Sherry Was Never Actually Invented
Sherry has the sort of reputation that makes people sit up straighter. It appears in tiny glasses, beside elderly relatives, often shortly before someone asks whether you have “settled down yet”. For decades, Britain treated it as the official drink of Christmas cupboards, suburban drinks trolleys and vicars who wanted something stronger than tea but less alarming than whisky.
Yet sherry did not begin as a sweet, brown beverage served at room temperature. Nor did a single inspired winemaker suddenly invent it after dropping brandy into a barrel. The real story stretches across roughly three thousand years and involves Phoenician traders, Roman exporters, Muslim farmers, Spanish growers, English merchants, pirates, war, yeast and a considerable amount of commercial improvisation. In other words, nobody invented sherry. Almost everybody interfered with it.
The story begins near modern Cádiz in southern Spain. Phoenician settlers established trading communities there around the beginning of the first millennium BC. They brought vines and winemaking knowledge from the eastern Mediterranean, then planted grapes in the pale, chalky soil around what later became Jerez.
That soil, called albariza, plays a surprisingly heroic role. It can contain a very high proportion of chalk, which gives the landscape its almost white appearance. During the wet winter, the porous ground absorbs water. Then, as the fierce Andalusian summer begins, the surface forms a crust that slows evaporation. The vines therefore survive months of heat with no irrigation and very little opportunity for melodrama.
The Phoenicians made wine in the region, but they did not make modern sherry. Their wine probably tasted heavier, rougher and more strongly preserved than anything now poured in a Jerez tasting room. Nevertheless, they established the essential habit: grow grapes in this peculiar corner of Spain and send the resulting wine somewhere else.
The Romans expanded that business enthusiastically. Wine from the area travelled throughout the empire, stored in amphorae and shipped from nearby ports. Roman writers praised the region’s agricultural products, while local growers refined cultivation and production. However, the wine still lacked the deliberate fortification, biological ageing and complex blending methods that define sherry today.
After the Islamic conquest of Iberia in the eighth century, the situation became more complicated. Popular mythology claims that Muslim rulers destroyed the vineyards because Islam prohibited alcohol. Reality, inconveniently, behaved with much less simplicity.
Vines remained useful even when wine consumption faced restrictions. Farmers produced raisins, table grapes, grape syrup and medicinal alcohol. Distillation knowledge also advanced across the medieval Islamic world, although the exact path from those techniques to fortified sherry remains difficult to trace. The vineyards around Jerez survived, adapted and continued supplying products that officials could defend with a sufficiently serious expression.
When Christian forces captured Jerez in 1264, wine production expanded again. The city became Jerez de la Frontera because it stood near the frontier between Christian and Muslim territories. Its wines increasingly travelled abroad, particularly towards northern Europe and England.
Here, language performed its usual tricks. The Arabic name Sherish evolved into the Spanish Jerez. English drinkers, apparently unwilling to wrestle with Spanish pronunciation before lunch, turned Jerez into “sherry”. For a time, they also called the wine “sack”, probably from the Spanish sacar, meaning to take out or export.
By the sixteenth century, England had developed a serious enthusiasm for the stuff. Shakespeare mentioned sack repeatedly, most famously through Falstaff, who praised it with the energy of a man who had clearly conducted extensive personal research. The drink of that period was not necessarily identical to modern sherry, but it came from the same region and already carried a powerful reputation.
Then Sir Francis Drake gave sherry one of history’s more aggressive marketing campaigns.
In 1587, Drake attacked Cádiz while Spain prepared the Armada. His forces destroyed ships, seized supplies and captured thousands of barrels of wine. Much of that wine reached England, where it apparently encouraged further interest in the Spanish drink. Spain viewed the raid as piracy. England regarded it as naval strategy. Wine merchants probably called it an excellent promotional event.
Fortification became increasingly important as overseas trade grew. Ordinary wine could spoil during long sea journeys, especially in warm conditions. Adding grape spirit raised the alcohol level and helped preserve the contents. Producers did not initially fortify every wine according to a single regulated formula. Instead, the practice evolved as merchants looked for ways to make wine more stable, more consistent and easier to ship.
This is where the myth of a single invention finally collapses. Fortification emerged gradually. So did the familiar styles of sherry. Producers, merchants and cellar masters learned by watching how different wines behaved in different barrels.
One of the strangest participants in this process was flor, a layer of yeast that forms naturally on the surface of certain wines. It protects the liquid from direct contact with oxygen and gives dry sherries such as Fino their sharp, fresh character, with notes often compared to almonds, bread dough and sea air.
For centuries, cellar workers may have regarded this floating yeast with suspicion. Mysterious biological films rarely inspire confidence, especially when sitting on top of something intended for paying customers. Gradually, however, bodegas recognised that flor could create distinctive and desirable wine.
Other barrels developed without that protective layer. Oxygen slowly transformed their contents, producing darker, richer and nuttier wines. These became the basis of styles such as Oloroso. Amontillado combined both journeys, beginning under flor before continuing with oxidative ageing. Palo Cortado, meanwhile, acquired a reputation as sherry’s mysterious rebel because it seemed to begin in one direction and finish in another.
Commercial pressure also shaped the solera system. Sherry merchants needed wines that tasted reasonably consistent from one shipment to the next. Vintage variation, although romantic, becomes less charming when customers expect the same product and receive something entirely different.
Producers therefore began blending older wine with younger wine through a system of fractional ageing. Barrels sit in groups according to age. Wine bottled from the oldest group gets replaced with wine from the next-youngest group, which receives wine from the group above it. The barrels never empty completely, so traces of older wines remain within the system.
People sometimes claim that a bottle from an ancient solera contains a meaningful quantity of wine from the year the system began. Technically, a tiny molecular trace might survive. Practically, nobody should imagine that half the glass once watched Napoleon march through Europe.
British families became deeply involved in the trade during the eighteenth and nineteenth centuries. Names such as Osborne, Williams, Humbert, Sandeman and Garvey reflected the international character of the Jerez business. English demand helped shape sweeter export styles, while merchants built vast cathedral-like bodegas designed to regulate temperature and encourage airflow.
That British influence created another lasting misunderstanding. Many people in Britain came to believe that all sherry tasted sweet because cream sherry dominated the mass market. In reality, several of the most traditional styles are extremely dry. A chilled Fino or Manzanilla can taste crisp, savoury and almost saline. It pairs naturally with olives, almonds, seafood, ham and tapas rather than sponge cake and polite family interrogation.
Sweet sherry certainly exists. Pedro Ximénez grapes can dry in the sun until they become intensely concentrated and raisin-like. The resulting wine may taste of figs, dates, coffee, treacle and dark chocolate. It can feel less like drinking wine and more like pouring a Victorian pudding into a glass.
Modern sherry now faces an awkward mixture of revival and decline. Overall consumption fell dramatically from its twentieth-century peak, and the drink still struggles against its elderly image in several markets. Yet sommeliers, specialist merchants and younger producers have revived interest in dry, old and vineyard-specific wines.
Meanwhile, climate change threatens the conditions that created sherry in the first place. Hotter temperatures can raise grape sugar and alcohol levels while placing stress on vineyards and complicating biological ageing under flor. Ironically, the region may need fresh innovation to preserve a drink built from centuries of adaptation.
Recent regulatory changes also reflect that pressure. The traditional definition of sherry has started to make more room for unfortified wines that naturally reach the required alcoholic strength. That sounds revolutionary until one remembers that wines from Jerez existed long before routine fortification. The future may therefore resemble the distant past, only with better temperature control and more paperwork.
Sherry’s invention was not a moment. It was an extended argument between landscape, microbes, merchants, politics and taste. The Phoenicians planted vines. Romans built trade. Muslim farmers preserved agricultural knowledge. Spanish growers refined the wine. British merchants helped turn it into an international product. Yeast floated on top and quietly changed everything.
Perhaps that explains why sherry remains so difficult to define. It can taste feather-light or almost syrupy, pale as straw or dark as mahogany, fiercely dry or extravagantly sweet. It belongs to Spain, yet foreign demand shaped it. Tradition protects it, although repeated reinvention kept it alive.
So the next time someone offers you a dusty bottle from the back of a cupboard, approach with cautious optimism. It may contain one of the world’s most fascinating wines. It may also have been open since 1997. History deserves respect, but not necessarily a second glass.
