SIHA Active Yeast 5 (Agglocompact) is a highly active dry yeast formulated especially for making champagne by fermentation in the bottle or in a fermenting tank. This active dry yeast effects reliable secondary fermentation and compact precipitation of the cells after fermentation in cell clusters (agglomerization). Therefore, it is particularly suitable for making champagne by the “Méthode traditionnelle”. The high agglomerization effect accelerates separation of the yeasts by agitation. Champagne making processes are simplified and production costs are appreciably lowered.
