(Decanter) - The value of bottled wine exports from Western Australia – excluding the Margaret River appellation – fell by 41% in 2012, Wine Australia has revealed. Bottled wine exports from the region fell from AUS$12.9m to AUS$7.6m, according to the December 2012 Wine Export Approval Report released this month. Margaret River was the only appellation that had shown an increase in export value, rescuing the region from recording an overall decline.
