Typical of the south Vesuvius slopes, Nocerino spring onions are a variety of onion from the Allium Cepa L. species, and have been known and cultivated for over 2,000 years. It is presented with the characteristic elongated shape, the white onion bulb and thick and green leaves. The characteristics of the nocerino spring onion, like the San Marzano tomato, are exalted by the peculiar geo-pedological conditions in which it is cultivated. The volcanic soils of Agro Nocerino-Sarnese, in fact, combine with particularly favourable climatic conditions in the production of high quality agricultural products and inimitable organoleptic qualities, practically impossible to reproduce in greenhouses or other geographical areas. It is precisely this feature has allowed the nocerino spring onion to enjoy the DOP product classification.
