55% Nebbiolo/30% Croatina/10% Vespolina/5% Uva Rara. Unlike the Lozio red, the Santuvario red is able to be made annually, from Ivano's younger (20-to-40-year-old) vines in both Boca and nearby Maggiora, on 400m-high sites in the middle of the woods on porphyry-rich volcanic soils. Ivano works the vines organically and by hand, including manual harvest. The fruit is destemmed and fermented with native yeasts in stainless steel tank with a two-week maceration. The wine is aged in a single 1700-liter Austrian oak cask for one year and then for another year in bottle before release.
