Castagnoli produces Sangiovese-based wines from Chianti in central Tuscany. The winery's core expression, Chianti Classico, anchors a portfolio that extends to more concentrated offerings: Salita and Terrazze Chianti Classico Riserva both demonstrate the depth and structure that Sangiovese achieves in this region. The wines have been assessed by Decanter, Wine Advocate, Wine Enthusiast, and Wine Spectator. Chianti's continental climate and limestone-rich soils shape wines of clarity and aging potential, qualities evident across Castagnoli's range. The Terrazze Riserva, aged in oak, shows the traditional power of Chianti's finest bottlings, while the entry-level Chianti Classico offers direct access to the varietal's characteristic cherry, earth, and tannin profile.
