Water treatment for extract.

[ashbyp]

I'm doing an extract brew tomorrow morning (Directors clone from the Clone Brews book). As normal I have boiled my topup water and it's cooling in a fermenting bin overnight. That's all I've done in terms of my water so far.

However, I do have some Campden tablets for the first time.

Is this what I should do (assuming I boil 50% of total volume, and the other 50% is from topup water).

1/4 tablet in the topup
1/4 tablet in the boil water, before I start heating...


Cheers!

Thanks for the confirmation Daab.

Is it possible to add too much ie 1 campden tab per 25L or is it just a waste?

Hi Ashbyp

Hope you don't mind the question but I am doing an extract brew the weekend and I am going to boil my water the night before, the last one I didn't and it ended up being a long day, how long do you boil the water for, I'm guessing 10 to 15 minutes is that about right ?

Thanks

I boil for 20mins the night before and dump into a plastic fermenter overnight to cool. The reasoning was:

a) to drive off chlorine
b) to sterilize the water

However, it seems that boiling is not effective for a) since it's chloramine you need to get rid of and boiling doesn't do that. 1/2 a Campden tablet per 25L of water is better.
b) I'm not sure is necessary anyway.

But if you don't have a Campden tablet, then I think the 20minute boil is better than nothing.

Thanks Ashbyp,

I got myself some campden tablets the weekend so 20 minutes it is.
