    Hi guys.

    I went for a more "American wild" style wort in a batch from December, three carboys full, with different yeast/bacteria blends in each. The wort was 75% pils, 25% wheat. This was my first time using Floor malted Boho pils. I did not do a long boil, in fact I think I cut it short at 45 min because I hit my volume.

    Today I did some smelling and tasting, and there is some ridiculous levels of DSM in all three. this is the first time I have ever had DSM issues in a brew, so I'm a little bedside myself. The cause is obvious, slow cool fermentation, short boil and a shit tons of Pils malt.

    So... is there anything I can do? will time clean it out? will the bacteria help? do I need to dump out 15 gallons of wort?

    Thanks guys.

    First, it is DMS :). With a lambic it will be gone so long before the beer is ready to drink, no worries.

    Don't be so hard on him; he probably did too much LDS in the '60s.

    My understanding is that during fermentation DMS may be lightly reduced by CO2 scrubbing, but fermentation itself can only increase DMS levels, by reducing DMSO (some yeast does this on a low level, but some wild yeast / bacteria can produce more prodigious amounts under the wrong conditions).
