The release of mannoproteins during yeast autolysis requires a complete degradation of the yeast cell wall. Certain winemaking techniques such as sur lie ageing and the use of glucanase enzymes allow this process to occur over time.
However, mannoproteins can also be prepared from isolated cell wall fractions. These blends of products have the benefit of quickly integrating into wine.
Additives containing readily available mannoproteins can be used during fermentation to improve wine colloidal stability. The interaction between yeast polysaccharides and tannins can
significantly impact the perception of tannin astringency, creating a fuller structure and better integration on the palate.

For optimal performance during fermentation, the range of yeast derivatives contained in the Enartis Pro Range can provide a source of readily available mannoproteins. These polysaccharides are also capable of interacting with color and aroma compounds, enhancing the persistence of flavors.
EnartisPro R is a fermentation aid derived from inactivated yeast with a high content of soluble mannoproteins. Its formulation was designed to immediately stabilize must components.
Benefits from using EnartisPro R include:
EnartisPro Blanco is a fermentation adjuvant obtained by thermal inactivation of a yeast strain containing sulfur amino acids with antioxidant properties. The thermal inactivation process results in a high content of free mannoproteins which can immediately stabilize compounds present in must.
Benefits of using EnartisPro Blanco are:
EnartisPro Tinto is a fermentation adjuvant derived from Inactivated yeast with high content of soluble mannoproteins in combination with a mixture of condensed grape seed tannin and ellagitannins extracted from chestnut wood. This formulation was designed specifically to protect color and favor anthocyanin/tannin condensation during the maceration of red grapes.
Benefits from using EnartisPro Tinto during fermentation of red grapes:
