Bioprotection is a natural way to inhibit microbial contaminants (yeast, mold and bacteria). This bio-control not only helps you to prevent flavor defects, it also helps you to build and protect your brand.
Bioprotection has made an important step forward with the advent of metagenomics. Only 1% of the microbial population of the must grows on plates. With metagenomics instead, we can extract and sequence the DNA of all species present and not just those that can be cultivated on a plate.
It was possible to identifythe most suitable species as a starter of alcoholic fermentation. Among Non-Saccharomyces yeast there are harmful strains, but also positive, using only the positive ones is possible to achieve a more complex wine, and at the same time limit the development of unwanted yeasts through competitive exclusion.
The seminars reproduced in these videos were presented at the X edition of Enoforum (Vicenza, Italy, 16-18 May 2017) within the session managed in collaboration with CHR. Hansen:
