Caftaric acid is a non-flavanoid phenolic compound. It is found in grape (Vitis vinifera) and impacts the color of white wine. Many believe this molecule is responsible for the yellowish-gold color seen in some whites wines. Aside from wine, it is abundantly present in raisins. It also occurs in Cichorium intybus (common chicory) and is one of the bioactive components of Echinacea purpurea (Eastern purple coneflower).

Caftaric acid and caffeic acid are in a class of chemicals known as cinnamates (hydroxycinnamic acids). Caftaric acid is formed when caffeic acid and tartaric acid undergo esterification. But, during fermentation, caftaric acid is oxidized into its principal components.

Winemakers primarily use Cafteric Acid to measure the oxidation levels that a wine has undergone. Press Wines, which undergo a high degree of oxidation will have little to no Cafteric Acid. This one of the primary methods that winemakers can monitor this harmful process.
