(1) in the table, the following rows 57 and 58 are added: 1 2 3 Oenological practice Conditions of use Limits on use Applications "57 Use of filter plates containing zeolites y-faujasite to adsorb haloanisoles Under the conditions laid down in Appendix 23 58 Treatment with potassium polyaspartate in wine Under the conditions laid down in Appendix 24 No more than 10 g/hl" (2) the following Appendices 23 and 24 are added: "
"
(a) The treatment should be carried out on clarified wines; (b) the filter plates should be cleaned and disinfected before filtration; (c) the application of zeolites Y-faujasite should comply with the prescriptions in the International Oenological Codex.
(a) The optimum dose of potassium polyaspartate used to stabilize wines, also those with a high degree of tartaric instability, must not exceed 10 g/hL. At higher doses, the potassium polyaspartate's (KPA) stabilizing performance is not improved and, in some cases, an increase of wine turbidity could be induced; (b) for red wines with high colloidal instability, prior treatment with bentonite is recommended; (c) the application of potassium polyaspartate must be in accordance with the prescriptions of the International Oenological Codex.
