Istituto Marchigiano di tutela vini

Holds the official member register — the source of every producer linked to its denominations on this atlas.

The MASAF-recognised Istituto Marchigiano di tutela vini safeguards the integrity of its wine-growing heritage, representing a dedicated base of 480 verified producers on its official lists. This consortium actively protects several prestigious wine denominations, specifically overseeing Cònero DOCG, Castelli di Jesi Verdicchio Riserva DOCG, Verdicchio di Matelica Riserva DOCG, and Vernaccia di Serrapetrona DOCG. By maintaining official registries and promoting these distinct names, the consortium defends them from imitation, ensuring international enthusiasts experience only genuine wines from each protected denomination.
