A bottle is 70 centilitres.
Wine may be sold in 25 centilitres, 50 centilitres—that is his half litre—75 centilitres, one litre, or two imperial measures of 10 or 20 fluid ounces.
Not only is there the example of 75 centilitre wine and spirit bottles but also beers and soft drinks sold in 440, 330 and 275 millilitre cans.
The effect of a centilitre of alcohol is the same in whichever form one takes it.
That is equivalent to one-third of the contents of a standard 75 centilitre bottle of wine.
Why, therefore, have the centilitre and the decilitre not been included?
He would in practice be infinitely more likely to use "20 centilitres"or"2 decilitres".
If it was a minimum quantity of 25 centilitres the chap could put in a little more and be safe.
