Wine made under flor is a unique and distinctive style of winemaking, most famously associated with the Sherry region of Spain. Flor is a layer of yeast that naturally forms on the surface of the wine in the barrel, protecting it from oxidation and imparting complex flavors. Wines aged under flor, such as Fino and Manzanilla Sherry, develop a characteristic briny, nutty flavor with delicate hints of citrus and green apple. This process, known as biological aging, creates wines that are dry, crisp, and richly textured, celebrated for their depth and unique taste profile that reflects the influence of the flor yeast and the terroir where they are produced.
