Prevent Volatile Acidity in Fermentation
Cellarscience Killazyme is a lysozyme that is used to control and inhibit gram-positive lactic acid producing bacteria including Oenoccoccus, Pediococcus, and Lactobacillus. This is a tool winemakers can use throughout the winemaking process to limit bacteria contamination and the production of volatile acidity. Killazyme does not affect gram-negative Acetic Acid bacteria nor yeast.
Use Killazyme to Prevent Volatile Acidity
Killazyme can be added at the start of fermentation to limit lactic acid bacteria before it happens. Under certain situations lactic acid can use sugar or citric acid which it converts into acetic acid and volatile acidity. Killazyme is effectively used at the start of fermentation when you know or suspect a slow to start fermentation.
Use Killazyme at First Signs of Problem Finish
Killazyme can also be added at the first signs of a problematic ferment to help limit the production of volatile acidity. This reactive addition requires a heavier dosage than a preemptive addition as there is most likely volatile acidity already present.
Use Killazyme to Avoid MLF in White Wines
When fresh, crisp white wines are desired, Killazyme can be added at the start of a white wine fermentation, or at any point in tank or barrel, to block lactic acid activity and prevent MLF. We still always recommend a sterile filtration for commercial whites before bottling to prevent a later MLF in the bottle.
Barrel Storage Protection of Reds
After MLF is complete and you storing wines in barrel, Killazyme is a great insurance policy to reduce the risk of volatile acidity.
