Well, bottled this today. Shooting for about 2.5 vols.
My batch had a slightly higher OG than I was shooting for (ended up at 1.069) and attenuated nicely down to 1.016. The taste I had a bottling was... okay. Very grain-forward, kind of sharp (ABV is around 7%). I get some diacetyl and maybe a bit of cooked veggie/DMS kind of stuff going on. Reasonably dry finish with a bit of hop bitterness. Pretty much nothing like what I imagine an Oktoberfest to be, but I'm expecting it'll be reasonably drinkable. This batch had a complex history--the temp got dropped too low immediately after pitching; repitched another Kolsch tube three days later, then fermented steadily at 65F for a week, followed by about 63F for ~20 days, cold crashed for 3. There was still a big frothy krausen on top when I popped the lid off but I'd hit gravity so decided to go ahead and bottle. Need to get this one through the pipeline, especially since I've got so much coming behind it.
