Among these new releases from Frescobaldi, the 2015 Chianti Classico Gran Selezione Tenuta Perano Rialzi is my favorite wine. I liked this expression of Sangiovese from the Gaiole in Chianti subzone of the Chianti Classico appellation even more than the Brunello di Montalcino CastelGiocondo from the same vintage. The Frescobaldi team is more intimately familiar with farming in Montalcino, where they have been making wines for decades, than they are with the relatively newly acquired Tenuta Perano property. Buying this vineyard site was a very smart move, especially thanks to the gleaming white Albarese rocky soils present here. Those soils deal an unmistakable mineral note to the wine that adds sharpness, focus and brilliant linearity. In comparison, the Brunello has much broader shoulders and a heavier gait. This wine is fleeting, fragile and delicate. These are exactly the qualities you should look for in a single-vineyard Gran Selezione expression from this stirringly beautiful corner of Tuscany.
