Opti Malo Plus

Please select from the following option(s) to see pricing and availability.

Opti'Malo Plus is a natural nutrient developed by Lallemand specifically for Malolactic Fermentation. It is a blend of inactive yeasts rich in amino acids, mineral cofactors, vitamins, cell wall polysaccharides and cellulose. The cellulose provides surface area to keep the bacteria in suspension and to help adsorb toxic compounds that may be present at the end of primary fementation.

Opti'Malo Plus serves an analogous function to Fermaid-K for yeast fermentations.

To Use:
Suspend in a small amount of wine or water (just enough to dissolve it) and add to the wine at the same time as the Malolactic bacteria. Opti'Malo Plus should not be added directly to the rehydration water.

Recommended Dosage: Use Opti'Malo Plus at a rate of 1 g/gal of wine.

A rough approximate of weight is 1 tsp = 3.1 grams. We highly recommend using a scale to weigh the product for an accurate dose. We do not recommend relying on these rough conversions for accurate dosage rates.

What is the shelf life of Opti Malo Plus?
Brock McDaniel on Oct 29, 2018
BEST ANSWER: I think MoreWine says 6 months.
However, I vacuum pack all of my opened wine additives, and have used them for years without problem by doing that. What damages these products is moisture and oxygen. Vacuum packing eliminates both.

Works really well
I always have good luck with my malo-lactic fermentations using this product before inoculating with Viniflora CH16. I have vigorous reactions and complete ML ferment usually within 3 weeks.
