Main issue Ive found brewing at this volume (12ish AG batches) is keeping ingredients fresh. Think my brewing had improved massively over the last few months but using hops in single digit grams and bits of grain here and there means my most recent brews have tatsed a bit unexcitng. Stepping up...
I was really having trouble with this but found leaving my beer to bottle condition to 3-4 weeks, rather than 10-14 days really helped. Still need to be careful not to pour out the whole bottle though. Good job practice makes perfect
