I just bottled a batch of cider. I had planned on using 5 oz. of corn sugar to prime the five gallon batch for bottling, but then my "creativity" got the best of me. I decided to use some frozen apple concentrate as part of the priming sugar. I checked the label and did some calculations on the fly... I figured 28 grams of sugar is about an ounce, so a can of apple concentrate and 4 oz. of corn sugar should be about right. It didn't occur to me until about two days later that the 28 grams of sugar (from the apple juice label) was 28 grams per serving. Turns out there are six servings per can. So I essentially added ten ounces of fermentable sugar to a five gallon batch of cider just prior to bottling. I may have also added an unmeasured (but relatively small, I think) amount of honey to the bottling bucket.
I've got a fridge I can move these to, and they'll probably be consumed pretty soon thereafter, but how soon do I need to do this? Will the excess sugar cause them to carbonate more quickly than the week or two it usually takes, or will it just cause them to over-carbonate if left too long?
