The performance of vintage champagne was set at 9700 kilograms per hectare, down almost 25% compared to 2008. These measures have been taken in response to falling sales and to enable destocking, said Interprofession thursday. "There are 1.2 billion cellar bottle. By limiting performance, it aims to balance supply and demand does not increase the stock level already high," said Daniel Lorson, communications director of the Interprofessional Wine Champagne Committee (IWCC.) In 2008, the yield was set to 13,000 kg per hectare, the equivalent of 373 million bottles.
