SMERALDO S.S. di Giuseppe e Valter Azienda Agricola

Smeraldo works across three cornerstone Piedmont denominations, each demanding precision in the cellar. Ruchè di Castagnole Monferrato DOCG showcases the estate's command of this rare varietal, structured at minimum 12.5% alcohol from vineyards spanning seven municipalities. The portfolio extends to Barbera d'Asti DOCG—a wine requiring four months' aging—and Terre Alfieri DOCG, where both Arneis and Nebbiolo express the estate's breadth across white and red styles. This range reflects a producer calibrated to Piedmont's varietal identity and regulatory depth.
