Bordeaux winemakers have unanimously rejected French government proposals to split the existing AOC category in two.

The proposed names for the new categories were IOC (Indication d'Origine Contrôlée and AO (Appellation d'Origine), with the categories having different rules on winemaking techniques.

"The vote was unanimous against any split of the AOC category," said Conseil Interprofessionnel du Vin de Bordeaux (CIVB) director, Roland Feredj, who was at the vote on Tuesday (16 January).

The meeting also called for French winemakers to have access to all winemaking methods available to producers worldwide.

French AOC winemakers are limited in the oenological techniques they can use to make wine. The Institut National des Appellations d'Origine (INAO), the regulatory body for AOC wines, recently banned, for example, the use of wood chips in AOC winemaking.
