EXTRATAN RED is an ellagic tannin obtained from chestnut wood (Castanea sativa) that has been naturally seasoned outdoors and extracted through an exclusive hydroalcoholic process. Thanks to its composition, it is recommended for the protection and stabilization of red wines from the earliest stages of vinification.
When used during maceration, ExtraTan Red promotes color stabilization by encouraging the combination of anthocyanins and tannins, contributing to the formation of stable colored complexes. This helps produce wines with greater color intensity and enhanced aging potential.
In addition to its role in color stabilization, the product provides significant antioxidant protection, helping to safeguard the wine against oxidative phenomena that may negatively affect its aroma, color and freshness.
ExtraTan Red also contributes to reducing the reductive character of wines by promoting the formation of bonds between tannins and thiol compounds, thereby limiting the accumulation of substances responsible for undesirable reductive odors.
Thanks to its chelating properties toward iron and copper, the product helps prevent ferric and cupric hazes, contributing to the long-term stability and quality of the wine.
