Enzymes are organic catalysts of a proteic nature whose job is to accelerate (catalyse) chemical reactions that bring about the formation or breakage of chemical bounds. Ont of the most important properties of enzymes is their capacity to react in a highly selective manner with one substance (substrate) or on a group of similar substances. This allow them to act in a targeted manner, chosen according to necessity, for the most ideal commercial application.


Pectins are among the most prevalent colloids in both must and wine. These substances have an elevated solvation capacity and thus increase the solubility of other substances including salts (sodium bitartrate), proteins, etc. Thus, pectins impede both stabilization and clarification. Moreover, pectins tend to gelatinize relatively easily ans are therefore an impediment towards filtration.


The enzymatic preparations from Enologica Vason all have an elevated pectolytic activity that provides, depending on the product, a series of secondary enzymatic activities, including proteolytic, cellulolytic, hemicellulolytic, glycolytic, etc.

These enzymes are always obtained by production processes that guarantee the final product to be virtually free of undesirable secondary activities (polyphenoloxidases, cinnamylesterase, anthocyanase, pectin-methyltransferase) and do not require any additional purification steps.


enzyme extration procedure - Fractioning

Using the same quantity of Zimared® Plus and dividing the dose into three, ensures the presence of the enzyme (and therefore the color extraction) throughout the process.

enzyme extration procedure - Localisation

It is useless to distribute Zimared® Plus over the whole pressed mass.
By concentrating the dose on the cap, and therefore on the skins, the enzyme has time to act.

enzyme extration procedure - Differentiation

Two specific enzymes in two different phases: Zimared® Plus fractionned over the maceration, and Extrared L on the first day of racking.
This makes a differentiated enzyme action possible.
