Molecular SO2 effect on Brettanomyces bruxellensis populations during a one-year storage

This work confirms that B. bruxellensis development can be tempered by SO2 addition if a sufficient molecular concentration of 0.8 mg.L-1 is achieved. However differences do exist among strains in terms of cellular multiplication and cultivability. This in turn has an impact on VP production.
