Not technically new to brewing but I think it's time to get some opinions. I've brewed around 10 batches beginning with buckets and moving on to the glass carboys. I'm currently using a robobrew V3 and a fermzilla all rounder. I just finished a lutra kveik pseudo lager. Volume and gravity were as advertised. OG 1.052 and FG 1.010. Fermented at 12 psi at around 76 degree ambient temp. Fermentation was done in 3 days but I left it in the fermenter for another 5 days to clean up. Closed transferred it to a keg and carbonated. My question is why do all of my batches have that green apple acetaldehyde flavor no matter how long I leave it in the fermenter or do a diacetyl rest? Maybe it's me but they all have that flavor. Help!
