Which appellation can put its name in front of the term Côtes de Bordeaux for recognition?

The appellation that can put its name in front of the term Côtes de Bordeaux is Blaye. This region is part of the Bordeaux wine area and is recognized for its ability to produce high-quality red and white wines. When Blaye is referred to with "Côtes de Bordeaux," it emphasizes the area’s unique characteristics and enhances its identity within the broader Bordeaux classification.

In contrast, the other options refer to distinct wine regions with their own specific classifications that do not fit within the Côtes de Bordeaux terminology. For example, Chablis is a renowned region in Burgundy known for its Chardonnay wines but does not have a connection to the Côtes de Bordeaux. Similarly, Burgundy itself is a major wine-producing region, focusing on its specific appellation system, and Champagne is recognized globally for its sparkling wines, which are not part of the Bordeaux classification. Each of these regions has its own unique identity, separate from the Côtes de Bordeaux system, which highlights local wine styles and regulations specific to Bordeaux.
