Winepress
A winepress is a device used to extract juice from crushed grapes during wine making. There are a number of different styles of presses that are used by wine makers but their overall functionality is the same. Each style of press exerts controlled pressure in order to free the juice from the fruit (most often grapes). The pressure must be controlled, especially with grapes, in order to avoid crushing the seeds and releasing a great deal of undesirable tannins into the wine. Wine was being made at least as long ago as 4000 BC; in 2011, a winepress was unearthed in Armenia with red wine dated 6,000 years old. Press types Basket A basket press consists of a large basket filled with the crushed grapes. Pressure is applied through a plate that is forced down onto the fruit. The mechanism to lower the plate is often either a screw or a hydraulic device. The juice flows through openings in the basket. The basket style press was the first type of mechanized press to be developed, and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hurvat Itri
Horvat 'Ethri ( he, חורבת עתרי; alt. spellings: Hurvat Itri, Ethri, Atari), Hebrew for "Ethri ruin", Arabic name: Umm Suweid ("mother of the buckthorns"), is an archaeological site situated in the Judean Lowlands in modern-day Israel. Excavations at the site uncovered the remains of a now partially restored Jewish village of the Second Temple period, wherein are preserved an ancient synagogue, wine presses, cisterns, ritual baths and stone ossuaries, as well as an underground hideout system.בועז זיסו ואמיר גנור,חורבת עתרי - כפר יהודי מתקופת הבית השני בשפלת יהודה, קדמוניות 123(1), 2002, עמ' 18-27 ebrew/ref> The village was violently destroyed during the Bar Kokhba revolt. Location The site sits upon an elevation of above sea level.

Wine Press From 16th Century
Wine is an alcoholic drink typically made from fermented grapes. Yeast consumes the sugar in the grapes and converts it to ethanol and carbon dioxide, releasing heat in the process. Different varieties of grapes and strains of yeasts are major factors in different styles of wine. These differences result from the complex interactions between the biochemical development of the grape, the reactions involved in fermentation, the grape's growing environment (terroir), and the wine production process. Many countries enact legal appellations intended to define styles and qualities of wine. These typically restrict the geographical origin and permitted varieties of grapes, as well as other aspects of wine production. Wines not made from grapes involve fermentation of other crops including rice wine and other fruit wines such as plum, cherry, pomegranate, currant and elderberry. Wine has been produced for thousands of years. The earliest evidence of wine is from the Caucasus regi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flash Release
Flash release (FR) is a technique used in wine pressing. The technique allows for a better extraction of phenolic compounds and wine polysaccharides. The treatment consists of heating the grapes at 95 °C (203 °F) for several minutes with vapour and then submitting them to a strong vacuum A vacuum is a space devoid of matter. The word is derived from the Latin adjective ''vacuus'' for "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often dis .... The technique can be applied to other type of juice extraction.Application of flash-release, a new extraction procedure (juice, pulp, essential oil); Brat P, 2001, Fruitrop (85), pages 11-13, Journée professionnelle Technofruits 2001, 2001-09-05, Montpellier, France.

Grape Stomping
Grape-treading or grape-stomping is part of the method of maceration used in traditional wine-making.Clarke, Oz (2009). ''Oz Clarke's Pocket Wine Guide 2010.'' Sterling Publishing Company, Cheap, BA (2010). ''Mr. Cheap's Guide to Wine.'' Adams Media, Rather than being crushed in a wine press or by another mechanized method, grapes are repeatedly trampled in vats by barefoot participants to release their juices and begin fermentation. Grape-treading was widespread in the history of winemaking, but with the introduction of industrial methods, it now survives mostly as a recreational or competitive activity at cultural festivals. History One of the earliest extant visual representations of the practice appears on a Roman Empire sarcophagus from the 3rd century AD, which depicts an idealized pastoral scene with a group of Erotes harvesting and stomping grapes at Vindemia, a rural festival.Wight, Karol (2008)Roman sarcophagus, c. 290-300 AD.

History Of The Wine Press
The history of the wine press and of pressing is nearly as old as the history of wine itself with the remains of wine presses providing some of the longest-serving evidence of organised viticulture and winemaking in the ancient world.J. Robinson (ed) ''"The Oxford Companion to Wine"'' Third Edition pp. 545–546 Oxford University Press 2006 The earliest wine press was probably the human foot or hand, crushing and squeezing grapes into a bag or container where the contents would ferment.H. Johnson ''Vintage: The Story of Wine'' pp. 14–31 Simon and Schuster 1989 The pressure applied by these manual means was limited and these early wines were probably pale in colour and body, and eventually ancient winemakers sought out alternative means of pressing their wine. By at least the 18th dynasty, the ancient Egyptians were employing a "sack press" made of cloth that was squeezed with the aid of a giant tourniquet. The use of a wine press in winemaking is mentioned frequently in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rioja Alavesa
Rioja Alavesa ( eu, Arabako Errioxa), officially Cuadrilla de Laguardia-Rioja Alavesa is one of seven ''comarcas'' that make up the province of Álava, Spain. It covers an area of 315.83 km² with a population of 11,360 people (2010). The capital lies at Laguardia. It is part of a notable wine growing region. Geography The Rioja Alavesa's northern boundary is formed by the Sierra de Cantabria and Sierra de Toloño, mountain ranges that separate it from the rest of Álava. To the south, its geographical limit is marked by the Ebro River, its border with the neighboring autonomous community of La Rioja. The Sonsierra of La Rioja includes the municipalities of Ábalos and San Vicente de la Sonsierra, located north of the Ebro River. Although geographically part of the river's left bank, these municipalities form a wedge of land technically belonging to the autonomous community of La Rioja. It thus divides the Rioja Alavesa in two: in the western part, the municipality of Laba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ravensburg
Ravensburg ( Swabian: ''Raveschburg'') is a city in Upper Swabia in Southern Germany, capital of the district of Ravensburg, Baden-Württemberg. Ravensburg was first mentioned in 1088. In the Middle Ages, it was an Imperial Free City and an important trading centre. The "Great Ravensburg Trading Society" (''Große Ravensburger Handelsgesellschaft'') owned shops and trading companies all over Europe. The historic city centre is still very much intact, including three city gates and over 10 towers of the medieval fortification. "The all-white Mehlsack (Flour sack) is a tower marking the Altstadt’s southern edge. A steep staircase leads up to the Veitsburg, a quaint baroque castle." History Ravensburg was first mentioned in writing in 1088. It was founded by the Welfs, a Frankish dynasty in Swabia who became later Dukes of Bavaria and Saxony and who made the castle of Ravensburg their ancestral seat. By a contract of inheritance, in 1191 the Hohenstaufen Frederick Barbarossa acq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phenolic Content In Wine
The phenolic content in wine refers to the phenolic compounds—natural phenol and polyphenols—in wine, which include a large group of several hundred chemical compounds that affect the taste, color and mouthfeel of wine. These compounds include phenolic acids, stilbenoids, flavonols, dihydroflavonols, anthocyanins, flavanol monomers (catechins) and flavanol polymers (proanthocyanidins). This large group of natural phenols can be broadly separated into two categories, flavonoids and non-flavonoids. Flavonoids include the anthocyanins and tannins which contribute to the color and mouthfeel of the wine. The non-flavonoids include the stilbenoids such as resveratrol and phenolic acids such as benzoic, caffeic and cinnamic acids. Origin of the phenolic compounds The natural phenols are not evenly distributed within the fruit. Phenolic acids are largely present in the pulp, anthocyanins and stilbenoids in the skin, and other phenols (catechins, proanthocyanidins and flavonols) in ...

Archimedes' Screw
The Archimedes screw, also known as the Archimedean screw, hydrodynamic screw, water screw or Egyptian screw, is one of the earliest hydraulic machines. Using Archimedes screws as water pumps (Archimedes screw pump (ASP) or screw pump) dates back many centuries. As a machine used for pump, transferring water from a low-lying body of water into irrigation ditches, water is pumped by turning a screw-shaped surface inside a pipe. In the modern world, Archimedes screw pumps are widely used in wastewater treatment plants and for dewatering low-lying regions. Screw turbine, Archimedes Screws Turbines (ASTs) are a new form of small hydroelectric powerplant that can be applied even in low head sites. Screw turbine, Archimedes screw generators operate in a wide range of flows (0.01 m^3/s to 14.5 m^3/s) and heads (0.1 m to 10 m), including low heads and moderate flow rates that is not ideal for traditional turbines and not occupied by high performance technologies.
