Mostly Cabernet Sauvignon, with a little Cab Franc, Merlot, and Petit Verdot, all from the alluvial soils of the old Tocornal estate, where the Andean foothills meet the Alto Maipo.
"This vineyard is on a west-facing slope, above the fog line, on the northern ridge of the Atlas Peak AVA. The Hambright and Guenoc soils are dominated by red volcanic material with lots of flat rock, providing exceptional drainage to the hillside vineyard."
