I am planning on brewing 3 lagers in September, all with a pale base malt. My eKeggle has a volume of 15.5g and it will be BIAB. I want to knock them all out in one day. One will be a Helles or Pils, one will be a schwarz clone (Koestrizer), and the third I haven't decided yet. Can I just do a high gravity multi-step mash, drain some wort for the base helles, then proceed to do a second/third mash with adding Munich and other malt? Then just boil separately with a water addition to get everything to the right gravity? Am I missing a step or overlooking anything? Any ideas for a third lager style - something with Munich? Could also be an ale, I suppose!
