Gran Tanni Gal

Gran Tanni Gal is a highly pure tannin composed of gallic or digallic acid esters with quinic acid and glucose. This tannin has an average molecular weight of 1600 to 1850 and has been granulated to ensure perfect solubility in water or wine, avoiding waste and inconvenience in use. The main actions of Gran Tanni Gal include:

• Color stabilization: Gran Tanni Gal plays an important role in color stabilization in wines. It forms stable complexes with color pigments present in wines, such as anthocyanins in red wines and flavonols in white wines. These complexes help protect the coloring matter from oxidation and subsequent precipitation, thus helping to keep the color of wine more stable over time.
• Contribution of body and flavor: Gran Tanni Gal can improve the body and flavor of wines that may lack flavor and structure. This tannin can help enrich the sensory profile of wines, adding notes of vanilla and licorice, as well as imparting more smoothness and fullness in the mouth. In addition, it can have a complexing and masking action toward herbaceous and bitter polyphenols, thus helping to balance the taste of the wine.

The use of Gran Tanni Gal as a clarification aid offers the advantage of combining high effectiveness in wine clarification without compromising the structure and characteristics of the must or wine. In this way, more color-stable wines with an enriched sensory profile can be obtained, improving the overall quality of the final product.
