      Yep, you nailed it Marc. One won't work without t'other. I
      think 'synergy' is the word we're looking for.

      Riku, I would repitch the yeast as you've already stressed the
      original yeast and its action will be unpredictable. Because its
      stressed it will also be making nasty things, so if you intend to
      save the wash from the drain, make sure you only distil it to recover
      neutral alcohol, not for the flavour.

      You guys are doing the right thing. In all experimentation, only
      change ONE variable at a time & then record the results. Then adjust
      the fermentation with what you consider to be the remedy and record
      that also. It's all trial and error, but it's the only way to figure
      out things successfully. Good work.

      regards Harry
