Lautering
Lautering () is the beer brewing process that separates the mash into clear liquid wort and residual grain. Lautering usually consists of three steps: mashout, recirculation, and sparging. Mashout Mashout is the term for raising the temperature of the mash to . This stops the enzymatic conversion of starches to fermentable sugars, and makes the mash and wort more fluid. Mashout is considered especially necessary if there is less than 3 liters of water per kilogram of grain (3 pints of water per pound of grain), or if the grain is more than 25% wheat or oats. The mashout step can be done by using external heat, or by adding hot water. Recirculation Recirculation consists of drawing off wort from the bottom of the mash, and adding it to the top. Lauter tuns typically have slotted bottoms to assist in the filtration process. The mash itself functions much as a sand filter to capture mash debris and proteins. This step is monitored by use of a turbidimeter to measure solids in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Mashing
In brewing and distilling, mashing is the process of combining ground grain – malted barley and sometimes supplementary grains such as corn, sorghum, rye, or wheat (known as the " grain bill") – with water and then heating the mixture. Mashing allows the enzymes in the malt (primarily, α-amylase and β-amylase) to break down the starch in the grain into sugars, typically maltose to create a malty liquid called wort. The two main methods of mashing are infusion mashing, in which the grains are heated in one vessel, and decoction mashing, in which a proportion of the grains are boiled and then returned to the mash, raising the temperature. Mashing involves pauses at certain temperatures (notably ) and takes place in a "mash tun" – an insulated brewing vessel with a false bottom. Etymology The term "mashing" probably originates from the Old English noun ''masc'', which means "soft mixture", and the Old English verb ''mæscan,'' which means "to mix with hot water". Us ...

Brewing
Brewing is the production of beer by steeping a starch source (commonly cereal grains, the most popular of which is barley) in water and #Fermenting, fermenting the resulting sweet liquid with Yeast#Beer, yeast. It may be done in a brewery by a commercial brewer, at home by a homebrewer, or communally. Brewing has taken place since around the 6th millennium BC, and archaeological evidence suggests that emerging civilizations, including ancient Egypt, China, and Mesopotamia, brewed beer. Since the nineteenth century the #brewing industry, brewing industry has been part of most western economies. The basic ingredients of beer are water and a Fermentation, fermentable starch source such as malted barley. Most beer is fermented with a brewer's yeast and flavoured with hops. Less widely used starch sources include millet, sorghum and cassava. Secondary sources (adjuncts), such as maize (corn), rice, or sugar, may also be used, sometimes to reduce cost, or to add a feature, such ...

Brewery
A brewery or brewing company is a business that makes and sells beer. The place at which beer is commercially made is either called a brewery or a beerhouse, where distinct sets of brewing equipment are called plant. The commercial brewing of beer has taken place since at least 2500 BC; in ancient Mesopotamia, brewers derived social sanction and divine protection from the goddess Ninkasi. Brewing was initially a cottage industry, with production taking place at home; by the ninth century, monasteries and farms would produce beer on a larger scale, selling the excess; and by the eleventh and twelfth centuries larger, dedicated breweries with eight to ten workers were being built. The diversity of size in breweries is matched by the diversity of processes, degrees of automation, and kinds of beer produced in breweries. A brewery is typically divided into distinct sections, with each section reserved for one part of the brewing process. History Beer may have been known in N ...

Beer
Beer is an alcoholic beverage produced by the brewing and fermentation of starches from cereal grain—most commonly malted barley, although wheat, maize (corn), rice, and oats are also used. The grain is mashed to convert starch in the grain to sugars, which dissolve in water to form wort. Fermentation of the wort by yeast produces ethanol and carbonation in the beer. Beer is one of the oldest and most widely consumed alcoholic drinks in the world, and one of the most popular of all drinks. Most modern beer is brewed with hops, which add bitterness and other flavours and act as a natural preservative and stabilising agent. Other flavouring agents, such as gruit, herbs, or fruits, may be included or used instead of hops. In commercial brewing, natural carbonation is often replaced with forced carbonation. Beer is distributed in bottles and cans, and is commonly available on draught in pubs and bars. The brewing industry is a global business, consisting of several ...

Brasserie Ratz - 20140926 - Cuve à Mélanger
In France, Flanders, and the Francophone world, a brasserie () is a type of French restaurant with a relaxed setting, which serves dishes and other meals. The word ''brasserie'' is French for "brewery" and, by extension, "the brewing business". Although most brasseries still serve a large selection of beers, most of them offer a wider choice of beverages such as wines and liquors. A brasserie can be expected to have professional service, printed menus, and, traditionally, white linen—unlike a bistro which may have none of these. Typically, a brasserie is open every day and serves the same menu, generally composed of a few traditional French dishes, all day. A classic example of a brasserie dish is steak frites. Etymology The term ''brasserie'' is French for "brewery", from Middle French ''brasser'' "to brew", from Old French ''bracier'', from -4; we might wonder whether there's a point at which it's appropriate to talk of the beginnings of French, that is, when it wa ... ...

English Beer
Beer has been brewed in England for thousands of years. As a beer brewing country, it is known for top fermented cask beer (also called real ale) which finishes maturing in the cellar of the pub rather than at the brewery and is served with only natural carbonation. English beer styles include bitter, mild, brown ale and old ale. Stout, porter and India pale ale were also originally brewed in London. Lager increased in popularity from the mid-20th century. Other modern developments include the consolidation of large brewers into multinational corporations; the growth of beer consumerism; and the expansion of microbreweries and bottle-conditioned beers. History Romano-Celtic Britain Brewing in what is now England was probably well established when the Romans arrived in 54 BC, and certainly continued under them. In the 1980s, archaeologists found the evidence that Rome's soldiers in Britain sustained themselves on Celtic ale. A series of domestic and military accou ...

Brewpub
Craft beer is beer manufactured by craft breweries, which typically produce smaller amounts of beer than larger "macro" breweries and are often independently owned. Such breweries are generally perceived and marketed as emphasising enthusiasm, new flavours, and varied brewing techniques. The microbrewery movement began in both the United States and United Kingdom in the 1970s, although traditional artisanal brewing existed in Europe for centuries and subsequently spread to other countries. As the movement grew, and some breweries expanded their production and distribution, the more encompassing concept of craft brewing emerged. A brewpub is a pub that brews its own beer for sale on the premises. Producer definitions Microbrewery Although the term "microbrewery" was originally used in relation to the size of breweries, it gradually came to reflect an alternative attitude and approach to brewing flexibility, adaptability, experimentation and customer service.

Wedge Wire
A wedge is a triangular shaped tool, a portable inclined plane, and one of the six simple machines. It can be used to separate two objects or portions of an object, lift up an object, or hold an object in place. It functions by converting a force applied to its blunt end into forces perpendicular ( normal) to its inclined surfaces. The mechanical advantage of a wedge is given by the ratio of the length of its slope to its width..''McGraw-Hill Concise Encyclopedia of Science & Technology'', Third Ed., Sybil P. Parker, ed., McGraw-Hill, Inc., 1992, p. 2041. Although a short wedge with a wide angle may do a job faster, it requires more force than a long wedge with a narrow angle. The force is applied on a flat, broad surface. This energy is transported to the pointy, sharp end of the wedge, hence the force is transported. The wedge simply transports energy in the form of friction and collects it to the pointy end, consequently breaking the item. History Wedges have existed fo ...

German Beer
Beer (, ) is a major part of German culture. According the Reinheitsgebot (German beer purity law), only water, hops, yeast and malt are permitted as ingredients in its production. Beers not exclusively using barley-malt, such as wheat beer, must be top-fermented. In 2023, Germany ranked fourth in beer exports and in 2020, Germany ranked third in Europe in terms of per-capita beer consumption, trailing behind the Czech Republic and Austria. Styles Pale lagers *Pilsener is a pale lager with a light body and a more prominent hop character, is the most popular style, holding around two-thirds of the market. It has an alcohol content of 4.5–5% ABV and 11–12° Plato. * Märzen is a medium-bodied, malty lager that comes in pale, amber, and dark varieties. 13–14° Plato, 5.2–6% ABV. This type of beer is traditionally served at the Munich Oktoberfest. *Export is a pale lager brewed around Dortmund, and is fuller, maltier, and less hoppy than Pilsner. 12–12.5° Plato, 5 ...

Low-alcohol Beer
Low-alcohol beer is beer with little or no alcohol by volume that aims to reproduce the taste of beer while eliminating or reducing the inebriating effect, carbohydrates, and calories of regular alcoholic brews. Low-alcohol beers can come in different beer styles such as lagers, Stout, stouts, and ales. Low-alcohol beer is also known as light beer, non-alcoholic beer, small beer, small ale, or near-beer. History Low-alcohol brews such as small beer date back at least to Middle Ages, medieval Europe, where they served as a less risky alternative to water (which often was polluted by faeces and parasites) and were less expensive than higher-quality, higher-alcohol brews like stouts, porters, and ales. More recently, the temperance movements and the need to avoid alcohol (drug), alcohol while driving, operating machinery, taking certain medications, etc. led to the development of non-intoxicating beers. In the United States, according to John Naleszkiewicz, non-alcoholic brews were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Nephelometer
A nephelometer or aerosol photometer is an instrument for measuring the concentration of suspended particulates in a liquid or gas colloid. A nephelometer measures suspended particulates by employing a light beam (source beam) and a light detector set to one side (often 90°) of the source beam. Particle density is then a function of the light reflected into the detector from the particles. To some extent, how much light reflects for a given density of particles is dependent upon properties of the particles such as their shape, color, and reflectivity. Nephelometers are calibrated to a known particulate, then use environmental factors (k-factors) to compensate lighter or darker colored dusts accordingly. K-factor is determined by the user by running the nephelometer next to an air sampling pump and comparing results. There are a wide variety of research-grade nephelometers on the market as well as open source varieties. Nephelometer uses The main uses of nephelometers relat ...
