The time between grape harvest and yeast addition is a major risk for the development of microbial spoilages (non-saccharomyces yeasts, such as Brettanomyces, that often result in faults, as well as bacteria, etc.). Instead of destroying these microorganisms with sulfites, bioprotection helps to control the ecological niche with a known selected yeast.
Lamothe-Abiet has selected Excellence® B-Nature® through extensive research. This Metschnikowia pulcherrima strain has particular characteristics that make it suitable for bioprotection:
- Control to natural flora when harvesting
- Reduce the amount of compounds that combine SO2
- Increase the wine’s aromatic complexity
- Decrease the dosage of SO2 on the grapes
This product is allowed for a use in Organic and NOP according to the current regulations. See the certificate.
