By any chance did you accidentally get a CO2 bottle with mixed gas?  I ruined a nice Dortmunder by carbing it with Nitrogen mix.  It sounds like the same flavor you are describing.  The Airgas people didn't seem know much difference.

If it's beer mix, wouldn't it require a MUCH higher pressure to achieve decent carbonation levels?

I thought the nitro doesn't go into solution, or only goes in slowly and not so much.  If that makes sense.

But your gas/tank was going to be my suggestion.  Do you have a different tank you could try?

Unless it's flat I don't think the gas mix is your problem, it works like Joe Sr. said.  Jeff, if your batch tasted funny I would suspect some other problem before I blamed the gas.

Some contaminations can taste metallic, copper has been mentioned, it could be something else.  Have you changed your water source?

Chlorine or chloramine are obvious sources of this problem.  Carbonating beer can make off-flavors more obvious. 

Over-carbonated beer can also have a metalic bite from the carbonic acid, which seems possible if it is appearing after the beer is carbonated.

We don't use chloramine here in Eugene where Ben and I are located.  But I agree that it could be chlorine.  I know he filters his water, but I also know that isn't foolproof.  That's why I'm encouraging him to get me a sample.

I will denny. My hunch now is something to do with the gas/regulator leak maybe over carbing. This has been about a year now with bad beer. Been a tough one for sure. Im certain my brewing process is perfect. Copper only touched my wort when chilling

You could try priming in a keg and carbing naturally to see if that makes a difference.

Of course, that's taking a risk on another batch.

If it's somehow related to the gas, would de-gassing eliminate the flavor?

I've never gotten a bad tank of gas, but maybe?  You could have someone else carbonate one of your beers.  But getting that sample to Denny is a good idea too :)

You would be the only one, I think. ;D

Yes, filters are not particularly efficient and it's easy for chlorine to get past a filter.

Have you disassembled the keg(s) completely and verified there are no places where rust has started coming in?  Perhaps you cut your dip tube and the end is rusting, or there's a scratch in there somewhere where there's a rusting process going on?  Even stainless can rust if it is cut/scratched with non-stainless steel tools and it is not re-passivated.

I think the idea to bottle some and keg the rest is a really good test. 

Is it possible that you over-oxygenating?  Jamil said in several podcasts over the years that too much O2 will produce fusely/metallic off flavors.  More than 2 minutes of pure 02 and you start affecting flavor.  Perhaps your mini-batch was not as oxygenated and therefore it didn't produce the off flavors?   You said you are attempting to get more attenuation and this may be playing into it.

I'll also add to the pile of suggestions to let a couple/few experienced palates evaluate it for you.

Brewed a Bavarian heff 4-5 weeks ago. Got new kegs new regulator. New ball locks connectors etc...

Did a double decoction and used wyeast 3638. Started at 65-worked to 68-69 over the week.

Its been a year and many batches since the beer has been drinkable. Tapped my first beer tonight. Absolutely loved it. Super happy right now. Phenomenal beer.

Only been kegged for 5 days so its not completely ready but here is a little picture.

Nice to hear that your heff turned out great.  Was the problem the kegs and fittings?
