PART II

3. Wines

TITLE: USE OF SELECTIVE PLANT FIBRES IN WINE

Definition:

Use in wines of a selective adsorbent composed of plant fibres.

Objectives:

1. To reduce the ochratoxin A levels in wines;
2. to reduce the number and levels of phytosanitary product residues in wines.

Prescriptions:

1. Selective plant fibres are to be used as processing aids and incorporated either into wine or during filtration with continuous deposition, during cross-flow filtration, or as a constituent of a filter sheet;
2. the recommended dosage is to be determined according to the filtration technique used, without exceeding 1.5 kg/m2 of the filter sheet surface area or 200 g/hL in wine;
3. selective plant fibres used in wines are to be removed by racking after sedimentation, centrifugation, or filtration;
4. selective plant fibres are to be used in wines in compliance with the regulatory requirements, particularly the permitted limits for phytosanitary product residues;
5. selective plant fibres should comply with the prescriptions of the International Oenological Codex.

Recommendation of the OIV:

Admitted.
