Lacto from grain

    I'm shooting from the hip here. I've read a little and listened a bit... Let's grow some lactobacillus! 15g of DME into 200ml of water for a slightly weaker than usual starter wort. Boiled it. "Cooling" it down to around 100F. Gonna drop it a bit of uncrushed grain and hope for the best.

    This just looks like a bad idea, but some people are getting good results. We shall see.

    as long as the grain is fresh and relatively free of contaminants you should be able to get a good culture off the grain.

    i've had great luck getting a clean lacto ( :-/ ) culture from letting unboiled wort ferment. it was tasty.

    Mashing temps do a nice job of.killing almost everything and sparing the lacto.

    Cool, thanks guys. I'll let this one roll and if it goes south I'll try a mash.

    The easy way it to just set aside a few cups when you're already brewing.
    Or you could try doing what you did but adding the grain at ~150f.

    Nothing so far besides a vague, almost acetic smell. I'm dumping it. I might check it with a ph strip before it toss it.
