Sterilise your equipment.
Open the cartons and pour the apple juice into your fermenter.
Sprinkle on the yeast.
Put the lid on / bung and airlock.
If using an airlock, 1/2 fill the bottom 2 bubbles with sterilising solution.
Leave to ferment for 7-10 days in a arm place where the temperature is constant between 18-22°C.
Once the fermentation is complete and no bubbles can be seen rising to the top of the cider and none through the airlock, then it time to bottle.
Only use bottles that are suitable for a carbonated liquid.
Put 1/2 teaspoon of sugar into each bottle.
Syphon the cider into the bottles and add the caps.
Shake the bottles to dissolve the sugar
Put back in your warm place for 48 hours for a secondary fermentation in the bottles to make the cider fizzy.
No put somewhere cool to clear.
They should be clear in about 1-2 weeks.
Pop some bottles in the fridge to chill, then pop one open and enjoy.
All cider is dry, so if you want a sweet cider, before you open the bottle, put 2-4 teaspoons of sugar in the bottom of a pint Glass. Pour on 1 Tablespoon of boiling water and stir until the sugar is dissolved. Now open your cider and pour it into the glass. Give it a quick gentle stir to mix the sugar syrup and the cider and now you have a medium (2tsp sugar) or sweet (4tsp sugar) cider.
Please remember home made cider can be much stronger than commercially made cider, so go easy on it.
