Campden Tablets for Chloramine Removal

(1/2) > >>

mrdrysdale64:
I have read a few things about using campden tablets (potassium or sodium metabisulphite) in tap water to remove chloramines but I cannot find any articles with hard data on if and how it works.

Does anyone have some solid information they could share? Has anyone had their water tested by Ward Labs after using campden? Can Ward even test for chloramines? Does the potassium or sodium metabisulphite have any effects on the quality or taste of the beer?

denny:
No effect on flavor at all used in the proper amounts. 

Beertracker:
John Palmer briefly discusses this topic in his book. I'm not a brewing chemist (nor do I play one on TV  :D), so I don't know how it works, but it works! I do know that you don't want too much sulfite in your finished beer because it can stunt or kill the beasties.  :'(

denny:
If you're curious about the chemistry, search HBD for posts by A.J. DeLange.  He explains it better than anyone.

This may be slightly off from chloramine but here's a small discussion on it:
