I currently only bottle beer, but I would like to have the flexibility of kegging beer to bring to a party from time to time. I do not want to commit to a kegerator. I will be happy to try to keep the beer on ice during the event. What is the smallest amount of gear that I can get away with to accomplish this and about how much will it cost?
Something like this setup would be the minimum for 5 gallons of beer:
A 5 gallon keg, CO2 tank, regulator, and tap.
