USE OF SELECTIVE PLANT FIBRES IN MUST
THE GENERAL ASSEMBLY,
IN VIEW OF Article 2, paragraph 2 b) ii of the Agreement of 3 April 2001 establishing the International Organisation of Vine and Wine,
CONSIDERING the work of the “Technology” Expert Group,
CONSIDERING Resolution OIV-OENO 582-2017 adopted in 2017 on the use of plant fibres in wines,

PART II
2. Musts
TITLE:USE OF SELECTIVE PLANT FIBRES IN MUST
Definition:
Use in musts of a selective absorbent composed of plant fibres.
Objectives:
- To reduce the ochratoxin A levels in musts;
- to reduce the number and levels of phytosanitary product residues in musts.
Prescriptions:
- Selective plant fibres are to be incorporated into must, or during fermentation;
- the dose to be used is to be determined depending on the must and levels of molecules to be adsorbed, and should not exceed 200 g/hL;
- selective plant fibres are to be removed by racking after sedimentation, by centrifugation or by filtration;
- selective plant fibres are to be used in musts in compliance with the applicable authorisations and limits for phytosanitary product residues
- selective plant fibres should comply with the prescriptions of the International Oenological Codex.
OIV recommendation:
Admitted.
