Water: "bring to a boil and hold for 5 minutes" -- I usually get my water ready to boil the night before, so this step would be simple enough. Can this step be done a few hours earlier than the brew, or would oxygen sneak back in during the dead of night?
Mash: "drain wort into kettle" -- sometimes I mash the night before, drain into the brew kettle, put the lid on and then turn the BK on as soon as I wake up. Would holding the wort overnight reintroduce oxygen?
SMB -- sodium metabisulfite -- to be clear, this is what's in Campden tablets, right?
I'm not the expert, but I don't think either of those practices is compatible with low oxygen brewing.
I believe some Campden tablets are SMB and some are potassium MB. According to the original lodo paper, one campden tablet contains 440 mg of SMB.
Thanks. I think I must know a chemist or two to answer the first question.
