Re: Boiling Water

What happens is that you kill most of the microorganism, and since this is repeated daily, and considering that the ...

I was thinking perhaps there is something which usually during pasteurisation is killed but as it's unpasteurised there may be something which is inhibiting this extraction method. Any suggestions are welcome! Thanks ...
