I am finishing a diacetyl rest on a Marzen. In one carboy I made a starter with 2 WLP 830 German Lager yeast that I used a stir plate with. The other I did the same with WLP 833. I gave both two thirty second shots of O2 and shook them for a minute between and after each shot. The results where great. If I pitch my next batch right on top of the yeast cake, what kind of result should I expect? I will of course give the wort another shot of O2.
