Quatr Nas is a blend of four varietals Nebbiolo, Cabernet Sauvignon ,Merlot and Pinot Noir. This wine was drinking very well last night. More like an aged Bordeaux but with loads of acidity. Wine has mellowed with the age but still improved with some time. Tannins has smoothed out but still grippy. Nebbiolo presents itself first with the strength and acidity, cab transitions to the merlot which provides some smoothness.
