In Ireland, the overall drinks market declined by two percent in the six months leading up to December 31. Diageo reports Guinness maintained their 32 percent share of the beer market, continuing to be the most popular pint on offer.
Net sales were flat in Europe as Diageo focus more on Africa, Latin America, and Asia Pacific, where sales now account for 40 percent of the business.
In response to the figures, Chief executive Paul Walsh said: ''We are cautious as to the consumer and economic trends we will face in 2012 but these first half results have positioned us well and they have demonstrated that Diageo has the brands, the routes to market and the people to deliver our medium term guidance."
