Merlot, Cabernet Sauvignon, Cabernet Franc and some Petit Verdot make up the 2015 Bolgheri Rosso Il Seggio. The blend is aged in barrique, of which 70% is second-passage oak. Merlot is the largest part of the blend at 40%, and it is the grape you taste with the greatest distinction, especially in this warm vintage. The fruit comes from a vineyard site with strong iron content and other metals that add to the minerality of the wine. Il Seggio is the name of the river that brings these soil elements down from the hills. Indeed, there is a note of rusty nail on the close.
