Scents of petrol, pineapple and lime mark the nose of the 2018 Riesling, which continues a long heritage of Smith-Madrone Rieslings. It's medium-bodied, just off-dry and intense, with ample concentration and a long, crisp finish. In a Napa Valley that has become increasingly focused on Cabernet Sauvignon (and the occasional Chardonnay), it's refreshing to find that these sorts of individual, characterful wines still exist.
