Draught Beer
Draught beer, also spelt draft, is beer served from a cask or keg rather than from a bottle or can. Draught beer served from a pressurised keg is also known as Name Until Joseph Bramah patented the beer engine in 1785, beer was served directly from the barrel and carried to the customer. The Old English ' ("carry; pull") developed into a series of related words including ''drag'', ''draw'', and ''draught''. By the time Bramah's beer pumps became popular, the use of the term ''draught'' to refer to the acts of serving or drinking beer was well established and transferred easily to beer served via the hand pumps. In time, the word came to be restricted to only such beer. The usual spelling is now "draught" in the United Kingdom, Ireland, Australia, and New Zealand and more commonly "draft" in North America, although it can be spelt either way. Regardless of spelling, the word is pronounced or depending on the region the speaker is from. Canned draught is beer served from ...

Keg Fonts
A keg is a small barrel. Wooden kegs made by a cooper were used to transport nails, gunpowder, and a variety of liquids. A keg is normally now constructed of stainless steel, although aluminium can be used if it is coated with plastic on the inside. It is commonly used to store, transport, and serve beer. Other alcoholic or non-alcoholic drinks, carbonated or non-carbonated, may be housed in a keg as well. Carbonated drinks are generally kept under pressure in order to maintain carbon dioxide in solution, preventing the beverage from becoming flat. Beer keg Beer kegs are made of stainless steel, or less commonly, of aluminium. A keg has a single opening on one end, called a "bung". A tube called a "spear" extends from the opening to the other end. There is a self-closing valve that is opened by the coupling fitting which is attached when the keg is tapped. There is also an opening at the top of the spear that allows gas (usually carbon dioxide) to drive the beer out of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Watney
James Watney (18 December 1800–16 March 1884) was an English brewer and landowner who resided at Haling Park, Croydon, and Beddington, Surrey. He was born to Daniel Watney (1771–1831) of Mitcham, Surrey and Mary Galpin (1771–1830), daughter of James Galpin (died 1789) of Mitcham, Surrey. He was the grandson of John Watney (1747–1814) and great-grandson of Daniel Watney (1705–1780) of Wimbledon, Surrey who was an ale conner. Professional life The Watney family were the main partners in the Stag Brewery of Pimlico for much of the 19th century. In 1837, James Watney became a partner in the brewery with John Lettsom Elliot and Charles Lambert, as later did his sons James and Norman in 1856. The brewery was known as Elliot, Watney & Co from about 1849. John L Elliot withdrew from the business in 1850, and for 8 years remained a partner in name only. He finally retired in 1858 and the firm became known as James Watney & Co. James Watney then kept the management alm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nitrogen
Nitrogen is the chemical element with the symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element bond to form N2, a colorless and odorless diatomic gas. N2 forms about 78% of Earth's atmosphere, making it the most abundant uncombined element. Nitrogen occurs in all organisms, primarily in amino acids (and thus proteins), in the nucleic acids ( DNA and RNA) and in the energy transfer molecule adenosine triphosphate. The human body contains about 3% nitrogen by mass, the fourth most abundant element in the body after oxygen, carbon, and hydrogen. The nitrogen cycle describes the movement of the element from the air, into the biosphere and organic compounds, then back into the atmosphere. Many indus ...

Carbon Dioxide
Carbon dioxide ( chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.

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 the resulting sweet liquid with 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 and Mesopotamia, brewed beer. Since the nineteenth century the brewing industry has been part of most western economies. The basic ingredients of beer are water and a 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 as adding wheat to aid in retaining the foamy head of the ...

Spile
A spile is a small wooden or metal peg used to control the flow of air into, and carbon dioxide out of, a cask of ale. Spiles can also be used to broach water from trees. Ale use Cask ale is dispensed without the addition of externally supplied gas. That it is served "flat" with no bubbles at all is, however, a misconception. Properly conditioned cask ale will have enough dissolved carbon dioxide to produce bubbles of carbon dioxide. This has been generated by the natural action of the yeast living in the beer while it is stored and transported. In fact, the yeast can produce more carbon dioxide than is required, and it is for this reason that the cask is vented through the hole in the shive. When it is first delivered to the place where beer will be poured from it or where it will be connected to the beer engine, the cask is sealed. It has a keystone (where the tap will be driven in) and a shive (through which it was filled). Once it has been laid down in the location at whi ...

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 ...

Pasteurization
Pasteurization or pasteurisation is a process of food preservation in which packaged and non-packaged foods (such as milk and fruit juices) are treated with mild heat, usually to less than , to eliminate pathogens and extend shelf life. The process is intended to destroy or deactivate microorganisms and enzymes that contribute to food spoilage or risk of disease, including vegetative bacteria, but most bacterial spores survive the process. The process is named after the French microbiologist Louis Pasteur whose research in the 1860s demonstrated that thermal processing would deactivate unwanted microorganisms in wine. Spoilage enzymes are also inactivated during pasteurization. Today, pasteurization is used widely in the dairy industry and other food processing industries to achieve food preservation and food safety. By the year 1999, most liquid products were heat treated in a continuous system where heat can be applied using a plate heat exchanger or the direct ...

Filtration
Filtration is a physical separation process that separates solid matter and fluid from a mixture using a ''filter medium'' that has a complex structure through which only the fluid can pass. Solid particles that cannot pass through the filter medium are described as ''oversize'' and the fluid that passes through is called the ''filtrate''. Oversize particles may form a filter cake on top of the filter and may also block the filter lattice, preventing the fluid phase from crossing the filter, known as ''blinding''. The size of the largest particles that can successfully pass through a filter is called the effective ''pore size'' of that filter. The separation of solid and fluid is imperfect; solids will be contaminated with some fluid and filtrate will contain fine particles (depending on the pore size, filter thickness and biological activity). Filtration occurs both in nature and in engineered systems; there are biological, geological, and industrial forms. Filtration is a ...

Beer Keg Outside The Plasterers Arms, Hoylake
Beer is one of the oldest and the most widely consumed type of alcoholic drink in the world, and the third most popular drink overall after water and tea. It is produced by the brewing and fermentation of starches, mainly derived from cereal grains—most commonly from malted barley, though wheat, maize (corn), rice, and oats are also used. During the brewing process, fermentation of the starch sugars in the wort produces ethanol and carbonation in the resulting beer.Barth, Roger. ''The Chemistry of Beer: The Science in the Suds'', Wiley 2013: . Most modern beer is brewed with hops, which add bitterness and other flavours and act as a natural preservative and stabilizing agent. Other flavouring agents such as gruit, herbs, or fruits may be included or used instead of hops. In commercial brewing, the natural carbonation effect is often removed during processing and replaced with forced carbonation. Some of humanity's earliest known writings refer to the production and di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cask Ale
Real ale is the name coined by the Campaign for Real Ale (CAMRA) for beer that is "brewed from traditional ingredients, matured by secondary fermentation in the container from which it is dispensed, and served without the use of extraneous carbon dioxide". Cask and bottle-conditioned beers Cask and bottle-conditioned beers are referred to as real ale by CAMRA, as both fit its description of beers served from a container in which they have undergone secondary fermentation. Filtered beer The fundamental distinction between real and other ales is that the former are not filtered and the yeast is still present and living in the container from which the real ale is served, although it will have settled to the bottom and is usually not poured into the glass. The natural carbon dioxide is lost during filtration so filtered beer has to be artificially re-carbonated. This can make the beer very 'gassy'. Because the yeast is still present and alive in real ale, a slow process of secon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
