Which grape variety is commonly used to produce white wine in Chablis?

Chardonnay is the grape variety primarily used to produce white wine in Chablis, a renowned wine region in Burgundy, France. Chablis is famous for its high-quality Chardonnay wines that exhibit distinctive characteristics such as high acidity, steely minerality, and flavors of green apple, lemon, and sometimes a hint of flint. The region's unique geological and climatic conditions, including its limestone-rich soil and cool climate, contribute significantly to the flavor profile of the Chardonnay grown there.

The other grape varieties listed are more commonly associated with different regions or styles of wine. For instance, Riesling is primarily grown in regions like Alsace and Germany, where it produces aromatic, floral, and fruity wines. Sauvignon Blanc is well-known in regions such as the Loire Valley and New Zealand, noted for its herbaceous and citrusy notes. Pinot Grigio, often associated with Italy, tends to produce lighter, crisper wines with a different flavor profile compared to Chablis Chardonnay. Each grape variety has its unique terroir and characteristics, which are not representative of the white wines produced in Chablis.
