This is actually a myth. I’ll have to see if I can find the papers I read but mass spectrometry has shown that methanol comes out throughout the entire process. The idea that things come out at their boiling temperature is a drastic oversimplification. Methanol is really only present in significant amounts in fruit mashes because it comes from fermentation of pectin. Grain or sugar-derived alcohol barely has any at a…
> This is actually a myth. I’ll have to see if I can find the papers I read but mass spectrometry has shown that methanol comes out throughout the entire process. The idea that things come out at their boiling temperature is a drastic oversimplification. Please do find those papers! They may be describing a radical new chemistry that I'm not familiar with. To be clear - methanol boils at 64C and ethanol boils at 78C.…
Temperature is just an average, the individual molecules can have a higher or lower temperature and can therefore evaporate already below boiling point.
