As days go past the freshness reduces. In general, the fresher your keg draft beer is, the better it tastes. Keg beer will remain fresh if dispensing with CO2, while maintaining the proper temperature and pressure: For non-pasteurized draft beer about 45-60 days. For pasteurized draft beer about 90-120 days. When dispensing keg beer with a party pump (air), any draft beer will remain fresh for no more than 8-12 hours.
