Moving south, Italy is especially well-known for a huge diversity of wines, but one of the most famous and prestigious wine-growing areas in the country lies in its far northwest. Barolo, in the Piedmont region, is where the nebbiolo grape reigns supreme. Nebbiolo is a fickle, thin-skinned red varietal that requires very particular growing conditions, especially a gentle morning fog (nebbia in Italian, hence the grape's name). Many have tried to plant it throughout the world's wine regions, with almost complete failure—this grape truly gets homesick, and only wants to thrive in Italy's mountainous northern climes. The Vietti Barolo Castiglione Falletto 2011 is a gorgeous example. In its youth (as it is here), the wine is stony, with distinctive rose petal aromatics and downright aggressive tannins (beware!). Yet as it ages it develops beautiful earthy, tarry, truffle-like notes.
