Rapidase® Glucalees 100g pack

The use of Rapidase® Glucalees speeds up natural yeast autolysis and in the case of Botrytis affected grapes, enhances filtration.
Rapidase® Glucalees is an enzymatic formulation derived from cultures of selected strains of Aspergillus niger and Trichoderma harzianum. In addition to its pectolytic activities this specific formulation contains essential ß-glucanase activivity targeted for optimal glucan degradation both in filtration of wines from Botrytis infected grapes and ageing on lees. Rapidase® Glucalees contains pectinases and ß-glucanase for improved viscosity reduction of must and wines. Rapidase® Glucalees contains ß-glucanase for accelerated yeast cell walls lysis resulting in the release of polysaccharides, principally mannoproteins. Rapidase® Glucalees allows in a few weeks (6 to 8 weeks) to achieve results that equate 6 months traditional ageing on lees. Rapidase® Glucalees naturally contains a negligible level of cinnamyl esterase to preserve the crisp and fruity character of wines even when a POF (+) yeast strain is used.

Oenological characteristics
• Improves filtration and clarification of wines from grapes affected by Botrytis cinerea.
• Allows for improved filter yields and lower wine losses.
• Allows for reduced use of filter aids.
• Optimises the release of yeast polysaccharides such as mannoproteins.
• Allows for shorter ageing time.
• Allows for enhanced mouthfeel.
