Cipolla ramata di Montoro is an onion whose very name points to two neighbouring comunes, Montoro Superiore and Montoro Inferiore, in the province of Avellino. What draws the eye is the bulb’s outer tunic: a typical copper tone that, according to Regione Campania, is why the onion is called ramata. That metallic warmth on the skin is the detail that makes this particular onion worth a closer look.
The adjective ramato is not a flourish. It follows from the colour of that outer covering on the bulb, a copper cast that sits on the surface before any knife work begins. Peel it in the mind and the first impression is still that russet sheen, the reason the name sticks.
Keep the geography exact: the name is tied to those two Montoro comunes in Avellino, not to a wider claim about every onion in Campania. That place-name link is the useful orientation if you want to follow the product further among related Campanian listings.
