No, it was not a prelude to the second coming of Jesus, but a malfunction on the Lambrusco Grasparossa bottling line of Cantina Settecani Castelvetro's winery. 
Lambrusco Grasparossa is a type of sparkling red wine that is popular in the area.
The unfortunate mix-up occurred when one of the wine silos began leaking into the water pipe supply in the village of Settecani due to the high pressure, and ran through the mains network into nearby houses, according to Unilad.
Local authorities shared a message on their Facebook page explaining that the technical fault had been resolved and did not carry any hygiene or health risks.
The winery also apologized in a Facebook post, explaining there was an issue with a circuit valve on the bottling line and stressed the problem was quickly fixed.
Although Residents and commentators were amused by the incident.
