Which grape is often associated with the Cote d'Or region of Burgundy?

The grape most often associated with the Côte d'Or region of Burgundy is Pinot Noir. This area is renowned for producing some of the world's finest red wines, many of which are made exclusively from this varietal. The unique terroir of the Côte d'Or, with its distinctive soil types and microclimates, allows for the nuanced expression of Pinot Noir's characteristics—such as its vibrant acidity, fruit flavors (like cherry and raspberry), and earthy notes.

In contrast, Chardonnay is indeed a major varietal from Burgundy, particularly in areas like Chablis and the Côte de Beaune, but it is not the grape predominantly linked to the Côte d'Or's red wines. Cabernet Sauvignon and Merlot, while prestigious varieties, are primarily associated with regions like Bordeaux, rather than Burgundy. As a result, Pinot Noir is the correct choice, exemplifying the hallmark red wine of the Côte d'Or.
