Tanéthyl is a pure proanthocyanidin sourced from ripe grape seeds and associated with an ethanol bridge for fast color stabilization and flavanolethy-flavanol polymerization. The utilization of Tanéthyl is highly recommended for stabilizing color after fermentation in absence of oxygen and ellagic tannins. In rosé wines it stabilizes the color without the need of MOX, which is never recommended for these types of wines.
