City of the Palmenti, Pietragalla, Italy

How did they make wine many years ago? Think you know? Well, let's take a tour of a city of ancient wineries dating back to the 1300s. The word Palmenti means an in-ground or below ground mill which could refer to rice, wheat or wine production. I was told that some of these were still in use ... but I doubt it. This is definitely off the usual tourist route.
