Piedmont, meaning “foot of the mountain,” is the largest region of the Italian mainland, and it’s named for its mountains and rolling foothills. Although much of the region is too steep or cold for vines, the eastern and southern parts of the area are warm enough for grape growing. The tiny villages of Barolo and Barbaresco are renowned for their namesake wines made from the Nebbiolo grape, crafted into formidable, firm red wines idea for pairing with the richness of roast lamb or the region’s breathtakingly expensive white truffles.
