I've searched the forum and I can't find the right answer for this one...
I brew 3 gallon batches because I like the smaller size as I am the only beer drinker in the house and I can brew more often. I have a mini fridge that holds one keg, (5 gal). I have two 5 gallon kegs and don't really want to spend the cash on a couple of 3 gallon ones. I would like to carbonate one with sugar while I am drinking the other. I only have room for one in the fridge. I can purge the air out of the keg but I can't figure out how much priming sugar I need to carbonate 3 gallons in the 5 gallon keg. It seems to me that I would need extra to make up for the head space in the larger keg. I usually use 2 5/8 ounces to bottle condition a 3 gallon batch.
