Practice reduced the tendency of both groups to over pour for tall, slender glasses but not for short, wide glasses. These misperceptions are attributed to two perceptual biases: (1) Estimating that tall, slender glasses have more volume than shorter, wider glasses; and (2) Over focusing on the height of the liquid and disregarding the width. Standard drinks
There is no single standard, but a standard drink of 10g alcohol, which is used in the WHO AUDIT (Alcohol Use Disorders Identification Test)s questionnaire form example, have been adopted by more countries than any other amount. 10 grams is equivalent to 12.7 millilitres. 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. The standard drink varies significantly from country to country. For example, it is 7.62 ml (6 grams) of alcohol in Austria, but in Japan it is 25 ml (19.75 grams). In the United Kingdom, there is a system of units of alcohol which serves as a guideline for alcohol consumption. A single unit of alcohol is defined as 10 ml. The number of units present in a typical drink is sometimes printed on bottles.
9th–10th centuries AD: Medieval Muslim chemists such as Jābir ibn Ḥayyān (Latin: Geber, ninth century) and Abū Bakr al-Rāzī (Latin: Rhazes, c. 865–925) experimented extensively with the distillation of various substances. The distillation of wine is attested in Arabic works attributed to al-Kindī (c. 801–873 CE) and to al-Fārābī (c. 872–950), and in the 28th book of al-Zahrāwīs (Latin: Abulcasis, 936–1013) Kitāb al-Taṣrīf (later translated into Latin as Liber servatoris). 12th century: The process of distillation spread from the Middle East to Italy, where distilled alcoholic drinks were recorded in the mid-12th century. In China, archaeological evidence indicates that the true distillation of alcohol began during the 12th century Jin or Southern Song dynasties. A still has been found at an archaeological site in Qinglong, Hebei, dating to the 12th century. 14th century: In India, the true distillation of alcohol was introduced from the Middle East, and was in wide use in the Delhi Sultanate by the 14th century. By the early 14th century, distilled alcoholic drinks had spread throughout the European continent. See also
