stronger. In pubs in the United Kingdom, beers generally range from 3.5 to 5.5% ABV, and continental lagers start at around 4% ABV. An imperial pint of such lager (e.g., 568 ml at 5.2%) contains almost 3 units of alcohol rather than the oft-quoted 2 units. Stronger beer (6–12%) may contain 2 units or more per half pint (imperial). A half-litre (500 ml) of standard lager or ale (5%) contains 2.5 units. One litre (1000 ml) of typical Oktoberfest beer (5.5–6%) contains 5.5–6 units of alcohol. A beer bottle is typically 333-355ml, approximately 1.7 units at 5%. Wines A medium glass (175 ml) of 12% ABV wine contains around two units of alcohol. However, British pubs and restaurants often supply larger quantities (large glass ≈ 250 ml), which contain 3 units. Red wines often have a higher alcohol content (on average 12.5%, sometimes up to 16%). Wine sold by the glass is often served in nearly full glasses. Wine served at home, or when bought by the bottle in, say, a restaurant, is usually served in glasses less than half filled; the capacity of a wine glass is not the only criterion for judging quantity. A 750 ml 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. Fortified wines A small glass (50 ml) of sherry, fortified wine, or cream liqueur (≈20% ABV) contains about one unit. Spirits Most spirits sold in the United Kingdom have 40% ABV or slightly less. In England, a single pub measure (25 ml) of a spirit contains one unit. However, a larger 35 ml measure is increasingly used (and in particular is standard in Northern Ireland), which contains 1.4 units of alcohol at 40% ABV. Sellers of spirits by the glass must state the capacity of their standard measure in ml. Alcopops According to Alcohol and You Northern Ireland resource website, "Most alcopops contain 1.1–1.5 units per bottle. For example, a normal 275 ml bottle of WKD contains 1.1 units, whereas Bacardi Breezer and Smirnoff Ice both contain 1.5 units of alcohol." Time to metabolise On average, it takes about one hour for the body to metabolise (break down) one unit of alcohol. However, this will vary with body weight, sex, age, personal metabolic rate, recent food intake, the type and strength of the alcohol, and medications
