Boiling the kettle would actually agitate the reason why most people use distilled water. When you boil the water, the impurities in the water don't evaporate with the water but rather concentrate in the remaining water. Distilled water is superior because it has none of these impurities. for less than a dollar a gallon jug at every supermarket I have been to, it really is worth the extra effort to go out and get some.
The more love you put into your extraction the better the final product will be!!!!!!
