Rocca di Frassinello was born from a high-profile partnership between Castellare di Castellina and Domaines Barons de Rothschild Lafite, uniting Tuscan intuition with Bordeaux discipline in the heart of Maremma. The project is not only viticultural but cultural, with the striking Renzo Piano-designed winery becoming a symbol of the estate ambition and modern outlook. From vineyard planning to cellar decisions, the brand has pursued a clear identity: wines with Mediterranean generosity, structural precision, and an elegant profile that can evolve beautifully over time.

Across its core labels, Rocca di Frassinello expresses the warm coastal climate, mineral-rich soils, and wide day-night temperature swings that define this part of southern Tuscany. The wines are regularly discussed in international tastings, restaurant programs, and specialist retail selections for their balance of depth and polish. As a result, the brand has earned a strong position among producers that represent the contemporary face of Maremma, combining prestige, consistency, and a style that appeals to both collectors and modern fine-wine audiences.
