Ideal Uses: Botrysized or moldy grape musts.Oxidative protection.
The main philosophy of the Microcel product is that modern winemaking usually prefers a preventive approach instead of a curative one.
Using Microcel winemakers stops oxidation at its onset.
Microcel is an active-absorbent clarifier for musts and wines.It is composed of potassium caseinate, active fibers, and micronized pharmaceutical bentonite.
During fermentation, Microcel absorbs the proanthocyanidins and monomeric catechins, which cause oxidation in wines.
The color of treated wines becomes more appealing with greenish hues in white wines or more defined pink hues in the case of rose’ wines.
Musts treated with Microcel produce more complex wines, which retain their individual characteristics longer.
Effects of different Microcel components
Using potassium caseinate during fermentation results in a lower level of oxidable polyphenols (procyanidins and catechins), lower dissolved oxygen (DO) and therefore a finished wine that is going to be more resistant to oxygen. Potassium caseinate also fines for copper as well as iron (up to 50% of the initial content).
The Bentonite used in Microcel is an extremely fine earth product selected to be very high in Na+. Having bentonite in the fermenting must is going to result in several advantages:
Reduces the amount of bentonite required for protein stabilization
Absorbs laccases and triosynases which oxidize polyphenols
Activated Celluloses improve fermentation kinetics by absorbing toxins and long chain fatty acids that inhibit the yeast during fermentation.
Also, the cellulose is going to work as a “boat” for the yeast cells so they can stay well suspended in the media.
This is crucial especially in cold fermentation, when the activity is quite slow and there is little CO2.
In these conditions yeast usually tend to precipitate down and bacteria take over in the upper part of the tank causing VA production.
Dosage Rate & Usage Instructions
Dissolve the dose of Microcel in about 5-10 parts of cold water, wait approx 15 minutes, add to mass quickly and with mixing.
