Alcohol UnitsWe measure alcohol consumption in units. A UK unit is 10ml or 8 grams of pure alcohol. The number of units in a drink depends on what you're drinking - how strong it is and how much there is.
The ABV level on a bottle label indicates how much alcohol it has by volume: for example, 1 litre of 5.2 ABV lager has 5.2 units of alcohol; a 75cl bottle of wine which is 12% ABV has 9 units
Overview and Alcohol Historical ConsiderationAlcohol has been described as the nation's favourite drug. Accessible, socially acceptable and legally saleable - mankind's love affair with alcohol can be traced back through centuries. The first identifiable beers can be traced back to Egypt in 5000 BC.
Humans are a unique species for many reasons, one of which is our predilection for mind altering substances. We are the only species which actively seeks out and ingests these substances in our environment - at least, for 93% of men and 87% of women.
In its purest form alcohol is a substance called ethanol. Alcohol, or ethanol, is the intoxicating agent found in beer, wine and liquor. Alcohol is produced by fermentation of yeast, sugars, and starches.
