Acti-ML is a Malolactic nutrient used during rehydration of both direct inoculation and standard-type Malolactic Bacteria strains. It is a specific blend of inactive yeasts rich in amino acids, mineral cofactors and vitamins. These inactive yeasts are mixed with cellulose to provide more surface area to help keep the bacteria in suspension. Acti-ML can help strengthen the development of bacteria growth under difficult conditions.

Please note that due to its unique formulation, only Acti-ML can be used in the hydration phase of malolactic bacteria. Other ML nutrient formulas are not compatible with this protocol and their use during the hydration phase could severely limit the bacteria's viability!

Acti-ML serves an analogous function to Go-Ferm Protect in yeast fermentations.

To Use:
Mix Acti-ML into 5 times its weight in 25C (77F) chlorine-free water. Add your bacterial culture, then wait 15 minutes before adding to the wine. Dosage rate: 0.84g/gal of wine

Should I use this even with a liquid Malo like Wyeast 4007? The website's red winemaking guide is not very clear on this point. It would seem like the Wyeast is already hydrated since it's a liquid, so maybe I don't need this?
Paul R Nash on Oct 25, 2018
BEST ANSWER: I use the Chr Hansen dry CH35 ML after the temp drops below 70 degrees F and the Brix are 2/3 to 3/4 down. I just ad the OPTI'MALO Plus (I do not mix with H2O) at the same time as the ML and then stir off and on for twenty minutes. I add the the OPTI just to help provide an optimum environment for the ML. The package says, "A blend of cellulose nutrients and yeast hulls ... feeds, removes toxins, and keeps the ML in suspension." I use it because it is not very expensive and is easy to use and if it helps to make the wine better, then that is great.

BEST ANSWER: ACTI-ML isn't the nutrient designed to be added to the wine ... it's used during the initial hydration of the ML bacteria. The nutrient to add to the wine during ML is Opti Malo Plus.
