It appears that the growing demand for Champagne has left wine growers in the region struggling to cope. Annual sales have now grown to £7 billion meaning that French authorities are considering expanding the region in which wine growers are allowed to make Champagne. Currently 317 villages have been judged to have the right soil and weather conditions that are needed to produce grapes of sufficient quality to make Champagne. The boundaries are now likely to be redrawn to include a further 40 villages which will start producing Champagne within ten years. Last year the British were the biggest Champagne drinkers outside of France, consuming 39 million bottles.
