Galacturonic acid

One of the acids contained in wine in small quantities, which is one of the non-volatile acids. The complete name is D-galacturonic acid, the chemical name 6-carboxy-D-galactose. It is formed during fermentation from the pectins (cell substances of combs and berry skins) and occurs particularly in noble sweet white wines (hence also botrytis acid). The acid is an oxidized form of D-galactose (mucilaginous sugar) and is one of the dietary fibres (indigestible food components). Through oxidation of the galacturonic acid the mucic acid (galactaric acid) is formed. See a list of all wine ingredients under total extract.
