The fall was largely blamed on economic weakness in some emerging markets and increasing regulations. Sales of sprits held largely steady at 0.3 per cent growth, although global vodka sales fell 4.3 per cent largely due to a 9.3 per cent fall in recession-hit Russia.
Sales of cider, which has been growing in popularity for several years, went backwards by 1.5 per cent last year due to a 15.2 per cent drop in US sales.
ISWR said the beer drop was mainly due to weakness in China, which is the world's biggest beer market by volume, but was also affected by other major economies. Beer sales fell 4.2 per cent in China, 5.3 per cent in Brazil and 7.8 per cent in Russia.
One bright spot was gin, with sales increasing by 3.7 per cent globally, largely led by strong European sales. Drinks giant Diageo, which owns Tanqueray gin, told the Financial Times per capita consumption of alcohol in the developed world had been dropping for three decades.
"However, there is a clear and sustained trend of consumers drinking better - not more," the company said. "This is supported in the IWSR data with the growth of global spirits, particularly whisky, gin and tequila."
