Formic acid

This acid (also methanoic acid, formylic acid) is a colourless, caustic and water-soluble liquid. In nature, it is often used by plants and animals, such as the eponymous ants (lat. formica) or wasps and nettles for defence. When drinking alcoholic beverages (wine, distillates), any methanol present in the body is converted to toxic formaldehyde and this is converted to formic acid. Formic acid is ten times stronger than acetic acid and can only be broken down very slowly, which leads to dangerous acidity of the blood. See all wine ingredients under total extract.
