Ive had multiple batches with a metallic taste to them and cant figure it out. I hit all my numbers while brewing. I brew in a keggles so i know its not a ceramic problem as i have read. I brewed at my house with soft water same problem. Moved everything tobmy dads with well water same problem. Ive read it could be my water but i dont have a test kit to confirm. Also read it could be green also but hydrometer readings confirm its not.

Driving me nuts! Is it the water?

Extract or All-Grain?

I had several batches that had a metallic taste back when I used to brew extract, narrowed it down to a bunch of Amber LME I'd purchased from a local BOP.

How can a hydrometer reading tell you if your beer is still green?

All grain

And how can it not be green when is been fermenting for 2.5 weeks and hydrometer has same reading for 3 days in a row? Unless i need to let it go longer?

2.5 weeks isn't really a long time. Let it condition and carb up before you give it a final taste.

It sorta smelled like metallic in the fermenter but i carbed it over night and today the taste was over whelming. Should i take it off the co2 and let it condition or ride it out?

Even though a beer has reached final gravity it can be, and most likely is, green.

Few things you can try...
Don't use metal pads to clean the brewing equipment, especially the stainless. Use scotch brite pads on stainless, or similar items. Make sure that ALL the metal coming into contact with the wort/beer is neutral (either brass, bronze, or stainless steel). If ANY of it is non-stainless steel, replace it.
Either filter the water with a high quality (not saying expensive, since prices have come way down over the years, probably get something for about $100, or less), multi-stage, filter system, or start buying water that's either distilled, RO, or otherwise has virtually everything removed from it. Poland Springs water comes to mind.

Are you milling your own grain, or are you getting it milled?

Also, you can do a quick google search to find causes and solutions to the metallic flavor. You might want to grab this pdf: kotmf.com/articles/flavor.pdf

Also, 2.5 weeks in primary isn't that long, and as others have already mentioned, no guarantee it's not also green. Carbonating overnight (assuming your kegging) could be enhancing the off flavors.

If you want to really find out what's in the water you're using, you'll need to send out samples for testing. Although it could be easier to just get a good dual stage filter setup installed under the sink and use that for brewing/cooking/drinking. The water I get out of my filter has pretty much zero flavor to it. Best described as 'wet'... When I start to detect anything (or I've sent enough gallons through the filters, whichever comes first) I change both filters.

I use ss mesh balls as my hop stopper. Copper dip tubes. Didnt think that would cause any problems since everyone uses those!

Can that cause metallic flavors?
