Unitech Scientific - Model PHE-F150 -Wine Phenolic Kit

Phenolics in wine include tannins, anthocyanins, polymeric pigments and monomeric phenols (e.g. caffeic acid, caftaric acid, catechins, quercetin, kaempherol, and gallic acid) and are responsible for wine color, bitterness, and astringency.  Color and flavor profiles of finished wine are affected by grape selection and winemaking techniques. Total phenol content, as well as color and hue data, can provide valuable information for optimizing these processes.
