Heineken, now the world's second largest beer maker, sold more beer than expected in the third quarter and retained its full-year profit margin forecast.

However the company said the impact of currencies would be worse than previously thought. 

The maker of Europe's top-selling lager Heineken, Tiger and Sol said it sold 2% more beer on a consolidated basis than a year earlier, with strong growth in Mexico and Asia, notably Vietnam.

But it saw lower volumes in Russia, Egypt and the Democratic Republic of Congo. 

Heineken also fared well in most European markets, due to favourable beer-drinking weather. 

Heineken has now become the world's number two brewer, although the gap between it global leader AB InBev has widened after the latter's takeover of SABMiller earlier this month. 

"Performance in the third quarter was robust despite strong comparatives in Americas and Europe, and a tough environment in Africa Middle East and Eastern Europe," chief executive Jean-Francois van Boxmeer said in a statement. 

Overall beer volumes were 54 million hectolitres, higher than the average expectation in a Reuters poll of 53.1 million.

The company said it still expected its operating margin would expand by about 40 basis points over the year, slowing down following a 124 point expansion in the first half. 

It did not give its margin for the third quarter. 

However, it forecast an even heavier currency translation impact, now at €215m at operating profit and €115m at net profit level, from €200m and €110m in previous predictions.
