100% Montepulciano. Concrete Rosso comes from across all four of De Fermo's certified-biodynamic Montepulciano parcels where vines are about 25 years old; the fruit is hand-harvested later than that for Le Cince rosato and earlier than for the aged Prologo red. The bunches are destemmed, crushed and macerated for only 4-5 days, with the goal of a younger-drinking version of this very tannic grape. Fermentation is spontaneous with indigenous yeasts and no temperature control. The wine is aged in concrete tanks--hence the very literal name--for up to a year and bottled without fining or filtering; sulfur is used judiciously during racking but never at bottling. Since the wine is classified simply as Vino Rosso, the only geographical indicator on the bottle is "L.A." for the locale of Loreto Apruntino.
