Keg purge and oxidation

[stosh]

Put 2 gallons of apricot ale into the corny and put it under 25lbs of psi overnight. This morning I backed the psi down to about 12psi when I realized I never purged the corny after the first time I connected it.

Could that cause oxidation?

Yep. Fruit doesn’t seem to suffer from oxidation the same way hops do though, so not the end of the world. I assume this isn’t a hoppy beer.

Youd have to dig up the threads here tio confirm but i think pressurizing the headspace to 25 or 30 and then blowing off 4 or 5 times gets you to nearly zero o2.

Unfortunately youve already got some o2 into solution since last night, but you can still blow and purge. Cant hurt. Unless im wrong and this is a hoppy beer, in which case youll lose alot of aromatics.
