The research investigated the accumulation of malic acid and diacetyl in the white wines during the alcoholic fermentation of must with a Saccharomyces cerevisiae wine yeasts isolated by the author and Oenococcus oeni malolactic bacteria in a concentration of 106 CFU/mL.

Based on our determinations, it was ascertained that the Oenococcus oeni malolactic bacteria co-inoculation system in fermentative processes leads to a substantial reduction of malolactic bacteria and diacetyl concentrations. Thus, harmonious, balanced white wines are obtained, as specific to the area.
