Chitosan Origin

The Chitosan presents in NO BRETT INSIDE™ is 100% fungal origin from Aspergillus niger and in compliance with OIV International Oenological codex.
It is guaranteed through 4 different characteristics:
-Three characteristics established by Resolution OIV/OENO 368/2009:
-a content of residual glucan > at 2 %,
-a settled density ≥ at 0.7 g/cm³
-a viscosity in solution 1 % in acetic acid 1 % < at 15 cPs
-One characteristic established by Res OIV-OENO 728-2025
Isotopic ratios ¹³C/¹²C and ¹⁵N/¹⁴N: δ¹³C > −14.2‰ or δ¹³C < −24.9‰ but if −25.1‰ ≤ δ¹³C ≤ −24.9‰, then δ¹⁵N > +2.7‰.

These characteristics guarantee the authenticity of fungal chitosan from Aspergillus niger and exclude any animal origin, that is not admitted by the OIV.
As part of our commitment to quality, transparency, traceability and responsibility towards our customers and wine consumers, we can provide—upon request— a product certificate with the four characteristics listed above, confirming the fungal origin (Aspergillus niger) of the chitosan used in NO BRETT INSIDE™.
