Paolo Vergnano, son of the winery's founder Gianni, continues the mission of uncovering lesser-known but intriguing terroirs, aided by Giovanni Matteis and Gianpiero Gerbi. Their vineyards, which unfold in Castelnuovo Don Bosco, are rich in gray-blue clay marl, a characteristic that bestows volume and minerality to their wines. The primary grape here is freisa, especially on the Cornareto hill. Nearby, on the Schierano hill in Passerano Marmorito, malvasia, bonarda, and barbera dominate. The Albugnano Superiore Notturno '21, one of the appellation's best wines, stands out with its complex nose of red fruit and ginger. On the palate, it's succulent with a beautiful softness, culminating in a long, fresh finish. The captivating Barbera d'Asti Superiore Dedica '20 unveils aromas of red fruit and finely detailed spices, with a palate that's rich in fruit, beautifully balanced by acidity and a long finish. Other well-crafted wines include the Malvasia di Castelnuovo Don Bosco '22, which plays on tones of wild strawberry, and the Freisa d'Asti Il Forno '20, both fresh and abundantly fruity.
