How is Sherry made?
Quick answer
Sherry might be the most underappreciated wine in the world. Made in a tiny corner of southern Spain (the 'Sherry Triangle'), it undergoes a winemaking process unlike anything else: a living layer of yeast called *flor* protects certain styles from oxygen, while others age fully exposed to air. The solera blending system — where young wine is fractionally blended with older wine across decades — creates consistency and complexity that no single vintage can match.
Detailed answer
Sherry is wine's best-kept secret — and its most misunderstood category. If you think it's your grandmother's dusty, sweet tipple, prepare to have your mind changed.
It all starts with Palomino Fino, a neutral white grape that produces unremarkable table wine but becomes extraordinary through Sherry's unique ageing processes.
**The flor miracle.** After fermentation, lighter wines are fortified to 15% and placed in barrels filled only five-sixths full. In the gap between wine and wood, a living blanket of yeast — called *flor* — forms on the surface. This flor protects the wine from oxidation while consuming glycerol (making it bone-dry) and producing acetaldehyde (that distinctive almond-and-green-apple aroma). The result: Fino and Manzanilla — pale, razor-sharp wines with intense salinity.
Manzanilla, aged exclusively in the coastal town of Sanlúcar de Barrameda, develops thicker flor due to higher humidity, producing wines with an unmistakable sea-breeze character. It's one of the most gastronomic wines in the world — stunning with seafood, olives, and jamón.
**Oxidative ageing.** Fuller-bodied wines are fortified to 17%, killing the flor. Oloroso ages exposed to air, developing rich nutty, caramel, and leather flavours. Annual evaporation (2-5%, called the 'angel's share') concentrates the wine further over decades.
**The in-betweens.** Amontillado starts as a Fino (under flor), then is fortified higher and finishes with oxidative ageing — combining both worlds. Palo Cortado is the mystery: classified as Fino but naturally developing Oloroso character. It's rare, prized, and impossible to produce on demand.
**The solera system** is what makes Sherry truly unique. Imagine rows of barrels stacked in a pyramid. Wine for bottling comes from the bottom row (oldest). That row is topped up from the row above, which is topped up from the row above that, and so on. No more than a third is ever drawn off at once. The result is a perpetual blend spanning decades — every bottle contains fractions of wine from every year the solera has been running.
