[Homeroast] Distilled H2O

Any of us lab rats will tell you that boiling pure distilled water is 
dangerous as it can "bump" or "explode" for lack of particulate surface 
around which to form vapor bubbles.  Be very careful.  In a metal boiler 
chamber there should be sufficient surfaces to prevent that, but you 
never know.

Much municipal tap water is treated with chlorine which does not help 
the taste of coffee or anything else for that matter.  I run my water 
through a Pur charcoal filter that removes the taste of chlorine and 
many other impurities, but not all.  It would be rather expensive to 
brew with distilled water unless you have a still, in which case you are 
probably contaminating the water with impurities from the plumbing.
