Domenico Clerico is a figure in Piedmont. His Barolos are one of a small group of must-haves in the appellation along with Bruno Giacosa, Paolo Scavino, Armando Parusso, Luciano Sandrone and the three Conternos. Those who have not tasted these great Nebbiolo wines should remedy that as soon as possible, as they are perhaps, along with Cabernet Sauvignon, Pinot Noir and Syrah, the fourth most important red grape variety in the Four Aces.
