Endozym Thiol is a liquid pectolitic enzymatic preparation with specific secondary activities, facilitating the hydrolysis of grape thiol aromatic precursors, During alcoholic fermentation, these aromatic compounds are separated through the action of exogenous enzymes and enzymes produced by the yeast. Endozym Thiol is a liquid carbon sulfur lyase that favors the hydrolysis of these aromatic thiols precursors and enhances their expression in the wine.
