I need a procedure for determination of methanol in alcoholic beverages that can be performed without the need of analytic separation equipment like HPLC or Gas Chromatography. I don't need to quantify the amount of methanol, just determine if it is present.

Hi Martin,
I've found this old method. Don't know if it works:

Boric acid is sufficient for a qualitative detection. Methanol forms a boric acid ester which leads to a green flame during combustion.

Markus
