINGS BEFORE PACKAGING YOUR BEER!! I know this but I still let impatience get the best of me. It is funny how much of an amateur I sill am after years of brewing...
