Product Information.
Anthocyanins Extraction on Grapes

Anthocyanins are chemical compounds present in the peel of grapes, whose color changes depending on the acidity of the surrounding environment. They are part of the polyphenol group. In addition to significantly influencing color (depending on the variety of grapes), they protect the grapes from sun radiation. Anthocyanins are scarcely soluble in must and water, but very soluble in the alcohol produced during fermentation. The color of the future wine depends therefore on the degree of maturation of the species of wine and the duration of the peel-juice maceration.

In addition, the concentration of polyphenols strongly influences the stability of a red wine during ageing. Therefore, in the case of a red wine, it is important to take into account the phenolic maturity of the grapes when choosing the harvest period.
