So you had about 4 bottles left in the keg that had been sitting still long enough for you to drink from the tap all but those 4?

Did you wiggle the keg at all prior to bottling?

The symptoms and tasting notes sound to me like you disturbed some sedimentary yeast and dark malt particles back into solution.

When I bottle with my beergun I enjoy from the tap until its hit that "perfection" stage, then I attach the beer gun without moving the keg AT ALL and bottle what I need.

Yes, I wanted to hand out a few bottles at the end of the keg. Only four could be filled. And yes, I moved the keg around to use the beergun. But the bottle I tried the other day was a slow gusher, and tasted very thin, so I'm not convinced by your explanation.

All the symptoms of infection are present - sour flavor that increases over time, thin body, over carb.  It has to have been during bottling, so take everything apart and clean it.  When I got my beer gun it had instructions on that and came with a brush to clean the insides.  I always take apart the quick disconnects and clean them as well when bottling for competitions.  It amazes me how much crud grows in them.  I've never spent much effort on the gas hose, but I do soak it in sanitizer before use.

Maybe the off flavors come from the sanitizer itself?

So this past weekend I actually used my beergun for the first time, bottled a very hoppy IPA. Did not even think once to clean or sanitize the C02 lines, and even used the same C02 line that I use to carbonate my kegs and attached that to the beer gun, thus thinking the C02 line in the accessory kit was unnecessary.

My processwas I cleaned the bottles with PBW, then used sanitized with starsan, then used the beergun to purge, then fill and cap. Drank the first one yesterday, 3 days after bottling, and it tasted a little funky. My first question, is any tiny amount of starsan left over going to affect the flavor? Is the consensus to sanitize and clean the c02 line going into the beer gun?

No, the sanitizer won't affect the flavor

No, you don't need to sanitize CO2 lines

Are you sure you sanitized the gas line going from the CO2 to the beergun?

Why would that be necessary?  Or is it a joke I'm missing?

That's what I was thinking too, Denny.

Thanks, I know that may have been a stupid question, but just reading this post start to finish had me second guessing myself.

So I tasted another of the 4 bottles that I filled with the beergun, 3 weeks later, and it's clearly an infection. 99% sure it's the beergun, what else would it be?

So what is a foolproof way of cleaning the beergun?  A couple of weeks ago I ran some caustic soda through it, let that sit for a while, and then ran Starsan through it. But Mr OCD in the back of my skull whispers in my ears (not sure how he does that) that this may not be sufficient....

This may be a stoopid question, but you're sanitizing the outside of the beer gun, too, right?  You've run stuff through it to sanitize the inside, but isn't the beer in the bottles exposed to the outside of the gun as well?

Don't laugh. I need to bottle my Roche Four and I'm going to do it the old way with priming sugar and a bottling wand.

I would agree with you if the CO2 line was constantly hooked up to gas, but I completely disassemble my beer gun every time I use it.  I then hang my CO2 line up to dry after sanitizing it after use. If it sits there for 4 months before I use it again, who knows what kind of dust, bacteria, or other wild yeast has had the opportunity to get trapped up in there?  Sanitizing it prior to use simply helps me to be sure that I have potentially eliminated any issues with my bottling process with regards to sanitation.

I can tell you that I have bottled batches off my kegs that have gone into comps and gotten scores with wild yeast infections noted (plastic notes). Then a couple weeks later bottling them up from the same keg and taking best of show with the same beer. So, I have definitely picked up infections when using the beer gun before. Will I still continue to use it?  Of course, I think it is a good product.  Sometimes s**t happens and it is out of your control.  Oh well, it is just beer. And I love it!

Yep, put the beergun in a bucket of starsan...

I also run iodophor through mine prior to packaging.

I do! Funnily enough to me (and many others) some Belgian beers are better on draft. Two local beers come to mind: De Koninck and Westmalle Dubbel.
