Sherry

Sherry is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Sherry rather than just read about it. In short: Sherry (Spanish: Jerez [xeˈɾeθ]) 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…

Key takeaways

  • Sherry belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Sherry to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Sherry from memory before moving on to harder problems.

Reference excerpt

Sherry (Spanish: Jerez [xeˈɾeθ]) 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 Protegida (DOP). The word sherry is an anglicisation of Xérès (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 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 (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 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.

Worked examples

Example 1 — a first encounter with Sherry

Start with the simplest possible case. Write down what Sherry claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sherry before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sherry ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sherry

In research
Sherry appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Sherry in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Sherry is common in secondary-school and first-year university syllabi. It links to neighbouring topics Appellations, Jerez de la Frontera, Sherry, so understanding it makes those chapters shorter.
In everyday life
Look for Sherry outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Why does Sherry matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Sherry?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
