Chill Filtering
Chill filtering is a method in whisky making for removing residue. In chill filtering, whisky is cooled to between and passed through a fine adsorption filter. This is done mostly for cosmetic reasons — to remove cloudiness — however by many whisky drinkers it is thought to impair the taste by removing the details which differentiate between the many distilleries. Method Chill filtering prevents the whisky from becoming hazy when in the bottle, when served, when chilled, or when water or ice is added, as well as precluding sedimentation from occurring in the bottles. It works by reducing the temperature sufficiently so that some fatty acids, proteins and esters (created during the distillation process) precipitate out and are caught on the filter. Whiskies are usually chilled down to . Factors affecting the chill filtering process include the temperature, number of filters used, and speed at which the whisky is passed through the filters. The slower the process and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whisky
Whisky or whiskey is a type of distilled alcoholic beverage made from fermented grain mash. Various grains (which may be malted) are used for different varieties, including barley, corn, rye, and wheat. Whisky is typically aged in wooden casks, which are typically made of charred white oak. Uncharred white oak casks previously used for the aging of sherry are also sometimes used. Whisky is a strictly regulated spirit worldwide with many classes and types. The typical unifying characteristics of the different classes and types are the fermentation of grains, distillation, and aging in wooden barrels. Etymology The word ''whisky'' (or ''whiskey'') is an anglicisation of the Classical Gaelic word (or ) meaning "water" (now written as in Modern Irish, and in Scottish Gaelic). This Gaelic word shares its ultimate origins with Germanic ''water'' and Slavic ''voda'' of the same meaning. Distilled alcohol was known in Latin as ("water of life"). This was translated into Old I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adsorption
Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface. This process creates a film of the ''adsorbate'' on the surface of the ''adsorbent''. This process differs from absorption, in which a fluid (the ''absorbate'') is dissolved by or permeates a liquid or solid (the ''absorbent''). Adsorption is a '' surface phenomenon'', while absorption involves the whole volume of the material, although adsorption does often precede absorption. The term ''sorption'' encompasses both processes, while ''desorption'' is the reverse of it. Like surface tension, adsorption is a consequence of surface energy. In a bulk material, all the bonding requirements (be they ionic, covalent or metallic) of the constituent atoms of the material are fulfilled by other atoms in the material. However, atoms on the surface of the adsorbent are not wholly surrounded by other adsorbent atoms and therefore can attract adsorbates. The exact nature of the bon ...

Fatty Acids
In chemistry, particularly in biochemistry, a fatty acid is a carboxylic acid with an aliphatic chain, which is either saturated or unsaturated. Most naturally occurring fatty acids have an unbranched chain of an even number of carbon atoms, from 4 to 28. Fatty acids are a major component of the lipids (up to 70% by weight) in some species such as microalgae but in some other organisms are not found in their standalone form, but instead exist as three main classes of esters: triglycerides, phospholipids, and cholesteryl esters. In any of these forms, fatty acids are both important dietary sources of fuel for animals and important structural components for cells. History The concept of fatty acid (''acide gras'') was introduced in 1813 by Michel Eugène Chevreul, though he initially used some variant terms: ''graisse acide'' and ''acide huileux'' ("acid fat" and "oily acid"). Types of fatty acids Fatty acids are classified in many ways: by length, by saturation vs unsatura ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proteins
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called peptides. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. The sequence of amino acid residues ...

Esters
In chemistry, an ester is a compound derived from an oxoacid (organic or inorganic) in which at least one hydroxyl group () is replaced by an alkoxy group (), as in the substitution reaction of a carboxylic acid and an alcohol. Glycerides are fatty acid esters of glycerol; they are important in biology, being one of the main classes of lipids and comprising the bulk of animal fats and vegetable oils. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. They perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Phosphoesters form the backbone of DNA molecules. Nitrate esters, such as nitroglycerin, are known for their explosive properties. '' Nomenclature Etymology The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distillery
Distillation, or classical distillation, is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation, usually inside an apparatus known as a still. Dry distillation is the heating of solid materials to produce gaseous products (which may condense into liquids or solids); this may involve chemical changes such as destructive distillation or cracking. Distillation may result in essentially complete separation (resulting in nearly pure components), or it may be a partial separation that increases the concentration of selected components; in either case, the process exploits differences in the relative volatility of the mixture's components. In industrial applications, distillation is a unit operation of practically universal importance, but is a physical separation process, not a chemical reaction. An installation used for distillation, especially of distilled beverages, is a distillery. Distillation includes the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aberlour Distillery
Aberlour is a distillery of Speyside single malt Scotch whisky, in Aberlour, Strathspey, Scotland, at the confluence of the Lour Burn and River Spey near Ben Rinnes. History James Fleming (1830-1895) was born and baptised on the first day of June at Inveravon, the only son of a tenant farmer at Tomfarclas on the Ballindalloch estate. James helped his father on the farm until manhood and then sought a wider and more financially rewarding direction for his future, firstly as a commission agent and dealer in the grain trade. In the mid-1860s he acquired a lease of the Dailuaine distillery at nearby Carron and held it for ten years, making connections in the spirit markets. By the 1871 Census, James had moved to Aberlour, and in 1874 established and developed a new branch agency for the North of Scotland Bank. He became a prominent and respected member of the local community; as an elder of the parish church and in several public positions: chairman of the School Board, county c ...

A'bunadh
A'bunadh is a cask-strength single malt whisky from the Aberlour Distillery in Scotland. Though it has no age statement, it is released in limited run batches, each batch carrying a unique number on its label. Each batch of this whisky is blended from barrels ranging from 5 to 25 years old. A'bunadh is exclusively aged in Spanish oak Oloroso sherry butts and therefore has a sweeter, softer flavour than most scotch. A'bunadh is not chill filtered. The distillery cite the story during distillery tours that when the second pair of stills were put in during 1975, a time capsule was discovered behind the name plate, containing an 1898 newspaper about the distillery fire wrapped around an 1898 bottle of Aberlour. The workmen who discovered the bottle polished off four fifths of the bottle during their lunch break, but the remains of the bottle went off to the laboratories in Keith, Moray, and were analysed. A'bunadh is an attempt to recreate this single malt. The name ''a'buna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kilchoman
Kilchoman ( or ; gd, Cill Chomain ) is a small settlement and large parish on the Scottish island of Islay, within the unitary council of Argyll and Bute. Settlement The settlement of Kilchoman consists of a small number of houses gathered around the 19th century church, a short way above the beach and dunes of Machir Bay, "locally known as Kilchoman Beach or Machrie Beach." The site is ancient, dating back to the early Christianization of the Argyll seaboard. The current-day church was built in 1827 to serve a large community that has since disappeared. It ceased use as a place of worship in 1977. Prior to 1827, a medieval church stood on the location of the now ruined church and before that, an early chapel stood there. The burial ground enclosing the church contains many medieval and renaissance sculptures, and notable high cross, the Kilchoman Cross, dating from the 14th or 15th century. The sculptor of the cross belonged to the Iona School. Close to the settlement ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Springbank Distillery
The Springbank distillery is a family-owned single malt whisky distillery on the Kintyre Peninsula in western Scotland. It is owned by J & A Mitchell & Company, which also owns the Glengyle distillery, the oldest independent bottler, William Cadenheads, and several blended scotch labels. Licensed in 1828, Springbank is one of the last surviving producers of single malt whiskies in Campbeltown, an area that once had over thirty active distilleries. The distillery produces three types of peated and unpeated malt whisky that it bottles under three distinct brands. The majority of its distillate is bottled as a single malt, with a small percentage sold to larger blenders or ending up in one of J&A Mitchell's own blended scotch labels, such as Campbeltown Loch. History Springbank was established by the Reid Brothers in 1828. The Reid Brothers sold the distillery in 1837 to John and William Mitchell. Later, the son of John Mitchell joined the business, which became J&A Mitchell. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scotch Malt Whisky Society
The Scotch Malt Whisky Society (SMWS), founded in Edinburgh in 1983, is a membership organisation which bottles and sells single cask, single malt whisky Single malt whisky is malt whisky from a single distillery. Single malts are typically associated with single malt Scotch, though they are also produced in various other countries. Under the United Kingdom's Scotch Whisky Regulations, a "Si .... It purchases individual casks from more than 170 malt whisky distilleries in Scotland and throughout the world, bottles them and retails directly to its members. It also runs three private members' rooms in the UK and in several international locations. History The origins of the Society lie in Phillip "Pip" Hills' travels around the Scottish Highlands in the late 1970s, during which he sampled several whiskies drawn straight from the cask. Hills was so affected by what he tasted that, in 1978, he persuaded several acquaintances to share in the cost of a cask from the Glenfarcl ...
