And we still poison alcohol to make it undrinkable: > Denatured alcohol (also called methylated spirits, in Australia, Canada, Ireland, New Zealand, South Africa, and the United Kingdom; wood spirit; and denatured rectified spirit) is ethanol that has additives to make it poisonous, bad-tasting, foul-smelling, or nauseating to discourage its recreational consumption. It is sometimes dyed so that it can be identified visually. Pyridine and methanol, each and together, make denatured alcohol poisonous; and denatonium makes it bitter. https://en.wikipedia.org/wiki/Denatured_alcohol https://en.wikipedia.org/wiki/Denatured_alcohol
