Improve Yields, Color, Clarification & More
Enological enzymes have proven their value in wineries around the world to produce wine with enhanced varietal aroma, flavor, mouthfeel, and color. Selective release of these flavor, color, and aromatic compounds from the epidermic and hypodermic cell layers of the grape skin serves to increase varietal intensity without introducing undesirable components. The right blend of enzymes can be used to enhance and support the winemaking process to achieve desired and reliable results. These enzyme activities are offered by Gusmer as IFF liquid enzymes and BioSelect micro- granulate enzymes.

Customer Testimonial
