Default Plagued by Metallic Taste Looking for Suggestions

Hi there.

I am battling a irritating metallic taste in pretty much all of my brews so far. I am on brew #6, and my most recent (Jamil's Raison de Saison) is my first all grain, and I can smell and taste a bit of it already tonight while I was checking the gravity (although it has a lot of drying out to do still and is very sweet). I have tasted this in all my previous extract and PM brews (Porter, Oatmeal Stout PM, IPA, Wit and Hef).

I am using a pair of basic stainless 20 QT brew pots for strike and sparge water and a 10 gallon stainless brew kettle from Instawares. I also use a brand new copper wort chiller (again, only for the last few brews) and I even recently switched to using Star San instead of OneStep. I have a Brita filter on my faucet and the water tastes pretty much fine out of the tap.

So, besides using a different approach to water, I have tried to eliminate the most obvious causes – sanitation, etc.

Another homebrewer in my same neighborhood is using the same water and all he does is use the 5.2 pH stabilizer, but again, before going all grain I noticed it.

So I am looking for some suggestions on what I should consider looking at next.

Could it be the pipes in the house between the supply and the faucet? Is it possible that my water can taste OK out of the tap using the Brita charcoal filter but changes during fermentation? Should I switch to spring + distilled?

I'm stumped.

Thanks in advance.

Daniel

Can you get a copy of your water report?

I suppose I could. I guess I was suspecting something in my process (pots, pipes, etc) since I know a few people in my neighborhood that are having decent results using the same water supply.

I'll give a call and request a report, though.

Thanks for replying!

You could also try brewing a batch using your friends/neighbors water and see what you get...

Other than water what is the only constant with all of your batches? It seems you changed alot of things but still have this flavor. so what has always been used? same water and what else?

Well, for the last three batches, I used the same brew kettle, which is brand new, and is stainless (has a machined metal finish), so unless the manufacturer was lying about it's construction, stainless shouldn't imparting flavors, right? Below is a pic of it.

Besides that, I can only say I did starters for each, using a basic glass growler, cleaned and sanitized, topped with aluminum foil. Did those a few days before and kept them at room temp until just before pitching.

Might do your next brew with bottled spring water. Also, how do you clean your pot? I always used bar keepers friend and a sponge only used on my brew pot.

Your filter may not be taking out all the iron or manganese that is in your water. Small amounts of these can affect flavor. Can you try using bottled water or another source for your water?

I sure can try to use spring water maybe? Or should I be cutting my tap water with distilled?

Suggestions for approaches are welcomed. I am new at this...

Thanks again to everyone for the replies.
