【How-to】What is a keg flip

Long answer: It depends on the kind of pint, the size of the brewery, and the kind of kegerator you have. As a general rule, stouts and porters will give you the most time, with up to 6 weeks in which the pint will still be drinkable. With a single or double IPA, the keg needs to be finished in no more than 4 weeks.
