Grape tannins
It is a natural additive that is essentially extracted from the skin and seeds of white grapes. Grape tannins belong to the polyphenol family and have a recognised antioxidant power. Within the food industry, they are used in oenology as a supplement that improves the quality of wine, stabilizing its colour and optimizing its structure.In Vinumar, we offer tannins from selected white grapes in powder form.
