PHYLIA® EXEL results from the association of mannoproteins and other proteins from a specific yeast strain. The mannoprotein content of PHYLIA® EXEL allows tartrate stability for white, rosés and red wines with medium-low instability (testing recommended to determine the addition rates). PHYLIA® EXEL interacts strongly with the wine composition by decreasing the harshness and astringency of tannins in red wines as well as the sensation of acidity in white and rosé wines. The wines are silkier, their texture rounder, the aromas more complex (effect of mannoproteins). PHYLIA® EXEL efficiently refines wines just before bottling.
