Named in keeping with the classical musical theme and the number of grape varieties in the blend, Marietta's 2020 Quartet is 48% Merlot, 46% Cabernet Sauvignon, 5% Cabernet Franc and 1% Petit Verdot, with some 90% of the total coming from Carneros. The nose features hints of black olives and faintly herbal nuances set against a core of black cherries. Meant to be approachable young, it's medium to full-bodied, easy to drink and silky in feel, with ample length.
