Wine Advocate-Parker : Sangioveto (otherwise known as Sangiovese) is enhanced with smaller parts Merlot and Cabernet Sauvignon to make the 2015 Maremma Toscana Rocca di Frassinello. This wine is showing improved results as the estate's vines grow in age and, consequently, in complexity with each passing year. Fermentation occurs in stainless steel tanks, and the wine later ages in barrique for 14 months. It shows enormous richness and power that is delivered in a happily balanced manner, thanks to the ripe and opulent nature of the fruit in this vintage. There is a point of sweetness followed by dark fruit flavors and balanced spice. This wine will continue its evolution over the better part of the next decade.
