TANETHYL^® Effe

Tanethyl Effe is a combination of ellagic and proanthocyanidinic tannins extracted from grape seeds by means of a patented system that locks an active acetaldehyde molecule (ethanal bridge) to the tannin. Tanethyl Effe is best utilised during the early fermentation stages as the absence of ethanol means that there is minimal acetaldehyde available for interacting with the colour compounds, meaning they are more susceptible to loss through oxidation. In rosé wines, the scarce quantity of anthocyanins and the considerable SO2 content often cause an increase in yellow hues and a decrease in the typical aromas of these wines. The addition of Tanethyl Effe grants stability and longevity of both pink-violet colours and floral aromas.
