Winemaking tools


A controlled production process for wine bacteria to offer the most efficient performance and high quality wines

Our wine bacteria benefit from the highest quality production skills and facilities!

As a specialist producer of lactic acid bacteria since 1988, Lallemand has 9 bacteria production facilities worldwide. We  grow bacteria for a very wide variety of applications, including for winemaking. We even have a dedicated wine bacteria production plant and team based in St-Simon,  France.

After 30 years of continuous improvement and  investment, we haves the  expertise  to supply over 35  active freeze-dried wine bacteria to use in wine. Each one has its own growth procedure, guaranteeing its malolactic-fermentation performance after inoculation in wine.

Our  7 different stages of the production process are subjected to very strict quality controls. The production plant holds FSSC 22000, ISO 9001, and GMP certifications.

We  guarantee that our wine bacteria are traceable and OIV compliant, perform well for malolactic fermentation, and are easy-to-store (3-year shelf life).   All this to optimize  your wine potential.

Acclimatisation of MBR Bacteria for the induction of MLF in difficult or harsh wine conditions

Although MBR bacteria are designed to withstand direct inoculation into wine, if the wine conditions are particularly hostile, Lallemand recommend to ‘acclimatize the bacteria to the particular wine conditions. The following document outlines the procedure to acclimatize MBR bacteria in harsh conditions.
