This method is so cheap easy that I cannot tell you why it took me 27 years to start making my own cider!!
It requires no skill, no special equipment and no sterilisation and you can be drinking your own amazing homebrew cider in as little as 3 weeks.
You will need:
5L water bottle
4.5L Apple Juice
a sachet of cider yeast
The beauty of this method is that since everything you are using is sealed in a sterile package, there is no need to clean or sterilise anything.
The bottle of water we are interested in only for the container itself, so pour out all of the water (it is better if you don't waste it, fill up the kettle or put it to use, just don't drink it directly from the bottle as we want it sterile!)
The apple juice MUST be 100% apple juice, not apple juice drink. It is ok if it is from concentrate, just check that it is 100% juice and nothing else, anything with an additive/preservative in it will likely kill the yeast and stop you making any cider. At the time of writing this post the cheapest apple juice was either 55p per litre Sainsbury's basics, or 88p per 1.5L at Lidls.
Pour the apple juice in to the 5L container, leaving a few inches at the top of the bottle to accommodate any frothing/foaming caused by the yeast later.
At this stage add the magic ingredient, a cup of VERY strong tea (use 4 or 5 teabags, no milk)
This is the easiest way to get tannin in to the mixture.
Add the yeast last, in theory you could use half the packet but I always tip a full one in just to be sure as they are not expensive.
Stretch the balloon over the neck of the bottle as a makeshift airlock to keep contaminants out whilst still allowing the gasses to expand and the rest is just a waiting game
After around 3 weeks the cider should have cleared up nicely and you will be left with a delicious flat cider similar to scrumpy. I prefer my cider fizzy, so at the 3 week mark I pour the cider in to individual bottles, add a spoon of sugar to each and cap them off for another week. if the C02 produced by the yeast cannot escape it's container then the bottle will become pressurised and the drink will become carbonated, i.e Fizzy :)
At that stage you can put it in the fridge to chill and enjoy a great home made cider which depending on which yeast you've used should finish out around 3-4% ABV. If you wanted to turn a great cider in to an amazing cider, then try adding a full jar of honey when you put the strong tea in, this will give the yeast more sugar to feed off and will finish the cider off at around 6-7% ABV
