Co-inoculation strain for rapid MLF without risk of VA

ML PRIME™ is a unique strain of Lactiplantibacillus plantarum that rapidly completes MLF (3-10 days). It lacks the ability to produce volatile acidity from glucose or citric acid, making it safe for co-inoculation.

• Ideal for red wines with ≤ 3 g/L malic acid
• Produces low to no diacetyl and does not produce biogenic amines or precursors for ethylphenol production (by Brettanomyces)
• Shows good resistance to chitosan-based antimicrobial agents (e.g., BACTILESS and ALLIANCE)
• Add ML PRIME to must 24 hours after yeast addition
• Selected by Università Cattolica del Sacro Cuore, Italy

Other Applications:
Must be validated by a benchtop trial, consult Scott Labs for more information

• Can be used for low pH white and rosé wines
• Can be used to restart stuck malolactic fermentations, even when starting malic levels are low

Special Notes:

• Dosage rate: ML PRIME™ is different from Oenococcus oeni. Its cannot multiply in wine and therefore the dose rate must be respected. Avoid blending fermenting wine after inoculation.
• Yeast strain choice: Do not use ML PRIME™ in conjunction with a malic acid-producing yeast strain, such as IONYS_WF
