Which two regions produce the Arneis grape?

The Arneis grape is primarily associated with the regions of Langhe and Roero, both of which are located in Piedmont, Italy. The Langhe region is known for its diverse wine production, including renowned wines made from Nebbiolo, but it also produces excellent white wines from the Arneis grape. Roero, another DOCG area, is particularly recognized for its high-quality Arneis, often leading to wines that are aromatic, fresh, and well-structured.

Choosing Langhe and Roero Arneis DOCG correctly identifies the traditional and recognized growing areas for this grape, which is less commonly associated with regions like Alto Adige or Gavi, which are known for other white varietals, or with the red wine-focused areas of Barolo and Barbaresco. Therefore, identifying the specific regions that produce Arneis reinforces the understanding of regional grape growing and the unique characteristics of Italian wine classifications.
