Common questions
Why is denatonium benzoate added at such low concentrations?+
Because it is one of the bitterest known compounds, only a tiny amount is needed to make the taste intolerable, so manufacturers add just enough to deter drinking without materially affecting the spirit's other properties.
Does denatonium benzoate itself make methanol-adulterated liquor safer?+
No, it only discourages someone from swallowing enough to notice the taste; it does not reduce the toxicity of methanol or other denaturants already present if the liquor is consumed anyway.
