Listening now. A good question to ask Chris is whether his keg is on level ground when he purges it with CO2. He may have a half pint or so of starsan left in the keg that he racks on. It probably traps a lot of air and the water could be extra aerated from shaking the keg to sanitize it. I've starsan'd a beer before with way more than you'd want in the finished product and had similar result.

Also, you forgot to post this one!

Good question!  And I didn't forget to post...I've been travelling and wasn't able to.  For some reason, Drew won't do it...kids!  ;)

now that I purge my kegs with CO2 from my primary I can completely flip them over to get out nearly 100% of the starsan and what's left spends days in a low O2 environment.

Ok, that's fine. Were you the guy that called in?

The guy in the podcast lost a lot of flavor in his beer and Denny and Drew's first inclination was oxidation. He never described his procedure for sanitizing kegs and removing sanitizer. Either he's leaving too much in and racking on top of it (closed transfer) or he has contamination issues with a bacteria somewhere from the fill hose to the keg since the bottles he made from the fermenter for competition were perfect. He had the problem with another beer too. So could be just that keg has a contaminant.

I was not.  I was just commenting on an effective way to purge kegs without risking leaving too much sanitizer in there.

How does the source make a difference in how much is left over? Couldn't you do the same thing with a co2 bottle?
Might have to switch to the liquid side though.

This is just my method but now that I do the fermentation purge and not worrying about using up CO2 I will push out the starsan to make sure I get my dip tube and hoses sanatized and then open up and dump anything out.  I will then seal it back up and hook it up to my fermenter.  Before I would not open it up because it was already filled with CO2 and I did not want to waste it.  I do have my gas diptubes cut flush so I can invert and push out as much as I can too.

FWIW, we've gotten a lot of comments on that tasting so we'll probably be revisiting it on the next episode
