Alcohol Congener Analysis
Alcohol congener analysis of blood and urine is used to provide an indication of the type of alcoholic beverage consumed. The analysis involves investigating compounds called congeners that give the beverage a distinctive appearance, aroma, and flavour, not including water and ethanol. The theory of discovering one's drinking habits has been investigated since the late 1970s, predominantly in Germany, for "hip-flask" defence cases (after-drinking). Alcohol congener analysis can play a crucial role in these cases where the driver is apprehended some time after a motor vehicle incident who, when returning a positive alcohol reading then claim that this is due to drinking an alcoholic beverage only after the incident. This traditional methodology for congener analysis has focused solely on the detection of fermentation by-product congeners that are found in all alcoholic beverages. By comparing the ratios of a set standard of congeners, the ingested alcoholic beverage type is propose ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alcoholic Beverage
An alcoholic beverage (also called an alcoholic drink, adult beverage, or a drink) is a drink that contains ethanol, a type of alcohol that acts as a drug and is produced by fermentation of grains, fruits, or other sources of sugar. The consumption of alcoholic drinks, often referred to as "drinking", plays an important social role in many cultures. Most countries have laws regulating the production, sale, and consumption of alcoholic beverages. Regulations may require the labeling of the percentage alcohol content (as ABV or proof) and the use of a warning label. Some countries ban such activities entirely, but alcoholic drinks are legal in most parts of the world. The global alcoholic drink industry exceeded $1 trillion in 2018. Alcohol is a depressant, which in low doses causes euphoria, reduces anxiety, and increases sociability. In higher doses, it causes drunkenness, stupor, unconsciousness, or death. Long-term use can lead to an alcohol use disorder, an incre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Congener (alcohol)
In the alcoholic beverages industry, congeners are substances, other than the desired type of alcohol, ethanol, produced during fermentation. These substances include small amounts of chemicals such as methanol and other alcohols (known as fusel alcohols), acetone, acetaldehyde, esters, tannins, and aldehydes (e.g. furfural). Congeners are responsible for most of the taste and aroma of distilled alcoholic beverages, and contribute to the taste of non-distilled drinks. It has been suggested that these substances contribute to the symptoms of a hangover. Brandy, rum and red wine have the highest amount of congeners, while vodka and beer have the least. Congeners are the basis of alcohol congener analysis, a sub-discipline of forensic toxicology which determines what a person drank. There is some evidence that high-congener drinks induce more severe hangovers, but the effect is not well studied and is still secondary to the total amount of ethanol consumed.

Hip Flask Defence
In places like the United Kingdom, a hip flask defence is a defence to an allegation of drink driving that a driver had consumed alcohol between the time of a vehicular offence, such as a traffic collision, and a breathalyser test A breathalyzer or breathalyser (a portmanteau of ''breath'' and ''analyzer/analyser'') is a device for estimating blood alcohol content (BAC), or to detect viruses or diseases from a breath sample. The name is a genericized trademark of the ..., so that a positive result does not actually indicate that they were driving while intoxicated. Though popular (in 1991, the defence was used in 90% of Swedish appeals against drink driving convictions), the hip flask defence is not always effective. It is possible to back calculate the amount of alcohol and prove an offence nevertheless.

Hops
Hops are the flowers (also called seed cones or strobiles) of the hop plant ''Humulus lupulus'', a member of the Cannabaceae family of flowering plants. They are used primarily as a bittering, flavouring, and stability agent in beer, to which, in addition to bitterness, they impart floral, fruity, or citrus flavours and aromas. Hops are also used for various purposes in other beverages and herbal medicine. The hops plants have separate female and male plants, and only female plants are used for commercial production. The hop plant is a vigorous, climbing, herbaceous perennial, usually trained to grow up strings in a field called a hopfield, hop garden (in the South of England), or hop yard (in the West Country and United States) when grown commercially. Many different varieties of hops are grown by farmers around the world, with different types used for particular styles of beer. The first documented use of hops in beer is from the 9th century, though Hildegard of Bingen, 30 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
