Caftaric acid is a hydroxycinnamic acid. Caftaric acid is a natural product found in Vitis rotundifolia, Vitis cinerea var. helleri, and other organisms with data available. Caftaric acid is a metabolite found in or produced by Saccharomyces cerevisiae. Caftaric acid is a non-flavanoid that impacts the color of white wine. Many believe this molecule is responsible for the yellowish-gold color seen in some whites wines[citation needed]. Aside from wine, it is abundantly present in raisins. Caftaric acid is a natural compound. Caftaric acid is a natural compound.

Cis-Caffeoyl tartaric acid

Cis-caftaric acid, also known as (2s,3r)-cis-caffeoyl tartaric acid or cis-caftarate, belongs to coumaric acids and derivatives class of compounds. Those are aromatic compounds containing Aromatic compounds containing a cinnamic acid moiety (or a derivative thereof) hydroxylated at the C2 (ortho-), C3 (meta-), or C4 (para-) carbon atom of the benzene ring. Cis-caftaric acid is practically insoluble (in water) and a moderately acidic compound (based on its pKa). Cis-caftaric acid can be found in common grape, which makes cis-caftaric acid a potential biomarker for the consumption of this food product.
