Caftaric acid is an ester formed from caffeic and tartaric acids. It is found in grape skins, pulp, and stems. It is not present in seeds. Caffeic acid is a free cinnamic acid. Both the ester and free cinnamate are found in wine. Other cinnamate esters in grapes include fertaric and coutaric acids. The relative proportions of the different cinnamic acid esters varies by variety. 
Caftaric acid is readily oxidized during processing and fermentation. In the presence of polyphenol oxidase enzyme, caftaric acid forms a highly reactive quinone that can oxidize other compounds in coupled oxidations. The quinine can also combine with other compounds to form adducts. Glutathione and caftaric acid react to form a compound known as grape reaction product.
