RO Water and additives

(1/2) > >>

jtconrad74:
I use RO water for brewing, should I be adding anything to that type of water for hardness....etc?  My brews are just extract using steeping grains so it's nothing too crazy.  My first two batches seemed to finish a little "off" in flavor so I thought I would see if it may be my water.  It does taste fine though.

Kaiser:
I don't think the off-flavor comes from the lack of salts. The only salt that may be benefical to you is gypsum (calcium sulfate). The additional sulfate is known to accentuate the hop presence. Aside from that the extract contains all the minerals you need.

Describe "off-flavor" please?

It could be oxidized extract.

jtconrad74:
Not sure, kind of old I guess.  It just didn't taste right.  I am thinking I got some extract that was a little too old on the shelf?
I made a pilsner.

I have yet to taste the english brown ale I made for my 2nd brew, maybe that one will turn out.

I have also switched to using star san so i might have gotten some contamination since I'm still green at doing this.

dimik:
I used RO water with no additives when doing extracts, and had no problems.
My guess is there is something with your procedure... ferm temps perhaps? Or it could be old extract.
