Specific gravity is the density of a liquid relative to that of water, i.e., if the density of the liquid is 1.05 times that of water, it has a specific gravity of 1.05. In UK brewing usage, it is customary to regard the reference value for water to be 1000, so the specific gravity of the same example beer would be quoted as 1050.
A standard drink is a notional drink that contains a specified amount of pure alcohol. The standard drink is used in many countries to quantify alcohol intake. It is usually expressed as a measure of beer, wine, or spirits. One standard drink always contains the same amount of alcohol regardless of serving size or the type of alcoholic beverage.
A 750 ml (25 US fl oz) bottle of 12% ABV wine contains 9 units; 16% ABV wine contains 12 units; a fortified wine such as port at 20% ABV contains 15 units. 100 ml (3.4 US fl oz) glass of wine (13.5% alcohol) = 1 Australian standard drink; 150 ml (5.1 US fl oz) glass of wine (13.5% alcohol) = 1.5 Australian standard drinks
The United Kingdom today uses ABV instead of proof. In the United States, alcohol proof is defined as twice the percentage of ABV. The definition of proof in terms of ABV varies from country to country. The measurement of alcohol content and the statement of content on bottles of alcoholic beverages is regulated by law in many countries.
A basic formula [4] to calculate beer strength based on the difference between the original and final SG is: A B V = 131.25 ( O G − F G ) {\displaystyle ABV=131.25(OG-FG)} The formula below [ 5 ] is an alternate equation which provides more accurate estimates at higher alcohol percentages (it is typically used for beers above 6 or 7%).
Liquor may be consumed on its own (i.e. "neat"), typically in amounts of around 50 millilitres (1.7 US fluid ounces) per served drink; or frequently mixed with other ingredients to form a cocktail. In an undiluted form, distilled beverages are often slightly sweet and bitter and typically impart a burning mouthfeel with an odor derived from the ...
The average number of people who drink as of 2016 was 39% for males and 25% for females (2.4 billion people in total). [4] Females on average drink 0.7 drinks per day while males drink 1.7 drinks per day. [4] The rates of drinking varies significantly in different areas of the world. [4]
where = (/) gives the number of grams of alcohol per 100 grams (3.5 oz) of beer i.e. the ABW. Note that the alcohol content depends not only on the diminution of extract ( p − n ) {\displaystyle (p-n)} but also on the multiplicative factor f p n {\displaystyle f_{pn}} which depends on the OE.
