The excise duty per centilitre of pure alcohol would be about 10·2p for a typical beer or table wine, arid 17·35p for spirits.
Would it not be far more sensible to use existing carafes of whatever size and mark them in whatever number of centilitres is desired?
Certainly poor fellows like me would have greater understanding if it was, shall we say, rounded to a figure of 50 centilitres.
If my calculations are correct—and they may not be—those are approximate to just over 28 centilitres and just over 56 centilitres respectively.
One then goes into another pub which is also abiding by the code but there the measure is in centilitres.
I believe that it is now bought by measures of 30 or 60 centilitres.
The existing provisions allow for the indefinite marking of gallons, pints, quarts or gills and fluid ounces as a supplementary indication to litres and centilitres.
If it was a minimum quantity of 25 centilitres the chap could put in a little more and be safe.
