TENUTA MARENGO S.S. Agricola
Barbera d'Asti DOCGRuchè di Castagnole Monferrato DOCGTerre Alfieri DOCG
Tenuta Marengo operates as a fully organic estate rooted in nineteenth-century Piedmont, where three DOCG designations—Ruchè di Castagnole Monferrato, Terre Alfieri, and Barbera d'Asti—frame its portfolio. The vineyard's isolation from neighboring cultivation eliminates chemical drift, a defining advantage for preserving purity. Here, winemaking honors historical methods without the chemical shortcuts of earlier eras, producing wines where soil integrity and flavor authenticity converge across reds and whites that meet rigorous minimum alcohol and aging standards.
