From Trás-os-Montes, Viosinho is a grape variety that offers very low outcome, which helps to explain such low popularity among most of the winegrowers. Even though it is not a deeply aromatic variety, it offers a near-perfect balance between sugar and acidity that gives rise to structured, full-bodied wine and potentially rich in alcohol. Customarily the wine is structured and powerful, although sometimes with some lack of vigor and freshness.
