One of my favorite 'hidden gem' stops when showing people around Padova, where I lived, was taking them to the agricultural high school where my mother in law worked prior to retiring. Along with a working farm, they produced wine - and even grappa - there. It was actually pretty good, and if you bought it out of a tank rather than bottled it was very cheap.
Americans especially were quite amazed to see wine being produced and sold at a high school.
