Monterubiaglio is a paesello, a small hilltop village, below Castel Viscardo. The name Monterubiaglio literally means "red garlic mountain". Monterubiaglio has approximately 600 inhabitants, but during the summer time the population grows much larger as it is a popular vacation spot for persons who are originally from the village but may have moved elsewhere such as Rome.

Since 2006, the Department of Classics at Saint Anselm College has been excavating an Etrusco-Romano site just below Monterubiaglio. The excavation has yielded a number of finds and structures that date from the 8th century BCE to the 10th CE. 

Local agriculture is a primary industry, particular viticulture, and its production is part of the Orvieto wine-producing region, which is best known for the white wine Orvieto Classico. Lately, however, some wine growers have produced a new label "Monrubio", which is a red wine.
