Phenol components significantly enhance the antioxidant properties, color and mouthfeel of red wines. The importance of these phenol components in sensory perception requires assay at all stages of the winemaking process.

Any polyphenols in the sample react with Folin-Ciocalteu’s reagent in basic medium. The color increase is directly proportional to the polyphenols concentration of the sample.
