Castelvecchi produces Sangiovese-based wines from Chianti, the heart of Toscana. The winery's portfolio centers on expressions of this classical region: Solana, a pure Sangiovese that has drawn attention from Wine Spectator, Decanter, Wine Enthusiast, and Wine Advocate; Madonnino della Pieve Gran Selezione Chianti Classico, a Sangiovese offering; and Capotondo Chianti Classico, which blends Sangiovese with Canaiolo Nero. These wines reflect the character of their terroir—Sangiovese's structure, acidity, and earthy minerality are hallmarks of Chianti's traditional style. The prestige critics' engagement with the winery's releases underscores their standing within the region's framework of quality production.
