Since I wrote the original article on alcohol tax and prices nearly two years ago things have moved on a bit. The big idea now is that the minimum over the counter price, after tax and everything, should be 45p per unit of alcohol. To save you reading the original article again, a unit is calculated as 1% in 1 litre of liquid. So using these figures this is the revised table.
3.5% beer—pint—Minimum over the counter price 90p
Flandres 2.6% gnats—250ml bottle—Minimum price 29p
Special Brew 9% fighting juice—500ml can ==> Minimum price £2.03p
A nice 14.5% Rioja—75cl bottle—Minimum price £4.89
Budget 30% vodka—70cl bottle—Minimum price £9.45
Bacardi 151 death wish—litre—Minimum price £33.98
I haven’t had a chance to check current supermarket prices yet, but it will make a significant difference wiping out cheap wine. I will update later.
