Malting is a process applied to cereal grains, in which the grains are made to germinate and then are quickly dried before the plant develops. Germination is the process whereby growth emerges from a period of dormancy [1]
The term malt refers to several products of the process:
Malted grain is used to make beer, whisky, and malt vinegar. Beer is the world's oldest and most widely consumed Alcoholic beverage and the third most popular drink overall after water and tea Whisky (uisge-beatha or whiskey (uisce beatha or fuisce) refers to a broad category of Alcoholic beverages that are distilled from fermented Vinegar is an acidic liquid processed from the Fermentation of Ethanol in a process that yields its key ingredient Acetic acid (also called ethanoic acid Malting grains develops the enzymes that are required to modify the grain's starches into sugars, including monosaccharides (glucose, fructose, etc. Enzymes are Biomolecules that catalyze ( ie increase the rates of Chemical reactions Almost all enzymes are Proteins Starch, CAS # 9005-25-8 Chemical formula (C6H10O5n is a Polysaccharide Monosaccharides (from Greek monos: single sacchar: sugar are the most basic unit of Carbohydrates They consist of one sugar and Glucose (Glc a Monosaccharide (or simple Sugar) also known as grape sugar, is an important Carbohydrate in Biology. Fructose (also levulose or laevulose) is a simple reducing Sugar ( Monosaccharide) found in many foods and is one of the three ) and disaccharides (sucrose, etc. A disaccharide is a Sugar (a Carbohydrate) composed of two Monosaccharides 'Disaccharide' is one of the four chemical groupings of carbohydrates ( Solubility of Pure SucroseTemperature(Cg ). It also develops other enzymes, such as proteases which break down the proteins in the grain into forms which can be utilized by yeast. Barley is the most commonly malted grain in part because of its high diastatic power or enzyme content. Barley ( Hordeum vulgare) is an annual Cereal Grain, which serves as a major animal Feed crop, with smaller amounts used for The diastatic power (DP also called the "diastatic activity" or "enzymatic power" of a grain generally refers only to Malts grains which have begun to Germinate Enzymes are Biomolecules that catalyze ( ie increase the rates of Chemical reactions Almost all enzymes are Proteins Also very important is the retention of the grain's husk even after threshing, unlike the bare seeds of threshed wheat or rye. Husk (or hull) in botany is the outer shell or coating of a seed This protects the growing acrospire (developing plant embryo) from damage during malting, which can easily lead to mold growth. An embryo (from Greek:, plural, lit "that which grows" from en- "in" + bryein "to swell be full" is a multicellular It also allows the mash of converted grain to create a filter bed during sparging (see brewing). Brewing is the production of Alcoholic beverage and Alcohol fuel through fermentation. Other grains may be malted, although the resulting malt may not have sufficient enzymatic content to convert its own starch content fully and efficiently and may create a "stuck sparge" . Starch, CAS # 9005-25-8 Chemical formula (C6H10O5n is a Polysaccharide
A malting, sometimes called maltings, malthouse, or malting floor, is a building that houses the process of converting barley into malt, for use in the brewing or distilling process. Barley ( Hordeum vulgare) is an annual Cereal Grain, which serves as a major animal Feed crop, with smaller amounts used for Brewing is the production of Alcoholic beverage and Alcohol fuel through fermentation. Distillation is a method of separating Mixtures based on differences in their volatilities in a boiling liquid mixture A typical floor maltings is a long, single-story building with a floor that slopes slightly from one end of the building to the other. There are a number of maltings buildings still in existence, and a handful are still operational. Floor maltings began to be phased out from the 1940's in favour of 'pneumatic plants'. Here large industrial fans are used to blow air through the germinating grain beds and to pass hot air through the malt being kilned. Kilns are thermally insulated chambers or Ovens in which controlled temperature regimes are produced Like floor maltings these pneumatic plants are batch processes but of considerably greater size, typically 100 tonne batches compared with 20 tonne batches for a floor maltings.
