A malfunction at a local winery caused 1,000 liters of ready-to-be-bottled wine to leak into the water pipes. The glitch lasted about three hours and impacted about 20 homes, said Giorgia Mezzacqui, deputy mayor of Castelvetro, about 10 miles south of Modena. The local government posted on its Facebook page that the leak didn't pose any health risks. The malfunction was caused by a faulty valve in the washing circuit within the bottling line. Lambrusco Grasparossa, a local specialty, seeped through the town's water lines due to its pressure, the winery said in a statement obtained by CNN.
