Endozym Glucapec is an enzymatic preparation formulated for the treatment of wines that are rich in glucans and pectins, derived both from botrytis-affected grapes and from yeast cellular walls. Endozym Glucapec may be utilized on musts or on wines at the end of the fermentation, or during storage. This enzymatic preparation is particularly indicated for the treatment of wines from botrytisaffected grapes, young wines, wines from too ripened grapes or pressed wines. Endozym Glucapec hydrolyzes the protector colloids, facilitating in this way clarification and the subsequent filtration stages, enabling to reduce the dosage of treatment and filter aids.
