Not sure if this should be in the yeast forum or here, let me know if I need to move it. About 2 months ago I brewed my first all grain.
I did a Nut Brown kit from Northern Brewer with dry Danstar Nottingham Ale Yeast. Haven't used dry yeast in a long time and just rehydrated them as per instruction on the packet, didn't do a starter. Hit all the numbers (OG 1.045, FG 1.011) and transferred to a secondary after 1 week. Usually don't use a secondary and leave in the primary 3-4 weeks and I'm not really sure why I did this time, I think just bored one day. After 3 weeks in the secondary I kegged, cooled, then carbonated for 2 weeks. First pour tasted like wet grass mixed with dirty socks and was undrinkable.
The only variant during my brewing process was not hitting 170 F right away during the sparge and having to drain, heat up the wort, and add back in.
I'm 90% sure it is acetaldehyde but I didn't know if my recirculation during the sparge or another factor would have added the off flavors? If it is acetaldehyde will it settle out even though it is already in a keg, cold, and carbonated? My understanding was that warmer temperatures were better.
