In the first half of 2014, beer sold by German breweries rose by 4.4 percent - an extra two million hectolitres or enough to fill 800 Olympic-sized swimming pools - compared with the same period of 2013. Brewers sold 47.9 million hectolitres in the first half of the year.
The Federal Statistics Office said on Thursday this rise was largely thanks to the World Cup, with the increase in sales mainly falling in June.
In the month the international football tournament began, sales increased by 14 percent to 9.7 million hectolitres - that was the best performance since 2010 - the year of the last World Cup.
Just over 80 percent of beer sold by German breweries was for domestic consumption. Domestic sales increased by 3.1 percent to almost 40 million hectolitres.
Exports soared by almost 11 percent with a 22 percent rise in sales to countries outside the EU.
The rise reverses a slow decline in German beer sales. In 2013, they sunk to their lowest level for almost 25 years. It was the seventh straight year of decline.
