Topping up the keg

[Sadu]

New to kegging. Brewed a 24 liter schwarzbier.

Racked to a corny keg and the leftover that wouldn't fit went into a 5 liter glass demijohn, lagering in the fridge. Force carbed the keg.

I have been drinking from the keg and enjoying not having bottles to clean and sanitise. I must have got through about 5 liters by now and thinking that the demijohn is getting in my way and it would be nice to get rid of it.

Can I depressurise the keg and rack that 5 liters of uncarbed beer into the keg, then purge the headspace and force carbonate again? I realise that opening the keg without reason isn't ideal, but is this a valid gameplan?

If that's a no go then I'll have to bottle condition that 5 liters of beer.

Sure you can. You'll get a bit of oxidation, and also lose a bit of aroma by releasing CO2 from the keg, but it'll probably be barely noticeable.

I don't understand why oxidation is a call out. He wouldn't be adding any more oxygen than he normally would by kegging the remaining beer into it's own keg. I'm sure I'm missing something.

Anytime you introduce more oxygen there will always be consequences. It's a fairly obvious thing to understand.

Cool, so I racked it today into the keg, purged, started force carbing again. Thanks for replies.
