Which of the following regions produces primarily Chenin Blanc?

The region that primarily produces Chenin Blanc is Anjou-Saumur. This area is located in the Loire Valley in France, which is renowned for its versatility and quality of Chenin Blanc wines. Anjou-Saumur encompasses a variety of styles, including dry, off-dry, and sweet wines, showcasing the adaptability of the Chenin Blanc grape to different vinification methods and terroirs.

In Anjou, for instance, the grape is often used to create some well-regarded dry whites as well as sweet dessert wines, particularly in regions such as Coteaux du Layon and Quarts de Chaume. The climatic conditions, along with the diverse soil types found in the region, contribute to the grape's development of complex flavors and characteristics.

In contrast, Chablis is known primarily for Chardonnay, Pouilly-Fumé is famous for Sauvignon Blanc, and Alsace primarily grows varietals such as Riesling and Gewürztraminer. Each of these regions has a signature grape or set of grapes that delineates its unique identity in the wine world, making Anjou-Saumur the clear choice for a region that specializes in Chenin Blanc.
