Andrea Franchetti's 2017 Contrada R (from the Contrada Rampante) is the most volcanic and mineral-driven of these single-vineyard expressions. You taste the dusty volcanic soil as if you were holding it in your hands. Delicate berry and blueberry aromas fill in the rear. The wine shows some dryness with powdery tannins and a mid-weight but very compact mouthfeel. Of these wines, I would drink this bottle soonest. Production is 2,700 bottles small.
