What best describes the main difference between fino and oloroso sherry?

• A. Fino is a light, delicate, non-oxidized style; Oloroso is deliberately oxidized.
• B. Fino is aged in oak longer than Oloroso.
• C. Fino is sweet; Oloroso is dry.
• D. Fino is fortified; Oloroso is not.

Answer: (A)

The key idea is how aging exposure to oxygen is controlled. Fino stays protected by a thin layer of yeast called flor, which keeps oxygen out and preserves a pale, light, very dry style. Oloroso, on the other hand, ages without flor, so it oxidizes intentionally, taking on a darker color, fuller body, and richer, nutty character. That difference in oxidation is what creates the distinct profiles, not sweetness or fortification alone. Both are typically dry and both are fortified, so those aspects aren’t what separate them.
