Maderisation
Maderisation is a process that involves the heating and oxidisation of a wine. The term is named after the process used in the production of Madeira wine, where it occurs while the wine is in cask. The resulting wine darkens in color and acquires a Sherry-like character. Outside Madeira wine, it is generally seen as a wine fault, but is desirable in the case of certain dessert wines where it occurs over the course of long bottle aging Ageing ( BE) or aging ( AE) is the process of becoming older. The term refers mainly to humans, many other animals, and fungi, whereas for example, bacteria, perennial plants and some simple animals are potentially biologically immortal.

Redox
Redox (reduction–oxidation, , ) is a type of chemical reaction in which the oxidation states of substrate (chemistry), substrate change. Oxidation is the loss of Electron, electrons or an increase in the oxidation state, while reduction is the gain of electrons or a decrease in the oxidation state. There are two classes of redox reactions: * ''Electron-transfer'' – Only one (usually) electron flows from the reducing agent to the oxidant. This type of redox reaction is often discussed in terms of redox couples and electrode potentials. * ''Atom transfer'' – An atom transfers from one substrate to another. For example, in the rusting of iron, the oxidation state of iron atoms increases as the iron converts to an oxide, and simultaneously the oxidation state of oxygen decreases as it accepts electrons released by the iron. Although oxidation reactions are commonly associated with the formation of oxides, other chemical species can serve the same function. In hydrogen ...

Madeira Wine
Madeira is a fortified wine made on the Portuguese Madeira Islands, off the coast of Africa. Madeira is produced in a variety of styles ranging from dry wines which can be consumed on their own, as an apéritif, to sweet wines usually consumed with dessert. Cheaper cooking versions are often flavoured with salt and pepper for use in cooking, but these are not fit for consumption as a beverage. The islands of Madeira have a long winemaking history, dating back to the Age of Exploration (approximately from the end of the 15th century) when Madeira was a standard port of call for ships heading to the New World or East Indies. To prevent the wine from spoiling, neutral grape spirits were added. On the long sea voyages, the wines would be exposed to excessive heat and movement which transformed the flavour of the wine. This was discovered by the wine producers of Madeira when an unsold shipment of wine returned to the islands after a round trip. Today, Madeira is noted for its un ...

Cask
A barrel or cask is a hollow cylindrical container with a bulging center, longer than it is wide. They are traditionally made of wooden staves and bound by wooden or metal hoops. The word vat is often used for large containers for liquids, usually alcoholic beverages; a small barrel or cask is known as a keg. Modern wooden barrels for wine-making are made of French common oak ('' Quercus robur''), white oak ('' Quercus petraea''), American white oak (''Quercus alba''), more exotic is Mizunara Oak all typically have standard sizes: Recently Oregon Oak ( Quercus Garryana) has been used. *"Bordeaux type" , *"Burgundy type" and *"Cognac type" . Modern barrels and casks can also be made of aluminum, stainless steel, and different types of plastic, such as HDPE. Someone who makes barrels is called a "barrel maker" or cooper (coopers also make buckets, vats, tubs, butter churns, hogsheads, firkins, kegs, kilderkins, tierces, rundlets, puncheons, pipes, tuns, butts, ...

Sherry
Sherry ( es, jerez ) is a fortified wine made from white grapes that are grown near the city of Jerez de la Frontera in Andalusia, Spain. Sherry is 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 fro ...

Wine Fault
A wine fault or defect is an unpleasant characteristic of a wine often resulting from poor winemaking practices or storage conditions, and leading to wine spoilage. Many of the compounds that cause wine faults are already naturally present in wine but at insufficient concentrations to be of issue. In fact, depending on perception, these concentrations may impart positive characters to the wine. However, when the concentration of these compounds greatly exceeds the sensory threshold, they replace or obscure the flavors and aromas that the wine should be expressing (or that the winemaker wants the wine to express). Ultimately the quality of the wine is reduced, making it less appealing and sometimes undrinkable.M. Baldy: ''"The University Wine Course", Third Edition, pp. 37-39, 69-80, 134-140. The Wine Appreciation Guild 2009 . There are many causes for the perception in wine faults, including poor hygiene at the winery, excessive or insufficient exposure of the wine to oxygen, exce ...

Dessert Wine
Dessert wines, sometimes called pudding wines in the United Kingdom, are sweet wines typically served with dessert. There is no simple definition of a dessert wine. In the UK, a dessert wine is considered to be any sweet wine drunk with a meal, as opposed to the white fortified wines ( fino and amontillado sherry) drunk before the meal and the red fortified wines (port and madeira) drunk after it. Thus, most fortified wines are regarded as distinct from dessert wines, but some of the less-strong fortified white wines, such as Pedro Ximénez sherry and Muscat de Beaumes-de-Venise, are regarded as honorary dessert wines. In the United States, by contrast, a dessert wine is legally defined as any wine over 14% alcohol by volume, which includes all fortified wines—and is taxed more highly as a result. This dates back to when the US wine industry only made dessert wines by fortification, but such a classification is outdated now that modern yeast and viticulture can produce dry wi ...

Aging (wine)
The aging of wine is potentially able to improve the quality of wine. This distinguishes wine from most other consumable goods. While wine is perishable and capable of deteriorating, complex chemical reactions involving a wine's sugars, acids and phenolic compounds (such as tannins) can alter the aroma, color, mouthfeel and taste of the wine in a way that may be more pleasing to the taster. The ability of a wine to age is influenced by many factors including grape variety, vintage, viticultural practices, wine region and winemaking style. The condition that the wine is kept in after bottling can also influence how well a wine ages and may require significant time and financial investment.R. Jackson ''"Wine Science: Principles and Applications"'' Third Edition, pp. 431–489, 643–671. Academic Press 2008 .R. Boulton, V. Singleton, L. Bisson, R. Kunkee ''Principles and Practices of Winemaking'', pp. 382–424. Springer 1996 New York . The quality of an aged wine varies significant ...
