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.
Using standard tapper provided with keg at time of purchase... 3 to 5 days or less. Using a kegerator system with CO2 ... 2 months or longer depending on how cold your frige is. Air and heat is beers natural enemy. When using a hand pumped tapper the air forces the beer out nicely but it starts the cycle of the beer going flat.
