In order to release terpenic substances and bouquet precursors, which normally remain for the most part trapped in the pomace, AEB studied and worked out enzymes with a high extraction and complementary β-glucosidasic activity. With its high secondary cellulasic activity, Endozym Cultivar enables to improve the passage of aromatic precursors from the grape cells to the must; such compounds are released by the sugars, to which they are linked because of the secondary β-glucosidasic activity.
