Compared to the Carricante from the Calderara Sottana cru, the 2017 Etna Bianco Santo Spirito (Cuvée delle Vigne Niche) is more mineral-driven in my opinion (by a small margin). Both wines were vinified and aged in the exact same way, so the very subtle differences you taste between the two are wholly territory-driven. The bouquet is crystalline and direct with briny sea aromas, summer peach and sun-dried lemon zest. Some 5,000 bottles were made.
