Hey fletcher
It is a ridiculously simple way of making cider. Keep it simple.
I don't even cling wrap the tops, use the original bottle cap from the start. I just release the gas a couple of times a day. When it stops going hard in half a day I stop doing this and put it in the fridge. Great things about using the original juice bottle:
Bottle, as bought from shop is sterile inside. Avoids having to sanitise.
Bottle is flexible, takes some blowing up or squeezing the air out.
Hard to create a bottle bomb with in the fridge.
It's effin simple to do!
Doesn't get boring with loads of girly juice tying up kegs or shelf space.
We don't have much cider apples available here anyway, without that the ciders everyone makes taste just the same anyway. I've been trying what I can, travelling, drinking from a small cidery or two, useless. If I want a complex cider, I'll buy it.
