Superiore or Superior is the term given in Italy to DOC and DOCG wines to indicate a higher alcohol content than the generic wine and a mandatory minimum ageing. The Superiore guidelines adhere to the same legislative standards of the Riserva ones. Compared to the generic or entry-level wine, wines with the Superiore denomination are typically aged at least one year and have a higher alcohol content (+0.5%). Depending on each disciplinare, protocol, there could be a requirement for a longer aging period and a different higher yield per hectare than those mandated for generic wine. Note that the Superiore qualification cannot be matched to the Riserva and Novello denominations. Examples of Superiore wines include: Barbera d’Asti Su- periore, Barbera d’Alba Superiore, Valtellina Superiore, Frascati Superiore, and more.
