I am thinking about doing some 5 gallon kegs but I am concerned about how long the beer will stay fresh. I know that when we a keg for a party a few years back the beer went flat and stale just a few days after our party. But we used a hand pump to pressurize the keg so I figure all the air in the partly drained keg had a lot to do with that. But if the proper CO2 levels are maintained then no air would get in and carbonation should remain as well. So what is the shelf life of properly kegged beer?

Add 1/2 cup of priming sugar when filling keg you will be good for months

when you pumped the kegs air got in that oxidized the beer.

assuming the beer doesn't have any oxidation already in it (may take some time for it to show) and you purge the head space with CO2 the beer should keep for quite some time.

Like they have already said, when you pump a traditional keg you're just pressurizing it with oxygen, which is bad for beer. If you have your own homebrew and prime your keg with CO2 and keep it that way you have many months of great tasting beer. Even if you don't have the beer on tap and ready to serve the whole time, as long as you purge all the of the oxygen with CO2 when you transfer your beer to the keg and keep it under pressure you should have nothing to worry about.

Cool! Try as I might, I can't finish 5 gallons at one sitting. It's nice to know that I can drink it at a more leisurely pace.

it lasts longer than I can wait, as the keg is finished OFF much sooner than any time that it goes bad.

Unless you will consume 12 oz a week, I don't think time is a plm.

everything but the cath and hot housekeeper: no problem!

some yeast sediment in the keg DEFINITELY EXTENDS the shelf life of room temp kegs.... the beer will weather slightly better than bottles will due to volume. figure a year for a medium+ variety.

My record is 6 years for a barley wine and 3 for a big Belgian. Hoppy beers get a bit bland after 9 months or so, but in a cornie, you can re-hop them.
