If a "Wawacity Beer" were to exist, it would likely follow these trends:
Warsteiner marketed itself heavily on the purity of its water, claiming the spring was pristine. In 2014, a German consumer protection agency ( Verbraucherzentrale ) sued Warsteiner, claiming the water wasn't as "virgin" as advertised because the brewery had to use UV light and filters to ensure safety. The court ruled that Warsteiner had to change its advertising, as the water did undergo some treatment (albeit minimal), debunking the myth that it was "untouched" water. wawacity beer
