Flor Núñez
Flor (Spanish and Portuguese for ''flower'') in winemaking, is a film of yeast on the surface of wine, important in the manufacture of some styles of sherry. The flor is formed naturally under certain winemaking conditions, from indigenous yeasts found in the region of Andalucía in southern Spain. Normally in winemaking, it is essential to keep young wines away from exposure to air by sealing them in airtight barrels, to avoid contamination by bacteria and yeasts that tend to spoil it. However, in the manufacture of sherries, the slightly porous oak barrels are deliberately filled only about five-sixths full with the young wine, leaving "the space of two fists" empty to allow the flor yeast to take form and the bung is not completely sealed. The flor favors cooler climates and higher humidity, so the sherries produced in the coastal Sanlúcar de Barrameda and El Puerto de Santa María have a thicker cap of flor than those produced inland in Jerez. The yeast gives the resulting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anaerobic Organism
An anaerobic organism or anaerobe is any organism that does not require oxygen, molecular oxygen for growth. It may react negatively or even die if free oxygen is present. In contrast, an aerobic organism (aerobe) is an organism that requires an oxygenated environment. Anaerobes may be unicellular (e.g. protozoans, bacteria) or multicellular. Most fungi are obligate aerobes, requiring oxygen to survive. However, some species, such as the Chytridiomycota that reside in the rumen of cattle, are obligate anaerobes; for these species, anaerobic respiration is used because oxygen will disrupt their metabolism or kill them. The sea floor is possibly one of the largest accumulation of anaerobic organisms on Earth, where microbes are primarily concentrated around Hydrothermal_vent, hydrothermal vents. These microbes produce energy in absence of sunlight or oxygen through a process called chemosynthesis, whereby inorganic compounds such as hydrogen gas, hydrogen sulfide or ferrous ions are ...

Tokaj
Tokaj () is a historical town in Borsod-Abaúj-Zemplén county, Northern Hungary, 54 kilometers from county capital Miskolc. It is the centre of the Tokaj-Hegyalja wine district where Tokaji wine is produced. History The wine-growing area was first mentioned by the name Tokaj in 1067. The town itself was first mentioned in documents in 1353. Its first castle was a motte, which was destroyed during the Mongol invasion of Hungary. By the 14th century, the town already had a stone castle, belonging to the Diósgyőr estate. After 1450, Tokaj was the property of the Hunyadi family, so after Matthias Hunyadi became king, the town became a royal estate. In 1526, after the Ottomans captured Petervarad (modern day Petrovaradin, Serbia), Cistercians from Petervarad and its surroundings relocated to Tokaj and greatly improved wine making in the area. In 1705, Francis II Rákóczi ordered the castle to be destroyed. After the Austro-Hungarian Compromise of 1867, the town prosp ...

Veil
A veil is an article of clothing or hanging cloth that is intended to cover some part of the human head, head or face, or an object of some significance. Veiling has a long history in European, Asian, and African societies. The practice has been prominent in different forms in Judaism, Christianity, and Islam. The practice of veiling is especially associated with women and sacred objects, though in some cultures, it is men, rather than women, who are expected to wear a veil. Besides its enduring religious significance, veiling continues to play a role in some modern secular contexts, such as wedding customs. History Antiquity Elite women in ancient Mesopotamia and in the Rise of Macedon, Macedonian and Persian Empire, Persian empires wore the veil as a sign of respectability and high status. The earliest attested reference to veiling is found a Middle Assyrian Empire, Middle Assyrian law code dating from between 1400 and 1100 BC. Assyria had explicit sumptuary laws detailin ...

Jura Wine
Jura wine is French wine produced in the Jura '' département''. Located between Burgundy and Switzerland, this cool climate wine region produces wines with some similarity to Burgundy and Swiss wine. Jura wines are distinctive and unusual wines, the most famous being '' vin jaune'', which is made by a similar process to Sherry, developing under a flor-like strain of yeast. This is made from the local Savagnin grape variety. Other grape varieties include Poulsard, Trousseau, and Chardonnay. Other wine styles found in Jura includes a '' vin de paille'' made from Chardonnay, Poulsard and Savagnin, a sparkling '' Crémant du Jura'' made from slightly unripe Chardonnay grapes, and a '' vin de liqueur'' known as ''Macvin du Jura'' made by adding marc to halt fermentation. The renowned French chemist and biologist Louis Pasteur was born and raised in the Jura region and owned a vineyard near Arbois. Climate and geography The climate of Jura is continental with many similariti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vin Jaune
is a special and characteristic type of white wine made in the Jura (wine), Jura region in eastern France. It is similar to dry fino Sherry and gets its character from being matured in a barrel under a film of yeast (wine), yeast, known as the ''voile'', on the wine's surface. ''Vin jaune'' shares many similarities with Sherry, including some aromas (wine), aromas, but unlike Sherry, it is not a fortified wine. The wine is made from the Savagnin grape, with some of the most premium examples coming from the marl based vineyards in the Château-Chalon AOC. In other French wine regions, there has been experimentation in producing similar style wines from Chardonnay and other local List of grape varieties, grape varieties using cultured yeast such as the ''vin de voile'' wine produced in the Gaillac.J.

Vinegar
Vinegar () is an aqueous solution of diluted acetic acid and trace compounds that may include flavorings. Vinegar typically contains from 5% to 18% acetic acid by volume. Usually, the acetic acid is produced by a double fermentation, converting simple sugars to ethanol using yeast and ethanol to acetic acid using acetic acid bacteria. Many types of vinegar are made, depending on source materials. The product is now mainly used in the culinary arts as a flavorful, acidic cooking ingredient or in pickling. Various types are used as condiments or garnishes, including balsamic vinegar and malt vinegar. As the most easily manufactured mild acid, it has a wide variety of industrial and domestic uses, including functioning as a household cleaner. Etymology The word "vinegar" arrived in Middle English from Old French (''vyn egre''; sour wine), which in turn derives from Latin: (wine) + (neuter gender of , sour). Vinegar was formerly also called . The word "acetic" derives from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxidize
Redox ( , , reduction–oxidation or oxidation–reduction) is a type of chemical reaction in which the oxidation states of the reactants change. Oxidation is the loss of electrons or an increase in the oxidation state, while reduction is the gain of electrons or a decrease in the oxidation state. The oxidation and reduction processes occur simultaneously in the chemical reaction. There are two classes of redox reactions: * Electron-transfer – Only one (usually) electron flows from the atom, ion, or molecule being oxidized to the atom, ion, or molecule that is reduced. 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 oxidatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acetaldehyde
Acetaldehyde (IUPAC systematic name ethanal) is an organic compound, organic chemical compound with the chemical formula, formula , sometimes abbreviated as . It is a colorless liquid or gas, boiling near room temperature. It is one of the most important aldehydes, occurring widely in nature and being produced on a large scale in industry. Acetaldehyde occurs naturally in coffee, bread, and ripe fruit, and is produced by plants. It is also produced by the partial oxidation of ethanol by the liver enzyme alcohol dehydrogenase and is a contributing cause of hangover after alcohol (drug), alcohol consumption. Pathways of exposure include air, water, land, or groundwater, as well as drink and smoke. Consumption of disulfiram inhibits acetaldehyde dehydrogenase, the enzyme responsible for the metabolism of acetaldehyde, thereby causing it to build up in the body.
