So I have decided to make a cider for the first time. I would like to make a sweet sparkling cider. I plan on making a 1 gallon batch, because I have plans for my 5 gallon carboy. I plan on letting my cider ferment dry and then back sweetening. I've read that it's harder to make a sweet sparkling cider vs a sweet still cider. I've never carbed or pasteurized anything before, so could I add campden tabs to cease fermentation and then add priming sugar to carb? Or would the campden render the priming sugar useless? If I don't carb them how still or flat will the cider be? I may just cold crash them as well and keep them all in the fridge to prevent bottle bombs. If I only make a gallon, fitting all the bottles in the fridge is possible. Any feedback would be appreciated.
