Named for a north-to-south throughway that traverses Napa Valley, this blend of 82% Cabernet Sauvignon and 7% Cab Franc with small portions of Malbec, Petit Verdot, and Merlot exudes aromas of mint, cedar, and ripe blackberry. The nose mimics the palate, which sees the addition of a dusting of chocolate as well as violets and savory Italian herbs.
