In the early 90s, while continuing the process of enhancing of the typicality of the varietal grapes and wines, linked to the territory, Antonio and Raffaele found out in the Coda di Volpe "cultivar", particularly widespread in the province of Avellino, no longer a blending grape, as required by the product specification of Greco di Tufo, but a grape variety from which a IGT wine worthy to have its own bottle and label. Then, the selections in limited quantity came, the Greco di Tufo "Vigna Federico II" and Fiano di Avellino "Vigna Arechi", from long aging in bottle, with organoleptic and physico–chemical features of considerable quality to be enjoyed after a few years.
