Annex I A to Regulation (EC) No 606/2009 is amended as follows:

(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:

‘Appendix 23 Requirements for the use of filter plates containing zeolites y-faujasite

The purpose of the use of a filter plate containing zeolites Y-faujasite applied during filtration is to reduce the concentration of haloanisoles responsible for off-flavour in wines, below their sensory perception threshold.

Prescriptions:

(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.

Appendix 24 Requirements for the treatment with potassium polyaspartate in wine

The purpose of the addition of potassium polyaspartate to wines is to contribute to the tartaric stabilization of wines.

Prescriptions:

(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.’
