home brew - would this work???

There is no discernible loss of liquid bar what is in the yeast sediment you get rid of. Average for cheap apple juice (from concentrated juice) is about 60p a litre at the moment. In a gallon demi-john you could make about 4.5 litres. Average for a 1kg bag of sugar is about 80p at the moment so £3.50 for 4.5 litres of cider, not taking into account equipment or yeast costs.

You have to take into account however, that it is made made from apple juice and sugar rather than possibly containing flavourings, apple essence etcetera and the home made stuff is live rather than having been pasteurised and so has a much better taste.

For a commercial product that is going to compete on terms of flavour, you are going to be looking at spending £3.50-34 litre - what you could make 4.5l for yourself.
