The winery Santiuorio is the most important part of the company Erminio Covino. It transforms the grapes of their vineyards occupying part of the hilly terrain of Tingi, Zì Iannaro, Paramenti and Santiuorio.

In addition to apple orchards, the company produces various qualities of cherries, hazelnuts, walnuts, peaches, pears, olives and vegetables.

The core of the company is made ​​up of the old farm of Antonio Franco, taken up by the Covino family in the early 30’s of last century.

Not less important is the hilly area for its morphology and structure of the soil that allows the development of a rich and varied vegetation: not only chestnut and oak but also olives, vines and other fruit trees. The whole area has a long history, as evidenced by the Caudine Forks, scene of military clashes between Samnites and Romans and the National Archaeological Museum of Montesarchio, which houses priceless artefacts.

The company, currently managed by Erminio Covino, is the continuation of the centurial experiences of grandfather Eminio and uncle Pietro, of which keeps even the old customs of hospitality.
