The best IPA I ever made was gone in 2 days

I know that agitating beer while carbonating can lead to temporarily increased carbonic acid which can be undesirable, but had no idea introducing CO2 into a purged vessel could cause oxidation.  Can you point us in the direction of any articles or other documents describing how that works?

Folks here have reported that commercially available CO2 is not 100% pure.  The small amount of O2 can cause staling over the long term.

“Can” being the key word there.  Many people have never had that problem with commercial CO2.

I think the distinction should be made that people who have started utilizing Low Oxygen methods have seen this issue pop up consistently. It seems to present itself more readily under those conditions.

Not trying to detail further though, sorry.

so a simple solution to the problem is to eliminate low 02 brewing methods…

If you spent the time and effort and created one of the best beers you ever brewed, wouldn’t it be a bummer to see it ruined by the O2 content of your CO2?

Agreed, ignorance is not bliss.

Next batch will be transferred to the keg on day 4 with dry hops and spunding valve.  It will be interesting to see how it ages.  Not surprisingly, natural carbonation at the end of fermentation is recommended by JC from Trillium.
