I drink very little Italian wines and only limit to these few producers: Elio Altare, Clerico, and Paolo Scavino from Piedmont, Paolo Bea and Arnaldo Caprai from Umbria if I can find them!
Interrsting you like the Montefalco wines Chiu - beautiful place to visit.
Is it the Sagrantino you enjoy?
Myself I came to the conclusion I far preferred the Rosso de Montefalco wines with just a seasoning of the main grape.
Caprai make the most astonishing Olive oil should you visit/see it.
