Product Information

We're supposed to be keeping an eye on how much we drink, but how many of us really know what a unit of alcohol is? The Weights and Measures Act of 1963 made it illegal in Britain for businesses to give short weights or short measures to consumers. Before this there was no legislation, only guidelines as to the correct weight of an alcoholic spirit measure, and if spirit measures or optics were used, they required a government stamp to certify that the measure was accurate. This act specified that only gin, rum, vodka and whisky were spirits and had to be served in the prescribed measured quantities using an approved optic measure. All other drinks are not spirits (for the purposes of the act) and could be free poured. Today, these other drinks may not be free poured, but must be measured, though the bar is free to choose the size of the measure (which must be advertised). In practice, most bars will use the same size measure as for the four spirits. [5] With so many different drinks and glass sizes, from shots to pints – not to mention bottles – it's easy to get confused about how many units are in your drink. Since a centiliter is 10

Alcoholic spirits measures are instruments designed to measure exact amounts or shots of alcoholic spirits. Thimble measures are also used in 175ml and 250ml volumes for measuring wine. Although government stamped for the correct volume, the thimble measure does rely on the user measuring the wine out manually into the thimble.units is equivalent to 6 pints of average-strength beer or 10 small glasses of lower-strength wine. Calculating units

You can work out how many units there are in any drink by multiplying the total volume of a drink (in ml) by its ABV (measured as a percentage) and dividing the result by 1,000. Using units is a simpler way of representing a drink's alcohol content – usually expressed by the standard measure alcohol by volume (ABV).One unit equals 10ml or 8g of pure alcohol, which is around the amount of alcohol the average adult can process in an hour. ABV is a measure of the amount of pure alcohol as a percentage of the total volume of liquid in a drink. The 1963 act formalized the legal measures by which spirits and other alcoholic beverages should be dispensed, namely 1⁄ 4, 1⁄ 5 or 1⁄ 6 gill (36,28 or 24ml), but this was replaced in 1985 when 25ml or 35ml were permitted. [5] Landlords have the option to decide which quantity they sell, with the difference being caused by historically larger measures being used in Scotland and Northern Ireland. The landlord can choose one or the other but not both.
