Campden tablets for beer

[foxyaardvark]

I have been using 1/4 of a campden tablet to remove the chlorine from my water before boiling. Will campden tablets still work to remove chlorine if I add them to the completed wort when topping of the carboy or will they only work in water by itself?

Add it to your top off water before mixing it with the wort. That water should really be boiled too, then cooled so it is relatively sanitary before adding to the wort as top off. Even if you boil it the night before then cover with a sanitized lid that's better than nothing.

Will this effectively remove chloramines from the water that is boiled with the wort initially?

I usually add 1/2 tablet to my 5 gallon pot..stir and let sit for 30 minutes prior to boil (to remove chloromine). I am not sure if it makes that much difference to be honest, but it makes me feel better. Do a search on these forums for campden tablets or chloramine for more information.

Campden Tabs? That's what they're for to my understanding. Chlorine can be boiled off. Practically speaking, Chloramines can not.

No, you need to add them to the top off water before adding to the wort. It's my understanding that chlorine and chloramines will react with the minerals in the wort, thus producing chloraphenols and whatnot during fermentation. Don't think the campden can pull those out of the wort.

Plus, if you put campden in your wort and then pitch yeast too soon it can kill the yeast..

 

[Rudeboy]

Are you talking about adding it to the wort before pitching. I wouldn't add campden tablet to the wort shortly before pitching the yeast it will stun the yeast.

For AG brewing you add it to the HLT. Which is about 5-6 hours from pitch time. I wouldn't add it at pitch time. I'd add it before the extract if extract brewing. I'd probably break a small piece off the tablet and use that for when I boil the top off water as well.

I measure out my water and add campden the night before I brew..

There's a lot of misconception about chloramine. People think it's like this crazy bond of chloride and ammonia that is unbreakable. From my research, it breaks with boiling easily. Chlorine evaporates very quickly; it's usually gone by the time your boil is full. Chloramine, chloride and ammonia will break down and evaporate in 20 minutes of boiling. A campden pill for 5 gallons facilitates the break down of chloramine in less than a minute. You can also throw 500 mg of absorbic acid (vitamin C) to completely break down chloramine. And it breaks down in many other ways which is why you don't taste it in food, only in drinking water from the tap.

That is my "understanding".

You may as well quote me if you're addressing me.

I used the understanding line so as not to put myself out as an authority. I guess "practically speaking" depends on whether you have the luxury of preboiling your mash and sparge water for 20 Minutes each then cooling to temp.

Do you think Ascorbic Acid is better then Campden for those of us who must use something to break down the choloramines other then boiling?

It may boil off, but unless you boil your strike water beforehand, the polyphenols in the wort may have already combined with chloramines to form chlorophenols. Not sure if those boil out.

 

[Weeezle007]

Actually, most articles I read about removal state that chloramine cannot be removed from water by boiling, distilling or reverse osmosis. However its usually linked to someone selling a filter that claims to remove it. Its giving me a headache...

Makes sense. Thanks Ty.

You can boil off chloramine, but it's not usually practical as it's hours (and not minutes) to boil it off completely. Chlorine can off-gas as it sits out overnight, or can boil off quickly.

Source about chloramine boiling off completely in hours? How about 90%? And please no faxed document from the early 90's hosted on some beer website.
