A formulation of two strains (Torulaspora delbrueckii and and Metschnikowia pulcherrima) ifor use in harvest bioprotection of grapes and juices, and as an SO2 reduction strategy.
These strains selected from among the grape’s indigenous flora for their organoleptic neutrality will colonize the medium and control the microflora in the pre-fermentation stages.
Combining these two high implantation capacity species, one cryophilic and more SO2 resistant (Torulaspora -in situations where SO2 is added to grapes) and the second ensuring a healthy grape inoculation (Metschnikowia-ensures that the medium is protected by micro-organisms) produces a positive result in a wide range of circumstances.
The bioprotective effects of this preparation have been validated by the results of studies:
Colonization of the medium without any detected fermentation activity (no assimilation of sugars or nitrogen, no difference in turbidity levels at the end of the settling process).
Restriction of the growth of indigenous flora.
Implantation of the inoculated Saccharomyces cerevisiae strain facilitated.
Dosage: 50 ppm of ZYMAFLORE® ÉGIDETDMP directly, rehydrated or non-rehydrated, on grapes or must (healthy grapes). Use a dosage of 100 ppm in case of temperature below 40°F. Next, inoculate with Saccharomyces cerevisiae (at usual dosage) to ensure complete alcoholic fermentation.
