AEB Primaflora Vb Bio – 500g

PRIMAFLORA VB BIO is a complex biological formulation for the microbiological protection of white and rosé musts. It contains non-Saccharomyces yeast strains, Metschnikowia pulcherrima (selected in collaboration with the University Institute of Vine and Wine (IUVV), University of Burgundy. These species, naturally present on the grapes, contribute to the gustative and aromatic complexity of wines. PRIMAFLORA VB BIO was chosen for its ability to quickly establish itself in the environment, thus limiting the development of undesirable flora such as Brettanomyces, apiculate yeasts and lactic acid bacteria, all of which contribute to the production of biogenic amines, H₂S, butyric odors, phenol-volatiles, Acetic acid, etc. Unlike sulfiting, PRIMAFLORA VB BIO limits the combination of SO₂ at the end of fermentation and prevents selection of SO₂ resistant strains. It also enhances the purity of terroir expression by preserving the natural enzymatic systems present and limiting the extraction of unwanted flavors and greenness. PRIMAFLORA VB BIO is used directly on the grapes from the first minutes of the harvest. After decanting or pressing, the addition of a Saccharomyces cerevisiae ADY yeast is necessary to control the alcoholic fermentation.
