So I'm going about my normal routine here.  I put calcium chloride, gypsum and brewtan (a little over 1/2 tsp in over 11 gals) in my strike water as I got it up to temp.  I noticed after adding the brewtan that the water looked slightly greenish.

 

now I've put my strike water into the mash tun (cooler) and I just went out to check the temp and now the strike water is a dark green color.  no grain has been added but I'm sure there is a little bit of grain residue in there from the last batch.  thing is, this didn't happen the last time I used brewtan (n=1).

Pictures my man .. Pictures.

 

I have no response because I heat my water up and ten add it to the MLT and then add the salts and brwetan.

looks like swamp water:

 

 

you can also see the mash residue that was left from the last batch.  is the brewtan interacting with this?  i've never super thoroughly cleaned that stuff out of the mash tun to be honest

WOW .. that looks nasty!

[positiveContact]

yeah.  i'm not sure if I should just continue or what

that water was crystal clear before adding the brewtan.

I know what i would do here... but I am not sure you want to hear it.

Yeah, there's got to be something reacting or left over. Dump the water and start over.

how do I know this won't just happen again?

I would dump it and test a small amount of water in there.

what about the water I used to make my starter?  it was in the kettle but never had brewtan in it.  just campden tablet.

And that was clear right?  I would say that is fine.

 

Did you try tasting the gross water?  Not saying I would just wondering

[positiveContact]

i did not.  i don't think it smelled strange though.

The only thing brewtan did for me was create a slightly orange-ish / tannish foam which I think I posted a picture of. Never saw anything like that. Brewtan is supposed to react/bond/chelate anything metallic right? Is it possible that there is a high level of copper or iron in this water? I have been following the brewtan thread on AHA (now on page 57 or so) and no one has mentioned this.

I am sure i did a bad thing but I gave Morty Denny's and Joe's e-mail to try and contact them about this.  I have not seen any mention of this in the experimental brewing tests either.

i don't recall having high anything in my water.  it's city water.

so i just thoroughly rinsed my kettles and mash tun.  now what?  do I still use brewtan B for this batch or no?

[HVB]

i don't recall having high anything in my water.  it's city water.

But is it LODO!!  You have too much O2....

The water in the kettle was green too or only when you put it into the MT? I would do it again with brewtan, personally although I understand the apprehension. The only question not asked already is: shouldn't you be working now?

it was slightly greenish in the kettle but after putting it in the mash tun it started getting darker and darker.

We do have Joe Formanek's email address too but I'll be honest... I emailed him right when the podcast came out and he never responded. I'd try it one more time and if it happens again, screw it until you find out why. I know that's another hour or something but that's what I would do.

He did reply to some of the Experimental Brewing e-mail chains.
