Langhe DOC is a wine appellation located in the Piedmont region of northwestern Italy, encompassing the rolling hills around the towns of Alba, Barbaresco, and Barolo. Established as a DOC in 1994, this designation covers a broad area within the famous Langhe hills, which are part of the larger Cuneo province. The appellation was created to provide greater flexibility for producers working with both traditional Piedmontese varieties and international grape types.

The Langhe hills feature a continental climate with hot summers and cold winters, moderated by maritime influences from the distant Mediterranean. The diverse soils range from calcareous clay to sandy formations, creating varied microclimates across the zone. The DOC regulations permit a wide range of grape varieties, including traditional Piedmontese grapes like Nebbiolo, Barbera, and Dolcetto, as well as international varieties such as Chardonnay, Sauvignon Blanc, Cabernet Sauvignon, and Merlot. This flexibility allows producers to create both varietal wines and blends under the Langhe designation.

Langhe DOC wines reflect the diverse terroir and grape varieties permitted within the appellation. White wines from varieties like Chardonnay and Sauvignon Blanc often display mineral complexity with good acidity, while maintaining the elegance characteristic of high-altitude Piedmontese vineyards. Nebbiolo-based reds from this appellation tend to be more approachable than their Barolo and Barbaresco counterparts, offering the variety's signature floral aromatics and structured tannins in a style designed for earlier consumption.
