Proof Spirits For excise (tax) purpose, the strength of alcohol in indicated by degrees proof. 1. The US System: Proof spirit is 50% alcohol by volume (or 42.49% by weight). 2. The British / Indian system: Proof spirit is 57.1% ethanol by volume (or 48.24% by weight).57.1 volume of ethyl alcohol is considered to be equal to 100 volumes of proof spirit. This means that any alcoholic solution which contains 57.1 % v/v alcohol is a proof spirit which is said to be 100 proof. So any strength above proof strength is expressed as over proof (O.P.) and any strength below proof strength is expressed as under proof (U.P.) Definition: Proof spirit is that mixture of alcohol and water, which at 51oF weighs 12/13th of an equal volume of water. [N.B. Density of proof spirit = 12/13 of density of water at 510F = 0.923 g/ml] 1. If the strength of the alcohol is above 57.1%v/v alcohol then the solution is called “over proof”. 2. If the strength of the alcohol is below 57.1%v/v alcohol then the solution is called “under proof”. 3. In India, the excise duty is calculated in terms of Rupees per litre of proof alcohol. So any strength of alcohol is required to be converted to degree proof.
