EXTRATAN VINACCIOLO is an enological tannin extracted from grape seeds, recommended for the treatment of white, rosé and red wines. Thanks to its origin, it contributes tannins similar to those naturally present in fully ripe grapes, enhancing the wine’s structure and overall balance.
The product is obtained from the seeds of white grapes, separated from the skins before the distillation process and processed through a rapid and controlled production cycle that ensures consistent quality of the raw material.
ExtraTan Vinacciolo is a condensed tannin (proanthocyanidin) of the same nature as the tannins naturally found in grapes. During extraction, only the medium- and high-molecular-weight fractions are selected, contributing to wine structure and stability without imparting vegetal, green or unripe notes.
In addition to its structural contribution, ExtraTan Vinacciolo interacts with proteins and coloring compounds, helping to limit oxidative phenomena and stabilize the wine’s color. Its antioxidant activity can, in many cases, reduce the amount of sulfur dioxide required for wine protection and preservation.
