Ceretto produces wines from Piemonte in northern Italy, drawing on the region's signature varieties. The winery's Nebbiolo-based Barolos—Rocche di Castiglione and Bricco Rocche—sit at the core of its portfolio, wines that have attracted attention from Wine Advocate, Wine Enthusiast, Wine Spectator, Decanter, and Falstaff. A Cabernet Sauvignon, La Bernardina, rounds out the lineup. Piemonte's continental climate and limestone-rich soils shape wines of structure and aging potential, qualities evident in these selections. The Rocche di Castiglione, in particular, reflects the precision and power that Nebbiolo demands from its terroir.
