OenoRed^® is used to soften red wines and increase color stability. It is a natural yeast derivative and contains a high proportion of complex cell wall polysaccharides, due to a special refining process. These polysaccharides mainly consist of mannose and glucose, being able to stabilize anthocyanins and tannins released from the grape skin. Especially the polyphenol‐reactive mannoprotein can bind astringent tannins. The results are red wines with increased refinement.

The wines show higher colour intensity, rounder finish and better integration of inharmonious tannins. OenoRed^® is best used with must or during the mashing process to promote early protection and complexation. When used at the end of alcoholic fermentation, especially the binding of the hard tannins is effective, the wines appear softer and rounder on the palate.

In addition, OenoRed^® is a fermentation nutrient obtained from natural and pure yeast. It can be used to complete yeast nutrition with DAP and other nutrients. This leads to a further significant improvement in wine quality.
