Has anyone here ever kegged iced coffee? With the summer just about here, I'm trying to keep my iced coffee expenditures down. I've been brewing my own cold-brew to try to bypass the drive-thru in the morning, but if I don't get a chance to make the next day's batch as soon as I get home from work it isn't ready for the next morning.
I was thinking of making a gallon or two at a time and keeping it in a keg so I always have coffee available. My biggest concern is that I only have CO2 gas to push it, and I don't want coffee soda. Can I just unhook the gas and open the PRV until it stops hissing, or will that still leave enough CO2 in the headspace to dissolve in the coffee a bit?
