This has to do with the fact that fracking does not stick soley to the only ingredients that may be used in the production of beer: Water, barley and hops. As a matter of fact, I don’t even think that fracking uses barley and hops at all.
I’m interested in tradition, too, of course. But let’s face it, if you’re going to start quoting a 500-year-old “purity law,” quote it right: The law also set the price of beer at 1-2 Pfennig per Maß.
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.
