Hello everyone. Does Chlorine disappear, dissipate during the wort boil.? If the answer is yes then why do we treat our brew water with Campden tablets or pre-boiling or standing over night before we brew? I always pre boil all my water but for no real reason and also use Campden (half) tablet to deal with Chlorine. Cheers guys.

Hi Finn
My understanding is that boiling or sitting overnight will only remove chlorine.
If your water provider uses chloromine, the above two wont remove that.
Campden tablets remove both almost instantly.

OK thanks mate. Funny thing I thought of you this morning.lol cheers for the reply. Here in Christchurch NZ we only have Chlorine. So that means no need to treat as it gets boiled out in the boil right.? We have only had Chlorine in our water in the last 2 or three years as an ongoing effect from the earth quakes, before that just pure water, very lucky but not any more.
Thanks again for the information, now I know. Cheers mate. Take care.

Yep if its chlorine some good splashing while filling and leaving over night should get rid most of it, if not all. I prefer to get rid of it before brewing like that but whether it makes a difference I don't know mate, guess it depends on the level of it as well, the water here reeks of it. Cheers!

Ive just found out that chlorine and chloromine wont dissipate in the boil (of the wort.) Once the polyphenols have attached themselves to the wort (in the mash) they are bound solid and we are stuck with them. So yeah back to treating my water before starting the brew. Very interesting. Cheers guys.
