Oseleta, an ancient Veronese grape variety, was rediscovered and replanted by Masi in the 1980s after years of oblivion. Today, it is grown again in three different vineyards, selected by the Masi Technical Group as ideal for the cultivation of this particular variety:
- The vineyard in Valgatara is at the bottom of the valley on alluvial soil and trained in the bilateral pergola fashion.
- The vineyard in Gargagnago is part of the Serego Alighieri property and its soil is composed of a deep deposit of principally calcareous layers. The one-sided Guyot system is used for vine training here.
- The Pol vineyard lies in the commune of Bussolengo, alongside the River Adige, and benefits from a mild climate refreshed by breezes from nearby Mount Baldo. This vineyard has tufaceous soil, volcanic limestone in origin, and is trained in the one-sided Guyot fashion. The Oseleta grape variety is used to make structured and complex reds such as Toar and Osar, as well as being used to add personality to the blends of other Masi wines.
