It can be hard to farm this soil type, but at the same time it is fascinating because of the vineyards set on steep hillsides, where it is difficult even to stand on. Winemakers have conquered the hills inch by inch, creating a particular scenery, so beautiful that Unesco has candidated the area as one of the World Heritage sites.
Vineyards are located only on the sunny sides of the hills, at an altidude between 50 and 500 meters above sea level, while the northern side is largely covered with woodland.
