Editing Alcohol proof (section)

===United Kingdom===
On 1 January 1980, Britain adopted the ABV system of measurement prescribed by the European Union, of which it was then a member. The OIML recommendation for ABV used by the EU states the alcohol by volume in a mixture containing alcohol as a percentage of the total volume of the mixture at a temperature of {{convert|293.15|K|disp=sqbr}}. It replaced the [[Bartholomew Sikes|Sikes]] [[hydrometer]] method of measuring the proof of spirits, which had been used in Britain for over 160 years.<ref name=scotch/><ref>{{cite book |last=Regan |first=Gary |year=2003 |title=The Joy of Mixology |publisher=Clarkson Potter |location=New York |isbn=0-609-60884-3 |pages=356–357}}</ref>
