Heineken, the world's third-largest brewer, sold more beer than expected in the first quarter and persuaded consumers to switch to premium brands, helping its shares to a four-year high.

Europe's largest beermaker said on Wednesday beer volume grew 4.7 per cent on a like-for-like basis, with revenue up 6.8 per cent. Volume growth was more than double the rate the market had expected.

Analysts said that while Heineken had benefited from mild winters in much of Europe and North America, an early Easter and an extra leap-year day, volume and revenue growth were still impressive. Revenue per hectolitre increased 3.5 per cent.

Trevor Stirling, analyst at Bernstein Securities, said he was most encouraged by the 4.5 per cent volume growth in the Americas, with improvements for the Heineken brand in the United States and growth in Mexico, where it bought the second-largest brewer FEMSA Cerveza in 2010.

"There was scepticism about the quality of the business they bought there and the ability of Heineken to pull it around. It looks like they are proving the sceptics wrong," he said.

The Dutch company's shares were up 4.0 per cent to 44.00 euros at 0915 GMT, after hitting its highest level since January 2008.

Heineken said its higher revenue and cost savings were partly offset by increased fixed costs in certain high- inflation markets, investments and increased raw material costs, such as barley.

With a further 23 million euro charge for non-completion of a planned sale of a Chinese brewer, operating profit before one-off items declined slightly. It did not give a precise figure.

Heineken, for whom western Europe makes up 45 per cent of revenue, stuck to the outlook it issued in February. That expected growth in the emerging markets it is pushing into in Africa, Latin America and Asia.

It also said marketing and selling expenses would be in line with those of 2011 as it expanded its brands Desperados, Strongbow, Amstel and Sol. Higher malted barley prices would push up input costs by about 6 per cent.

Heineken aims to offset the greater costs by a mix of selling more beer at higher prices and with a new 500 million euro cost savings plan running until 2014.

Heineken is the first of the big four brewers to report results for the first three months of 2012.
