Polyclar Wine is a stabilizer composed by PVPP in granules, ideal for correcting and preventing the oxidation effects on phenolic substances. Its characteristics are due to the high ability to adsorb the flavanic polyphenols, the main substratum of maderization and browning phenomena of white and rosé wines. The contact with oxygen may lead to alterations of color and smell, which brings an oxidized tone and taste, which becomes bitter.
