Guess which one oxidized, keg or can.

[Big Nake]

Keg.

Keg.

Winner!

Any more details on the experiment?

Also, kind of related....

Wasnt there an article written about mash pH affecting beer color? Like it made pilsners look awful if it was off??

[Big Nake]

Winner!

Beer is the same age and I assume from the same batch?  Someone on the low-O2 board just mentioned this based on the bottle vs. keg argument.  Do we think that the difference could be a keg that's connected to a CO2 tank all the time?  Also, what was the time frame?  How long was the beer in the keg & can before you poured them?  Not surprised by any of this.

Triangle test those bad boys, see if you can taste the odd one out.

It was not even an experiment just real life.  The beer was canned on December 23rd from the keg.  As I normally do my CO2 is off so at to not drain a tank if I have an issue.  The keg apparently had a slow leak and drained down because when I put the CO2 on last night it took a bit of time to come up to pressure.  I can only guess that the lid let in oxygen and ruined the beer. 

 

I do think there is a relationship to pH and color and I think Ken had mentioned noticing that on his water vision quest he want on a few years back.

 

I have been told to bring my cans to a friends brewery where he will test them on their very expensive DO meter.  I plan to do that next month when I get a few different beers in cans.

I am 100% sure I could because it taste so different but I think I will make my wife do the test.  I have 2 cans left and the beer has not been dumped yet.

As noted the issue was it was NOT on CO2.  I think if it was it would be fine.  I know that goes against the lodo mantra but the only times I have had beer oxidize this bad on tap had 2 things in common, they were NE style beers and the kegs ended up going flat due to a leak.

I actually found that pH color thing.  the pH had to be pretty high.

 

good to know it wasn't the CO2 tank.  I thought I was going to have to buy a canning setup!

I see what you are talking about. 6.5 for a pH is really high!

 

For some styles I am wondering if canning the full run would be batter than leaving it in the keg.  All I know is now I have to replace this beer with another one, look like I will be brewing something this weekend.

if you were planning to can a whole batch would you put it into kegs first?  or maybe "can condition" it in the can?  how bad would canning a whole batch be compared to bottling?

Yes, I would keg first and carbonate.  I do not think I am at the point were I can properly can condition.

 

I would imagine I could do a full batch will take me 45 minutes.

That sounds faster than bottling but maybe I'm remembering it wrong.

I know that filling a can with carbonated beer is easier for me than a bottle was.  I am going to guess it is because of the shape but that is just a gut feeling.

Slightly off-topic but once I started lubing the large o-ring on the hatch of my kegs, any and all CO2 issues disappeared.  I might have a leaky keg which would drain my CO2 tank or else I might have a keg that has been sitting in the on-deck fridge for a month and when I went to put it on tap and relieve the pressure... there was no pressure.  But I have not had issues since making sure that main o-ring is lubed up.  I just swapped out a 5-lb CO2 tank and the date on the tank (when I put it into the draft fridge) was January of 2018!  A 5-lb tank dispensed beer for me for a year!

I normally use keg lube on the o-rings and for some reason I did not do it on this one.  Come to think of it the keg I have ready to go for an APA is not done either.  That one is holding about 5psi right now as I thew the spunding valve on it to cap the fermenter after I dry hopped.

 

This was avoidable and all on me.  Just means I have to brew again this weekend to get the taps filled!

tsk tsk drez!  always lube

I know.  It seems that since I have been purging the kegs with the fermentation blowoff I have not lubed them.  Silly me!!

It's just good to know that this is not normal.  I occasionally have very pale beers on tap and they typically look clearer and better as the keg goes on.  If after 3 weeks of a beer being on tap I saw that darker color come up... I would be aghast.

Interesting. I stopped using homebrew kegs and use sankes instead. Id say my delicate beers last at least an extra month (if they arent consumed) due to the packaging.
