100% Ruche. 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. The wine ages for a year in a mix of cement, fiberglass and steel tank. At this point, the wine is either bottled the annual "Teresa" (named for mama Maria Teresa Verruà) or, in certain vintages, aged another full year in a large botte before being bottled as "Teresa La Grande". No filtration and zero sulfur. The most recent vintages have been 2015, 2016, 2020 and 2021 (not released yet).
