What are the three authorized grape varieties for sherry production?

The three authorized grape varieties for sherry production are Palomino, Pedro Ximenez, and Moscatel.

Palomino, the primary grape variety used in sherry, is known for producing dry and crisp wines that form the backbone of traditional fino and manzanilla sherries. Pedro Ximenez is famous for its sweet, rich wines, often used to create luscious dessert-style sherries. Moscatel adds aromatic characteristics to blends and can also produce sweet wines on its own. Together, these varieties encompass the essence of sherry, showcasing the unique terroir of the Jerez region in Spain.

Other options listed contain grape varieties not associated with sherry production. For instance, Tempranillo, Macabeo, and Garnacha are primarily used in the production of red and white wines in other regions of Spain, while Syrah, Zinfandel, and Chenin Blanc, as well as Merlot, Sangiovese, and Chardonnay, are varieties more commonly found in various other wine styles globally but are not legally permitted for producing sherry.
