Alcoholic spirits measure The 1963 Act formalized the legal measures by which spirits and other alcoholic beverages should be dispensed, namely 1/4 gill (35.5 ml), 1/5 gill (28.4 ml) or 1/6 gill (23.7 ml), but this was replaced in 1985 by 25ml and 35ml for single measures, with double measures of 50ml or 70ml being permitted in 2001. Landlords have the option to decide which quantities they sell, with the difference being caused by historically larger measures being used in Scotland and Northern Ireland.
