OPTI-MUM Red

OPTI-MUM RED™ is a new innovative product from Lallemand. It is a specific yeast autolysate, from a specific wine yeast that has undergone a unique Lallemand process called Mannoprotein Extraction Treatment (MEX), thereby enabling a quick release of the components of interest. Adding OPTI-MUM RED™ at the beginning of alcoholic fermentation maximises the formation of complex polyphenol-polysaccharide chains. The formation of these stable, soluble complexes between polyphenols and yeast mannoproteins has recently been established (Mekoue et al. 2016). The early formation of these complex polysaccharide-polyphenol chains results in wines that are more intense in colour, have a more rounded mouthfeel and a decreased perception of astringency.
