Sherry
Sherry is a fortified wine produced from white grapes grown around the city of Jerez de la Frontera in Andalusia, Spain. Sherry is a drink produced in a variety of styles made primarily from the Palomino grape, ranging from light versions similar to white table wines, such as Manzanilla and fino, to darker and heavier versions that have been allowed to oxidise as they age in barrel, such as Amontillado and oloroso. Sweet dessert wines are also made from Pedro Ximénez or Moscatel grapes, and are sometimes blended with Palomino-based sherries.
Under the official name of Jerez-Xérès-Sherry, it is one of Spain's wine regions, a Denominación de Origen. The word sherry is an anglicisation of Xérès. Sherry was previously known as sack, from the Spanish saca, meaning "extraction" from the solera. In Europe, "sherry" has protected designation of origin status, and under Spanish law, all wine labelled as "sherry" must legally come from the Sherry Triangle, an area in the province of Cádiz between Jerez de la Frontera, Sanlúcar de Barrameda, and El Puerto de Santa María. In 1933 the Jerez denominación de origen was the first Spanish denominación to be officially recognised in this way, officially named D.O. Jerez-Xeres-Sherry and sharing the same governing council as D.O. Manzanilla Sanlúcar de Barrameda.
After fermentation is complete, the base wines are fortified with grape spirit to increase their final alcohol content. Wines classified as suitable for aging as fino and Manzanilla are fortified until they reach a total alcohol content of 15.5 percent by volume. As they age in a barrel, they develop a layer of flor—a yeast-like growth that helps protect the wine from excessive oxidation. Those wines that are classified to undergo aging as oloroso are fortified to reach an alcohol content of at least 17 per cent. They do not develop flor and so oxidise slightly as they age, giving them a darker colour. Because the fortification takes place after fermentation, most sherries are initially dry, with any sweetness being added later. Despite the common misconception that sherry is a sweet drink, most varieties are dry. In contrast, port wine is fortified halfway through its fermentation, which stops the process so that not all of the sugar is turned into alcohol.
Wines from different years are aged and blended using a solera system before bottling so that bottles of sherry will not usually carry a specific vintage year and can contain a small proportion of very old wine. Sherry is regarded by some wine writers as "underappreciated" and a "neglected wine treasure".
History
Jerez has been a centre of viniculture since wine-making was introduced to Spain by the Phoenicians in 1100 BCE. The practice was carried on by the Romans when they took control of Iberia around 200 BCE. The Moors conquered the region in 711 CE and introduced distillation, which led to the development of brandy and fortified wine.During the Moorish period, the town was called Sherish, from which both sherry and Jerez are derived. Wines similar in style to sherry have traditionally been made in the city of Shiraz in mid-southern Iran, but it is thought unlikely that the name derives from there.
Wine production continued through five centuries of Muslim rule. In 966, Al-Hakam II, the second Caliph of Córdoba, ordered the destruction of the vineyards, but the inhabitants of Jerez appealed on the grounds that the vineyards also produced raisins to feed the empire's soldiers, and the Caliph spared two-thirds of the vineyards.
In 1264 Alfonso X of Castile took the city. From this point on, the production of sherry and its export throughout Europe increased significantly. By the end of the 16th century, sherry had a reputation in Europe as the world's finest wine. Christopher Columbus brought sherry on his voyage to the New World and when Ferdinand Magellan prepared to sail around the world in 1519, he spent more on sherry than on weapons.
By the time of the sixteenth century Cadiz became one of the most important Spanish seaports. In 1587 Spain was preparing an armada from there to invade England. Francis Drake, in a preemptive strike, sacked Cadiz that same year. After destroying the fleet, Drake brought back 2,900 barrels of sherry that had been waiting to be loaded aboard Spanish ships. This helped popularize sherry in the British Isles.
In the following centuries sherry was a major wine export to the United Kingdom, and thus many English companies and styles developed. Many of the Jerez cellars were founded by British families. In 1894 the Jerez region was devastated by the insect phylloxera. Whereas larger vineyards were replanted with resistant vines, most smaller producers were unable to fight the infestation and abandoned their vineyards entirely.
Types
- Fino is the driest and palest of the traditional varieties of sherry. The wine is aged in barrels under a cap of flor yeast to prevent contact with the air.
- Manzanilla is an especially light variety of fino sherry made around the port of Sanlúcar de Barrameda.
- Manzanilla Pasada is a Manzanilla that has undergone extended aging or has been partially oxidised, giving a richer, nuttier flavour.
- Amontillado is a variety of sherry that is first aged under flor and then exposed to oxygen, producing a sherry that is darker than a Fino but lighter than an Oloroso. Naturally dry, they are sometimes sold lightly- to medium-sweetened.
- Palo Cortado is a variety of sherry that is initially aged like an Amontillado, typically for three or four years, but which subsequently develops a character closer to an Oloroso. This either happens by accident when the flor dies or commonly the flor is killed by fortification or filtration.
- Oloroso is a variety of sherry aged oxidatively for a longer time than a Fino or Amontillado, producing a darker and richer wine. With alcohol levels between 18 and 20%, Olorosos are the most alcoholic sherries. Like Amontillado, naturally dry, they are often also sold in sweetened versions called Cream sherry.
- Jerez Dulce are made either by fermenting dried Pedro Ximénez or Moscatel grapes, which produces an intensely sweet dark brown or black wine, or by blending sweeter wines or grape must with a drier variety.

Trademark protection
Spanish producers have registered the three names Jerez / Xérès / sherry, and so may prosecute producers of similar fortified wines from other places using any of the same names. In 1933, Article 34 of the Spanish Estatuto del Vino established the boundaries of sherry production as the first Spanish wine denominación. Today, sherry's official status is further recognized by wider EU legislation, under which "sherry" sold within the EU must come from the triangular area of the province of Cádiz between Jerez de la Frontera, Sanlúcar de Barrameda, and El Puerto de Santa María. In the US, the name "sherry" is used as a semi-generic, and it must be labeled with a region of origin such as American sherry or California sherry; such wines cannot be legally exported to the EU.Both Canadian and Australian winemakers now use the term Apera instead of sherry, while consumers still use the term sherry.
Production
Climate
The Jerez district has a predictable climate, with approximately 70 days of rainfall and almost 300 days of sun per year. The rain mostly falls between the months of October and May, averaging. The summer is dry and hot, with temperatures as high as, but winds from the ocean bring moisture to the vineyards in the early morning and the clays in the soil retain water below the surface. The average temperature across the year is approximately.Soil
There are three types of soil in the Jerez district for growing the grapes for sherry:- Albariza: the lightest soil, almost white, and best for growing Palomino grapes. It is approximately 40 percent chalk, the rest being a blend of clay and sand. Albariza preserves moisture well during the hot summer months.
- Arenas: yellowish soil, also 10 percent chalk but with a high sand content.
- Barros: dark brown soil, 10 percent chalk with a high clay content.
The benefit of the albariza soil is that it can reflect sunlight back up to the vine, aiding it in photosynthesis. The nature of the soil is very absorbent and compact so it can retain and maximize the use of the little rainfall that the Jerez region receives.
