Abstract

A malolactic ferment is produced from at least one malolactic bacterium strain which is cultured in a culture medium containing an assimilable nitrogen source, malic acid and alcohol. The ferment biomass is separated from the culture medium. The biomass may be concentrated and may be frozen with a cryoprotective agent or dehydrated. The biomass may be added directly to wine to effect malolactic fermentation.
