In prison, illegally produced alcohol is sometimes referred to as "toilet wine.".But in Alabama, authorities found an illegal winemaking operation so large, it needed an entire sewage plant.Law enforcement raided the Rainsville Wastewater Treatment Plant after getting a tip about the winemaking.Authorities said they found a large wine production operation that appeared to have been in use for quite some time.The operation was housed in a little-frequented part of the facility.No numbers were given on the size of the operation, but images appear to show at least 300 bottles worth of wine.Allen Maurice Stiefel, a supervisor, was charged with unlawful possession of an illegally manufactured alcoholic beverage.Fortunately, it was reported that wastewater was not used to make the booze.But even with that said, how good can wine made in a rural Alabama sewage treatment plant really be?
