Declaration of Australia, South Africa and New Zealand

“In agreeing not to oppose the draft resolutions, Australia, South Africa and New Zealand wish to reaffirm their view that there are no current scientific, technical, health or safety reasons for establishing the proposed limits on the addition of organic acids to  wine or grape must.

Consistent with the production of balanced wines, minimising unnecessary regulation, including the additional costs of administering such regulation and ensuring such limits do not become effective barriers to trade, Australia, South Africa and New Zealand believe limits based on good manufacturing practice are the most appropriate”.
