Sherry Explained: Fino, Oloroso and the Solera
Sherry is the most misunderstood great wine in the world. Mention it and many people picture a sweet, oxidised drink in a dusty bottle — yet the finest Sherries are bone dry, electric with salt and acidity, and among the best value in fine wine. Made around the town of Jerez de la Frontera in Andalusia, Sherry is defined by two phenomena found almost nowhere else: a living veil of yeast called flor, and the fractional-blending system known as the solera.
The Sherry Triangle
Sherry comes from a defined zone in the far south-west of Spain, the "Sherry Triangle" between Jerez de la Frontera, Sanlúcar de Barrameda and El Puerto de Santa María. The defining soil is albariza, a brilliant white, chalk-rich earth that reflects the fierce Andalusian sun and retains winter rain deep below the surface. The Palomino grape, neutral and high-yielding, is the base of almost all dry Sherry.
Flor: the living veil
After the base wine is fermented dry and lightly fortified to around 15%, something extraordinary happens in the cask: a thick film of yeast, the flor, grows across the wine's surface. This living veil consumes oxygen, glycerol and acetic acid, protecting the wine from oxidation and giving it a piercing, savoury, almost briny character. Wines aged entirely under flor are "biologically aged"; those that lose their flor age oxidatively. This fork defines the whole range.
Fino and Manzanilla
The driest, palest, most delicate Sherries. Fino is aged under flor in the bodegas of Jerez and El Puerto; Manzanilla is the same style aged in the cooler, more humid coastal air of Sanlúcar de Barrameda, where the flor grows thickest and the wine takes on a distinctive saline tang. Both are best drunk fresh and lightly chilled, and they are sublime with the fried fish, olives and jamón of Andalusia.
Amontillado and Palo Cortado
When a Fino's flor eventually dies — naturally or by further fortification to around 17% — the wine begins to age oxidatively, deepening to amber and developing nutty, savoury complexity. This is Amontillado: a wine that began under flor and finished in air. Palo Cortado is a rare, prized accident — a wine with the finesse of an Amontillado and the body of an Oloroso, traditionally a Fino that lost its flor unexpectedly.
Oloroso
Fortified from the start to around 18% so that flor never forms, Oloroso ages entirely oxidatively, growing dark, rich and powerful with aromas of walnut, leather and dried fruit. It is naturally dry, despite its weight, and the finest old Olorosos are among the most concentrated wines in existence. Sweetened versions sold as "cream" Sherry are blends, not a natural style.
Pedro Ximénez and sweet styles
The great sweet Sherry is made from Pedro Ximénez (PX) grapes laid out in the sun to raisin, concentrating their sugar to staggering levels. Aged in solera, PX becomes almost black, viscous as treacle, tasting of fig, date, raisin and coffee. Moscatel makes a lighter sweet wine. These are dessert wines of extraordinary intensity, superb over vanilla ice cream.
The solera system
No vintage Sherry exists in the ordinary sense, because Sherry is blended across years by the solera. Casks are stacked in tiers; wine for bottling is drawn from the oldest tier (the solera proper), which is topped up from the tier above (the first criadera), and so on up the stack. Young wine is thus continually blended into old, producing a consistent house style and an average age that can reach decades — VOS and VORS designations indicate wines averaging over 20 and 30 years respectively.
The great bodegas
Jerez is dominated by historic houses with cathedral-like cellars. González Byass (home of Tío Pepe Fino), Lustau, Hidalgo-La Gitana (the Manzanilla benchmark in Sanlúcar), Barbadillo, Valdespino, Equipo Navazos and the legendary Bodegas Tradición all welcome visitors. A tour through the towering arched naves, with the flor visible on the wine, is one of the great wine-tourism experiences in Spain.
