Finishing gravity about 1/5 OG which is about right for Nottingham.
Nice one, yeast.

Yep. 1-2mins with O2 as high gravity worts especially need good aeration. Since I started using O2 simply for the sake of speed and ease, and pitching a decent ammount of yeast, every fermentation happens to have gone without a hitch, fairly fast at temps of 17-19c, and with finishing gravities right where I want them.oblivious wrote:Did you aerate the wort?
