Beer life in Corney?

[penutbuttrdeath]

Ive been reading alot on kegs and kegging beer instead of bottle but havent really seen how much beer life most people get out of a keg. Can you age a beer in a Corney keg for 8months to a year and still come out with a tasty brew? What about after you tap it... How long can you let it be tapped before it might go skunky. thanks for any input... im slowly learning

Life of beer in keg: unlimited.*
(* As long as you treat the beer properly and follow proper techniques.)

Main enemies of beer:
1. Heat. Keep the keg cool. The colder the slower all the again processes occur.
2. Oxygen. Purge the keg well and keep it under CO2 pressure.
3. Light. Not a problem with kegs, they are light impermeable.
(4. (not really an enemy of beer per se, but can ruin an otherwise good beer) Bacteria/wild yeast. Be very, very thorough with sanitation. The longer the beer sits the more obvious lacking sanitation will be noticeable.)

I have 2 questions to the things you listed:
1. Is it bad if the keg gets too cold? Like 35-33F?
2. How do you purge a commercial keg that has a sankey tap??

1. No, 33-35 is a great temp for storing kegs.
2. For homebrew? IDK, someone else though. If it is commercial, then it comes purged. Pushing the beer with CO2 over a hand pump will keep it fresh.
