I am struggling to get the final gravity of my lager down. I'm brewing a pilsner (but throwing in some extra hops).
I have tried re-hydrating the yeast (using two packets for an 18 litre batch) using sterile water at about 23 degrees, then have tried pitching into pre-cooled wort and also tried wort at about the same temperature in case I am shocking the yeast.
Fermenting at a constant 12 degrees (have also tried at 14) using a brewPi. Diacetyl rest does not affect the FG
I'm giving it plenty of O2 from a cylinder and air stone - seems to make no difference.
I've done four or five batches now and nothing gets below 1.020 . Completely stumped I have a few more packets of s23 to use up but I'm thinking of ditching it and switching to W-34/70
Crappy batch of s23 ? Anyone else had similar problems ?
