Alcohol drinking day average drinks consumed range
The counted number of drinks containing alcohol consumed by the participant/subject on a typical day when he/she is drinking. It is noted that the meaning of "drinks consumed" differs from one nation and culture to another, so the most common alcoholic beverages likely to be consumed will be defined as well as quantity of each that constitutes a drink (approximately 10 grams of pure ethanol). For example, one bottle of beer (330 ml at 5% ethanol), a glass of wine (140 ml at 12% ethanol), and a shot of spirits (40 ml at 40% ethanol) represent a standard drink of about 13 g of ethanol
