      "Remove all methanol" is sound advice. However I doubt that
      methanol is the problem here. I'd be looking at other things
      like 'nasties' produced by stressed yeast working under less-than-
      ideal conditions, like too little nutrient, poor temperature
      control, O.G too high, any one of a dozen things that affect the by-
      products that yeasts make. Some of these do carry over.

      The amount of methanol produced by pure sugar fermentations is
      negligable. All grain fermentations produce a heck of a lot more,
      and in fact methanol is present in even the very best commercial
      Scotch Malts, ranging from 38 to 140 ppm (parts per million).
      Moonshine tested at the same time on the same gas chromatograph
      showed methanol at 41 ppm.

      The amount of methanol needed in your system to produce signs of
      poisoning is very high (15 - 30 ml of 40% solution).

      Speaking of 'signs of poisoning',...
      (source: http://www.homestead.com/emguidemaps/files/methanol.html )

      - many of the early symptoms of methanol poisoning are non-specific
      eg. headache, dizziness, malaise, generalized weakness, altered
      sensorium, acute mania, and paresthesias.

      - the most characteristic symptoms that are very suggestive of
      methanol toxicity are the visual symptoms - blurred vision,
      decreased vision, snowfield blindness - described as "seeing a
      snowstorm" or "stepping into a snowfield", visual scintillations,
      photophobia, constricted vision or visual field defects, total
