The Langhe hills of Piedmont sit in the southern part of the Po Valley, where the foothills of the Maritime Alps meet the flatlands of northwestern Italy. The town of Alba sits at the center — Barolo's eleven communes spread to the southwest, Barbaresco's three communes lie to the northeast across the Tanaro river.
The map below is color-coded by dominant soil type. Warm tones indicate Tortonian soils — younger, more fertile, producing more approachable wines. Cool tones indicate Helvetian soils — older, more compact, producing the most structured and long-lived wines. Mixed zones sit between them. Click any commune to explore its full terroir profile.
