Hi there Paul and welcome. I agree with vdub, if you have primed the cider at about 5g/1L, keep the bottles in the warmth (comfortable room temp) for a week - a simple trick to know when the bottles are conditioned is to use an old PET coke bottle, when the CO2 is produced the sides of the bottle will become harder to squeeze) once that happens then stick them into the garage or somewhere cooler, this forces the produced CO2 back into suspension in the cider, this will take 2 - 3 weeks. They will be ready to drink at this time but like all good things, they can improve with more ageing.
Hope that helps. Good luck :thumb: :thumb:
