Lallemand Specific Inactive Yeast


Natural yeast derivative for the production of premium red wines

Opti-Red is a distinctive natural inactivated yeast product specifically designed to enhance roundness and color stability in premium reds. Due to a specific refining process, Opti-Red contains a high level of polyphenol reactive cell wall polysaccharides which can react with tannins and anthocyanins as soon as they are released from the grape skins. This results in red wines with more intense color, rounder finish and better tannin integration. Opti-Red can be added to the must to encourage earlier complexing or to the latter part of the alcoholic fermentation to help shape harsh polyphenols into smoother more approachable tannins. Opti-Red is a natural yeast derived nutrient that can supply certain fermentative advantages together with significant wine quality improvement.
