Flor
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 resultin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one Cell (biology), biological cell. They constitute a large domain (biology), domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, Hot spring, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the nitrogen fixation, fixation of nitrogen from the Earth's atmosphere, atmosphere. The nutrient cycle includes the decomposition of cadaver, dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulp ...

Fino
Fino ("refined" in Spanish) is the driest and palest of the traditional varieties of sherry and Montilla-Moriles fortified wine. They are consumed comparatively young and, unlike the sweeter varieties, should be consumed soon after the bottle is opened as exposure to air can cause them to lose their flavour within hours. Flor The defining component of Fino sherries is the strain of yeast known as flor that floats in a layer on top of sherry in the wine barrel. Until the mid-19th century most sherry winemakers did not understand what this yellowish foam that randomly appeared in some of their barrels was. They would mark these barrels as "sick" and relegate them to their lowest bottlings of wine. It turned out that this strain of ''Saccharomyces'' yeast thrived in air, and the more "head room" there was in the barrel the more likely it was to develop. Over time winemakers noticed that these wines were lighter and fresher than their other sherries, with the flor acting as a p ...

Andalucía
Andalusia (, ; es, Andalucía ) is the southernmost autonomous community in Peninsular Spain. It is the most populous and the second-largest autonomous community in the country. It is officially recognised as a "historical nationality". The territory is divided into eight provinces: Almería, Cádiz, Córdoba, Granada, Huelva, Jaén, Málaga, and Seville. Its capital city is Seville. The seat of the High Court of Justice of Andalusia is located in the city of Granada. Andalusia is located in the south of the Iberian Peninsula, in southwestern Europe, immediately south of the autonomous communities of Extremadura and Castilla-La Mancha; west of the autonomous community of Murcia and the Mediterranean Sea; east of Portugal and the Atlantic Ocean; and north of the Mediterranean Sea and the Strait of Gibraltar. Andalusia is the only European region with both Mediterranean and Atlantic coastlines. The small British Overseas Territory of Gibraltar shares a land border ...

Yeast
Yeasts are eukaryotic, single-celled microorganisms classified as members of the fungus kingdom. The first yeast originated hundreds of millions of years ago, and at least 1,500 species are currently recognized. They are estimated to constitute 1% of all described fungal species. Yeasts are unicellular organisms that evolved from multicellular ancestors, with some species having the ability to develop multicellular characteristics by forming strings of connected budding cells known as pseudohyphae or false hyphae. Yeast sizes vary greatly, depending on species and environment, typically measuring 3–4 µm in diameter, although some yeasts can grow to 40 µm in size. Most yeasts reproduce asexually by mitosis, and many do so by the asymmetric division process known as budding. With their single-celled growth habit, yeasts can be contrasted with molds, which grow hyphae. Fungal species that can take both forms (depending on temperature or other conditions) a ...

Vin Jaune
''Vin jaune'' ( French for "yellow wine") is a special and characteristic type of white wine made in the 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, known as the ''voile'', on the wine's surface. ''Vin jaune'' shares many similarities with Sherry, including some 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 grape varieties using cultured yeast such as the ''vin de voile'' wine produced in the Gaillac.J. Robinson (ed), ''"The Oxford Companion to Wine"'', Third Edition, p. 750, Oxford University Press 2006, Production Vin jaune is made from late harvest Savagnin grapes, a white variety in the Tr ...

Amontillado
Amontillado () is a variety of sherry wine characterised by being darker than fino but lighter than oloroso. It is named after the Montilla region of Spain, where the style originated in the 18th century, although the name "Amontillado" is sometimes used commercially as a simple measure of colour to label any sherry lying between a fino and an oloroso. It features prominently in the Edgar Allan Poe short story "The Cask of Amontillado". An Amontillado sherry begins as a fino, fortified to approximately 15.5% alcohol with a cap of flor yeast limiting its exposure to the air. A cask of fino is considered to be amontillado if the layer of flor fails to develop adequately, is intentionally killed by additional fortification, or is allowed to die off through non-replenishment. Without the layer of flor, amontillado must be fortified to approximately 17.5% alcohol so that it does not oxidise too quickly. After the additional fortification, Amontillado oxidises slowly, exposed to oxy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manzanilla (wine)
Manzanilla is a fortified wine similar to fino sherry made in the port of Sanlúcar de Barrameda, in the province of Cádiz, Andalusia (Spain), and is produced under the Spanish Denominación de Origen Protegida (DOP) of Manzanilla-Sanlúcar de Barrameda DOP. In Spanish, chamomile infusion is called "manzanilla", and thus this wine gets the name because the wine's aroma is said to be reminiscent of such infusion. Manzanilla is manufactured using the same methods as a fino sherry and results in a very pale, dry wine. It is often described as having a savoury and salty flavour, believed to develop from the chalky soil near the sea estuary of the Guadalquivir river. Sanlúcar de Barrameda's cool temperatures and high humidity contribute to a higher yield of flor yeast than in Jerez or El Puerto de Santa María. The thicker cap of flor better protects the wine from contact with the air, resulting in a fresher, more delicate flavour than a fino from Jerez. It is typically aged f ...

Oloroso
Oloroso ("scented" in Spanish) is a variety of fortified wine (sherry) made in Jerez and Montilla-Moriles and produced by oxidative aging. It is normally darker than Amontillado. Oloroso is usually dark and nutty. Unlike the fino and Amontillado sherries, in oloroso the flor yeast is suppressed by fortification at an earlier stage. This causes the finished wine to lack the fresh yeasty taste of the fino sherries. Without the layer of flor, the sherry is exposed to air through the slightly porous walls of the American or Canadian oak casks and undergoes oxidative aging. As the wine ages, it becomes darker and stronger and is often left for many decades. Oloroso sherry is also the base for many of the sweet sherries developed for the international market, such as Bristol Cream, in which oloroso is sweetened and sometimes has the color removed by charcoal filtering to achieve the desired effect.

Gose
Gose () is a warm fermented beer that originated in Goslar, Germany. It is usually brewed with at least 50% of the grain bill being malted wheat. Dominant flavours in gose include a lemon sourness, a herbal characteristic, and a strong saltiness (the result of either local water sources or added salt). Gose beers typically do not have prominent hop bitterness, flavours, or aroma. The beers typically have a moderate alcohol content of 4 to 5% ABV. Because of the use of coriander and salt, gose does not comply with the traditional ingredient regulations in German-speaking countries, but it is allowed an exemption on the grounds of being a regional specialty. It acquires its characteristic sourness through inoculation with ''Lactobacillus'' bacteria.Gose Häppchen: 100 Jahre Gosenschenke Ohne Bedenken, 1999, Leipzig, pages 13 - 63. Gose belongs to the same family of sour wheat beers which were once brewed across Northern Germany and the Low Countries. Other beers of this famil ...

Fermentation (wine)
The process of fermentation in winemaking turns grape juice into an alcoholic beverage. During fermentation, yeasts transform sugars present in the juice into ethanol and carbon dioxide (as a by-product). In winemaking, the temperature and speed of fermentation are important considerations as well as the levels of oxygen present in the must at the start of the fermentation. The risk of stuck fermentation and the development of several wine faults can also occur during this stage, which can last anywhere from 5 to 14 days for ''primary fermentation'' and potentially another 5 to 10 days for a '' secondary fermentation''. Fermentation may be done in stainless steel tanks, which is common with many white wines like Riesling, in an open wooden vat, inside a wine barrel and inside the wine bottle itself as in the production of many sparkling wines. History The natural occurrence of fermentation means it was probably first observed long ago by humans.H. Johnson: ''Vintage: The Sto ...
