Relationship between lactic acid bacteria, malolactic fermentation and wine colour

Some phenolic acids can either inhibit or stimulate the growth of Oenococcus oeni and other lactic acid bacteria (LAB) in wine. It has been observed that some LAB metabolism could have an influence on wine colour. In this article, some of the relationships between LAB, malolactic fermentation (MLF) and phenolic compounds are summarised; these relationships are important for the selection of LAB to make starter cultures and are of interest for wineries in terms of its effect on wine colour
