Aromatan is a mix of tannins derived from grapes and gall, studied to preserve the aromatic intensity of white wines. White wines are endowed with less tannins than red wines and are therefore more easily subject to oxidations. Aromatan revives the taste of white wines, making them look younger and mitigating tired or too evolved sensations, as it partially reintegrates the native proanthocyanidinic tannins extracted from grapes.
