La Grava (gravel) shows only modest differences from the silt, stone and sand wines in TintoNegro's soil-based series of 2012 Malbecs. Black-fruit aromas, herbal notes and solidity define the nose, while the palate is tight, juicy and racy, with red-fruit acidity. Nervy plum and raspberry flavors come with chocolaty oak and an agile, spicy finish. Drink through 2021.
