The Monteregio Di Massa Marittima DOC is a small wine production area just inland from the Tyrrhenian Sea and encircled by the larger Maremma Toscana DOC. Nearby are the Grosetto Metalliferous Hills, a vast architectural site whose iron rich soils impart the “terra rossa” in many of the vineyards. The DOC includes native vines such as Sangiovese, Trebbiano, Vermentino and Malvasia as well as Merlot, Cabernet Sauvignon, Syrah, Sauvignon Blanc, and Viognier.
