Which of the following is not a Beaujolais Cru?

Fleurie, Morgon, and Cru Beaujolais are all recognized as part of the Beaujolais Crus, which are specific regions within the Beaujolais wine-producing area known for high-quality wines. Each of these areas has its distinctive characteristics and styles, contributing to the diversity of wines in the Beaujolais region.

St. Denis, on the other hand, is not a recognized Beaujolais Cru. It does not belong to the official list of Crus defined by the region's regulatory body. Instead, it is often associated with either the Côte de Nuits (part of the Burgundy region) or may be confused with other regions that are not part of the Beaujolais designation. Recognizing the distinctions between the Crus is essential for understanding the hierarchy and quality classifications of wines from this area.
