Sour Mash
Sour mash (or sourmash) is a process used in the distilling industry that uses material from an older batch of mash to adjust the acidity of a new mash. The term can also be used as the name of the type of mash used in such a process, and a bourbon made using this process can be referred to as a ''sour mash bourbon''. Sour beer may also be created with this process. Well-known brands of sour mash whiskey are Jim Beam and Jack Daniel's. Process In the sour mash process, the mash – a mixture of grain, malt and water – is conditioned with some amount of spent mash (previously fermented mash that still contains dead yeast, a good food source for live yeast). Spent mash is also known as spent beer, distillers' spent grain, and slop or feed mash because it is also used as animal feed. The acid introduced by the sour mash controls the growth of bacteria that could taint the Bourbon. An established and active strain of live yeast is introduced into the mash to be f ...

Food Spoilage
Food spoilage is the process whereby food becomes unsuitable to ingest by a person; it is a matter of food safety. Bacteria and various fungi are the causes of spoilage, and can create serious consequences for consumers, but there are preventive measures that can be taken. The precise cause of the process is due to many outside factors as a side-effect of the type of product it is, as well as how the product is packaged and stored. Food spoilage is the reason for food preservation, to extend shelf life. Processed meat, Meat is processed, Frozen food, food is frozen, and Canning, food is canned. Due to spoilage, one-third of the world's food produced for human consumption is lost every year. Bacteria Some bacteria are responsible for the spoilage of food. When bacteria breaks down the food, acids and other waste products are generated in the process. While the bacteria itself may or may not be harmful, the waste products may be unpleasant to taste or may even be harmful to one's ...

Dunder
Dunder is the liquid left in a boiler after distilling a batch of rum. It is a traditional flavor source used in the fermentation of the wash of Jamaican rum. Similar in process to sour mash in Bourbon whiskey Bourbon whiskey (; also simply bourbon) is a Aging (food), barrel-aged American whiskey made primarily from corn (maize). The name derives from the Kingdom of France, French House of Bourbon, although the precise source of inspiration is uncerta ..., it is a crucial step in achieving an authentic rum flavor. In Europe, waste liquors from alcohol distillation are referred to as vinasse. Dunder contains many by-products that help in future fermentations, including dead yeast cells, which are an excellent yeast nutrient. Subsequent fermentations using dunder must be carefully controlled to prevent stress on the yeast which will cause a greater amount of mutations. Also if planning to store dunder before use it is advised to refrigerate the dunder to suppress cell division ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barm
Barm, also called ale yeast, is the foam or scum formed on the top of a fermenting liquid, such as beer, wine, or feedstock for spirits or industrial ethanol distillation. It is used to leaven bread, or set up fermentation in a new batch of liquor. Barm, as a leaven, has also been made from ground millet combined with must out of wine-tubs and is sometimes used in English baking as a synonym for a natural leaven (sourdough). Reinhart derived the term from his training undeMonica Spiller Various cultures derived from barm, usually ''Saccharomyces cerevisiae'', became ancestral to most forms of brewer's yeast and baker's yeast currently on the market. A barm cake is a soft, round, flattish bread roll from North West England, traditionally leavened with barm. In Ireland, barm is used in the traditional production of barmbrack, a fruited bread. Emptins, a homemade product similar to barm and usually made from hops Hops are the flowers (also called seed cones or strobiles) ...

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] |
Lactic Acid Bacteria
Lactobacillales are an order of gram-positive, low-GC, acid-tolerant, generally nonsporulating, nonrespiring, either rod-shaped (bacilli) or spherical ( cocci) bacteria that share common metabolic and physiological characteristics. These bacteria, usually found in decomposing plants and milk products, produce lactic acid as the major metabolic end product of carbohydrate fermentation, giving them the common name lactic acid bacteria (LAB). Production of lactic acid has linked LAB with food fermentations, as acidification inhibits the growth of spoilage agents. Proteinaceous bacteriocins are produced by several LAB strains and provide an additional hurdle for spoilage and pathogenic microorganisms. Furthermore, lactic acid and other metabolic products contribute to the organoleptic and textural profile of a food item. The industrial importance of the LAB is further evidenced by their generally recognized as safe (GRAS) status, due to their ubiquitous appearance in food and the ...

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 ...

Liquor
Liquor ( , sometimes hard liquor), spirits, distilled spirits, or spiritous liquor are alcoholic drinks produced by the distillation of grains, fruits, vegetables, or sugar that have already gone through ethanol fermentation, alcoholic fermentation. While the word ''liquor'' ordinarily refers to distilled alcoholic spirits rather than drinks produced by fermentation alone, it can sometimes be used more broadly to refer to any alcoholic beverage (or even non-alcoholic ones produced by distillation or some other practices, such as the brewed liquor of a tea). The distillation process concentrates the alcohol, the resulting condensate has an increased alcohol by volume. As liquors contain significantly more alcohol (drug), alcohol (ethanol) than other alcoholic drinks, they are considered "harder". In North America, the term ''hard liquor'' is sometimes used to distinguish distilled alcoholic drinks from non-distilled ones, whereas the term ''spirits'' is more commonly used in ...

Strain (biology)
In biology, a strain is a genetic variant, a subtype or a culture within a biological species. Strains are often seen as inherently artificial concepts, characterized by a specific intent for genetic isolation. This is most easily observed in microbiology where strains are derived from a single cell colony and are typically quarantined by the physical constraints of a Petri dish. Strains are also commonly referred to within virology, botany, and with rodents used in experimental studies. Microbiology and virology It has been said that "there is no universally accepted definition for the terms 'strain', ' variant', and 'isolate' in the virology community, and most virologists simply copy the usage of terms from others". A strain is a genetic variant or subtype of a microorganism such as a bacterial strain or a specific strain of a virus, or fungus. For example, a "flu strain" is a certain biological form of the influenza or "flu" virus. These flu strains are characterized ...

Brewer's Spent Grain
Brewer's spent grain (BSG) or draff is a food waste that is a byproduct of the brewing industry that makes up 85 percent of brewing waste. BSG is obtained as a mostly solid residue after wort production in the brewing process. The product is initially wet, with a short shelf-life, but can be dried and processed in various ways to preserve it. Because spent grain is widely available wherever beer is consumed and is frequently available at a low cost, many potential uses for this waste have been suggested and studied as a means of reducing its environmental impact, such as use as a food additive, animal feed, fertilizer or paper. Composition The majority of BSG is composed of barley malt grain husks in combination with parts of the pericarp and seed coat layers of the barley. Though the composition of BSG can vary, depending on the type of barley used, the way it was grown, and other factors, BSG is usually rich in cellulose, hemicelluloses, lignin, and protein. BSG is also n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distillation
Distillation, also classical distillation, is the process of separating the component substances of a liquid mixture of two or more chemically discrete substances; the separation process is realized by way of the selective boiling of the mixture and the condensation of the vapors in a still. Distillation can operate over a wide range of pressures from 0.14 bar (e.g., ethylbenzene/ styrene) to nearly 21 bar (e.g., propylene/propane) and is capable of separating feeds with high volumetric flowrates and various components that cover a range of relative volatilities from only 1.17 ( o-xylene/ m-xylene) to 81.2 (water/ ethylene glycol). Distillation provides a convenient and time-tested solution to separate a diversity of chemicals in a continuous manner with high purity. However, distillation has an enormous environmental footprint, resulting in the consumption of approximately 25% of all industrial energy use. The key issue is that distillation operates based on phase changes, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malt
Malt is any cereal grain that has been made to germinate by soaking in water and then stopped from germinating further by drying with hot air, a process known as "malting". Malted grain is used to make beer, whisky, malted milk, malt vinegar, confections such as Maltesers and Whoppers, flavored drinks such as Horlicks, Ovaltine, and Milo (drink), Milo, and some baked goods, such as malt loaf, bagels, and Rich Tea biscuits. Malted grain that has been ground into a coarse meal is known as "sweet meal". Malting grain develops the enzymes (α-amylase, β-amylase) required for modifying the grains' starches into various types of sugar, including monosaccharide glucose, disaccharide maltose, trisaccharide maltotriose, and higher sugars called maltodextrines. It also develops other enzymes, such as proteases, that break down the proteins in the grain into forms that can be used by yeast. The point at which the malting process is stopped affects the starch-to-enzyme ratio, and partly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
