"German brewers have warned Chancellor Angela Merkel's government that any law allowing the controversial drilling technique known as fracking could damage the country's cherished beer industry."
"The Brauer-Bund beer association is worried that fracking for shale gas, which involves pumping water and chemicals at high pressure into the ground, could pollute water used for brewing and break a 500-year-old industry rule on water purity.
Germany, home to Munich's annual Oktoberfest - the world's biggest folk festival which attracts around 7 million visitors - has a proud tradition of brewing and beer drinking.
Under the 'Reinheitsgebot', or German purity law, brewers have to produce beer using only malt, hops, yeast and water."
