During the early 1990s new international wine laws to protect the traditional wine nomenclature within the EU were muted. The idea was to protect such terms as Claret, Burgundy, Champagne etc. but also the village & vineyard names within.
The treaty would include the non-EU wine countries would also classify and define terms and regions that would be protected.
The Australian Geographical Indication ‘Limestone Coast’ was entered in the Register of Protected Names on 27 December 1996 in response to a direction received by the Registrar from the Presiding Member of the Geographical Indications Committee acting under Section 40Z of the AWBC Act 1980. It really was re-naming the existing ‘South East of South Australia’ and to define using descriptive references.
