Active dry yeast, especially developed for beer refermentation in bottle or keg (i.e. conditioning), selected for its high fermentation speed, great flocculation and compact sedimentation capability. FERMO R03 has an excellent assimilation of simple sugars but does not metabolize maltotriose, which facilitates the dosage of sugar and the standardization of the refermented beer.
