My question involves how much priming sugar to use now that I am ready to bottle. I have seen instructions that call for 3/4 cup sugar for 5 gallon batches. However, my batch comes in under 5 gallons, more like 4.25 - 4.5. How much priming sugar should I use based on the size of this batch? I just want to be sure that I don't overcarbonate and have exploding bottles going off. Thanks.
