My instinct is is to punish you for your cheeky comments by making you drink some of my home brew, but it really actually is good, so maybe you go without!
UPDATE: I get what you are saying now, not that my home brew will be filthy like cough mixture, but that I should just buy cough mixture and drink that instead of going to the effort of brewing my own. So far it would work out cheaper, but now I've started batch two my total costs bring the cider down to less than two pounds per pint. By the time I make the next 4.5 litre demijohn it'll be more like one fifty pound per pint. If I'm lucky enough to get a five gallon pressure barrel1 for christmas it will go down to 84 pence on the next batch, though if I factor the cost of the barrel in it will be 1.30. Even though I will get the barrel for free for christmas I still have the "opportunity cost", I could have got more socks and jumpers instead.
Not sure that is exactly the barrel I need for cider, but I will investigate and put the idea out there to our "secret santa" group.
Extrapolating further, if I can make an infinite amount of cider I think it will become free.
