Verdicchio dei Castelli di Jesi Riserva is a relatively recent addition to Italy`s prestigious DOCG designations, established in February 2010. This classification is reserved for the highest-quality Verdicchio dry white wines that were previously marketed under the DOC Verdicchio dei Castelli di Jesi. All Riserva DOCG wines must undergo ageing for a minimum of 18 months prior to their release.
