Rapidase GlucanFree
Enzyme for the Botrytis β-glucans degradation in juice and wine
PURPOSE
Rapidase® GlucanFree facilitates juice and wine clarification and speeds up filtration in the presence of glucans from Botrytis cinerea.
Composition
This liquid enzyme preparation contains β-glucanases able to hydrolyze β-glucans, thereby improving clarification and filtration speed, and safeguarding wine quality.
Speeding up the filtration step and decreasing filter clogging, Rapidase GlucanFree enables also to reduce the Eco or Carbon footprint of the winemaking process thanks to water and energy savings.
Naturally, it contains negligible levels of cinnamyl esterase (nFCE) in order to preserve aroma freshness whichever your yeast choice might be.
Tested and Validated
To offer the best efficiency in application, each Rapidase® formulation is developed and tested with the world’s most renowned wine research institutes and validated in wineries at production scale.
Our technical and sales staff is available to provide you with test results as well as assist you in evaluating the products premium performances in your specific conditions.
