100% Ruché. Mainly from estate parcels scattered about the steep hills of the Monferrato zone of Asti around the Verruàs' home village of Scurzolengo (there is some purchased Ruché in the mix too). The family farms organically, tending and harvesting the vines entirely by hand. The grapes are destemmed with berries kept whole and gently pressed without breaking the skins, just enough to kick off a native-yeast fermentation in vat. Fermentations go long in this cold cellar, as do macerations, which are up to 2 months. "Teresa" ages for a year in a mix of cement, fiberglass and steel tank before bottling without filtration. Zero sulfur. Verrua mama Maria Teresa's middle name and visage grace the label (artist: family friend Gianluca Cannizzo).
