Sherry (English //, Spanish: Jerez [xeˈɾeθ] or [xeˈɾes]) is a fortified wine made from white grapes that are grown near the town of Jerez de la Frontera in Andalusia, Spain. Sherry is produced in a variety of dry 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 Ximenez or Moscatel grapes, and are sometimes blended with Palomino-based Sherries.
The word "Sherry" is an anglicisation of Xeres (Jerez). 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 in order 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 per cent by volume. As they age in 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. In contrast, Port wine, for example, 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 many wine writers as "underappreciated" and a "neglected wine treasure".
Jerez has been a centre of viniculture since wine-making was introduced to Spain by the Phoenicians in 1100 BC. The practice was carried on by the Romans when they took control of Iberia around 200 BC. The Moors conquered the region in AD 711 and introduced distillation, which led to the development of brandy and fortified wine.
During the Moorish period, the town was called Sherish (a transliteration of the Arabic شريش), 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 Arab Empire's 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.
Sherry wine became very popular in Great Britain, especially after Francis Drake sacked Cadiz in 1587. At that time Cadiz was one of the most important Spanish sea ports, and Spain was preparing an armada there to invade England. Among the spoils Drake brought back after destroying the fleet were 2,900 barrels of Sherry that had been on shore waiting to be loaded aboard Spanish ships. This helped to popularize Sherry in the British Isles.
Because Sherry was a major wine export to the United Kingdom, 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.
On 12 April 2012, the rules applicable to the sweet and fortified Denominations of Origen Montilla-Moriles and Jerez-Xérès-Sherry  were changed to prohibit sweet Oloroso and sweet Amontillado banning terms such as "Rich Oloroso", "Sweet Oloroso" and "Oloroso Dulce". Such wines are to be labelled as "Cream Sherry: Blend of Oloroso / Amontillado" or suchlike. The classification by sweetness is:
|Fortified Wine Type||Alcohol % ABV||Sugar content|
(grams per litre)
|Dulce / Sweet||15–22||160+|
Spanish producers have registered the names Jerez / Xérès / Sherry and will prosecute producers of similar fortified wines from other places using the same name. In 1933, Article 34 of the Spanish Estatuto del Vino (Wine Law) established the boundaries of Sherry production as the first Spanish wine denominación. Today, Sherry's official status is further recognized by wider EU legislation. Sherry 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. However the name "Sherry" is used as a semi-generic in the United States where it must be labeled with a region of origin such as American sherry or California sherry. However such wines cannot be exported to the EU. Australian wine makers now use the term Apera instead of Sherry, whilst Australian consumers still use the term Sherry. As of December 31, 2013 the term Apera is now also used by Canadian wine makers.
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 600 l/m². The summer is dry and hot, with temperatures as high as 40 °C (104 °F), 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 18 °C (64 °F).
The albariza soil is the best for growing the Palomino grape, and by law 40 per cent of the grapes making up a Sherry must come from albariza soil. The barros and arenas soil are mostly used for Pedro Ximénez and Moscatel grapes.
The benefits 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 that it can retain and maximize the use of the little rainfall that the Jerez region receives.
Before the phylloxera infestation in 1894, there were estimated to be over 100 varieties of grape used in Spain for the production of Sherry, but now there are only three white grapes grown for Sherry-making:
Sherry-style wines made in other countries often use other grape varieties.
The Palomino grapes are harvested in early September, and pressed lightly to extract the must. The must from the first pressing, the primera yema, is used to produce Fino and Manzanilla and the must from the second pressing, the segunda yema will be used for Oloroso ; the product of additional pressings is used for lesser wines, distillation and vinegar. The must is then fermented in stainless steel vats until the end of November, producing a dry white wine with 11–12 percent alcohol content.
Immediately after fermentation, the wine is sampled and the first classification is performed. The casks are marked with the following symbols according to the potential of the wine:
|/||a single stroke indicates a wine with the finest flavour and aroma, suitable for Fino or Amontillado. These wines are fortified to about 15 percent alcohol to allow the growth of flor.|
|/.||a single stroke with a dot indicates a heavier, more full-bodied wine. These wines are fortified to about 17.5 percent alcohol to prevent the growth of flor, and the wines are aged oxidatively to produce Oloroso.|
|//||a double stroke indicates a wine which will be allowed to develop further before determining whether to use the wine for Amontillado or Oloroso. These wines are fortified to about 15 percent alcohol.|
|///||a triple stroke indicates a wine that has developed poorly, and will be distilled.|
The Sherry is fortified using destilado, made by distilling wine, usually from La Mancha. The distilled spirit is first mixed with mature Sherry to make a 50/50 blend known as mitad y mitad (half and half), and then the mitad y mitad is mixed with the younger Sherry to the proper proportions. This two-stage procedure is performed so the strong alcohol will not shock the young Sherry and spoil it.
The fortified wine is stored in 500-litre casks that are made of North American oak, which is less porous than French or Spanish oak. The casks, or butts, are filled five-sixths full, leaving "the space of two fists" empty at the top to allow flor to develop on top of the wine.
Sherry is then aged in the solera system where new wine is put into wine barrels at the beginning of a series of three to nine barrels. Periodically, a portion of the wine in a barrel is moved into the next barrel down, using tools called the canoa (canoe) and rociador (sprinkler) to move the wine gently and avoid damaging the layer of flor in each barrel. At the end of the series only a portion of the final barrel is bottled and sold. Depending on the type of wine, the portion moved may be between five and thirty percent of each barrel. This process is called "running the scales" because each barrel in the series is called a scale. Thus, the age of the youngest wine going in the bottle is determined by the number of barrels in the series, and every bottle also contains some much older wine than is stated. Sherry is aged in the solera for a minimum of 3 years.
Once bottled, Sherry does not generally benefit from further ageing and may be consumed immediately, though the sherries that have been aged oxidatively may be stored for years without noticeable loss in flavour. Bottles should be stored upright to minimize the wine's exposed surface area. As with other wines, Sherry should be stored in a cool, dark place. The best fino sherries which have been aged for longer than normal prior to bottling, such as Manzanilla Pasada, will continue to develop in the bottle for some years.
Fino and Manzanilla are the most fragile types of Sherry and should usually be drunk soon after opening in the same way as unfortified wines. In Spain, Finos are often sold in half bottles, with any remaining wine being thrown out if it is not drunk the same day it is opened. Amontillados and Olorosos will keep for longer, while sweeter versions such as PX, and blended cream Sherries, are able to last several weeks or even months after opening, since the sugar content acts as a preservative. This robustness led NASA to buy some Paul Masson Californian Rare Cream "Sherry" for a Skylab mission in the 1970s. They packaged some for testing on a "zero-G" aircraft but the smell quickly permeated the cabin making astronauts physically sick, and public pressure over taking alcohol into space led NASA to abandon their plans.
Sherry is traditionally drunk from a copita, a special tulip-shaped Sherry glass. Sampling wine directly from a Sherry butt may be performed with characteristic flourish by a venenciador, named after the special cup (the venencia) traditionally made of silver and fastened to a long whalebone handle. The cup, narrow enough to pass though the bung hole, withdraws a measure of Sherry which is then ceremoniously poured from head height into a copita held in the other hand.
There are many literary figures who wrote about Sherry: William Shakespeare, Benito Pérez Galdós, Alexander Fleming and Edgar Allan Poe (in his story "The Cask of Amontillado"). Famous Indian cricketer and politician Navjot Singh Sidhu's nickname is Sherry after the wine named so by his father.
