(TheDrinksBusiness) - Growth in the luxury goods market, including fine wines, Champagne and premium spirits, is slowing. Growth in the luxury goods market including fine wine and Champagne is slowing downThat is the message from an authoritative survey from Bain & Co, the international consultancy and reflected in the latest figures from global drinks producers. Bain says the imminent change in China’s government is causing uncertainty among the country’s growing middle class, who are moderating their spending and giving fewer gifts than otherwise they might. In 2010 and 2011 demand for luxury goods in China grew by an eye-watering 30% and 35% respectively, but this year it will slow to 18% as the country’s overall economy decelerates from frenetic double-digit annual growth rates to a more sustainable rate of about 7%.
