Which Sherry style is traditionally dry and served chilled?

Fino is the correct answer because it is the lightest and driest style of Sherry, characterized by its pale straw color and delicate flavors. It undergoes a process known as flor aging, where a natural yeast film develops on the surface of the wine, protecting it from oxidation and imparting distinctive aromas of almond and fresh bread.

Traditionally, Fino is served chilled, making it a popular choice as an aperitif, particularly during warm weather. This style of Sherry is best enjoyed young and fresh, which accentuates its crispness and enhances the refreshing qualities that pair well with a variety of dishes, especially seafood and tapas.

In contrast, Oloroso is typically a richer and fuller-bodied style that is often sweeter and not served chilled. Amontillado starts off as a Fino but undergoes additional aging without flor, gaining a nuttier profile and a darker color; it's also typically served at a slightly warmer temperature. Pedro Ximénez is a very sweet and dark dessert sherry made from sun-dried grapes, also not served chilled, but rather at room temperature to emphasize its rich, sweet flavors.
