Microbial Control

Lysozyme is a naturally occurring enzyme isolated from egg whites. It is used in wine to inhibit lactic acid bacteria. Lysozyme degrades the cell wall of gram-positive bacteria such as Oenococcus, Pediococcus, and Lactobacillus. Due to their protective external membranes, Lysozyme is not effective against gram-negative bacteria like Acetobacter. It also has no activity against yeast. Lysozyme’s effectiveness depends not only on the type of bacteria, but also the number of cells present. Unlike SO2, Lysozyme is more effective at higher pH’s when lactic acid bacteria growth is favored. Lysozyme does not replace SO2 because it has no anti-oxidative effect. It can, however, be used to help greatly reduce the amount of SO2 needed to achieve microbial stability over the life of both red and white wines.

Brettanomyces Control with Chitosan, No Brett Inside is an effective tool to control Brettanomyces in the cellar. Comprised of chitosan, a natural polysaccharide from Aspergillus niger (same organism where oenological enzymes are sourced), No Brett Inside has been shown to reduce Brettanomyces populations to 0 after 10 days of treatment.

No Brett Inside has been administratively approved for continual use under 27 CFR 24.250. As a result of updated TTB regulations, customers using No Brett Inside do not have to file an application for use.

The tablet OENOSTERYL EFFERVESCENT slow releases 2g of SO2 when added directly into the wine or must, thus producing an effervescence which helps to achieve good mixture. For use on volumes
superior to 400 L we recommend a homogenization to insure an effective distribution of the sulfitage. Unstable product: when used in contact with air, the SO2 contents and effervescence decrease. To be
stored in an air tight container. Optimal date of use: 24 months after packing date. Box contains a quantity of 48 2 g tablets or 96 g per box.

The tablet OENOSTERYL EFFERVESCENT slow releases 5g of SO2 when added directly into the wine or must, thus producing an effervescence which helps to achieve good mixture. For use on volumes

stored in an air tight container. Optimal date of use: 24 months after packing date. Box contains a quantity of 48 5 g tablets or 240 g per box.

Potassium metabisulfite (KMBS) is a white crystalline salt, which contains 57.6 % sulfur dioxide (SO2). Potassium metabisulfite is dissolved in warm water before being used. It reacts with natural acids to release sulfur dioxide, which protects from unwanted microorganisms and oxidation. A great antioxidant and antimicrobial agent. Can be added directly into solution, sprayed on the top layer to prevent yeast film, and can be used as a general sanitizer.
