Some really interesting revelatations about water and coffee.

The comments are really good:

Of course some commenter @karolasvalickas has a water oxygen meter, and has done some testing by brewing with "naturally oxygenated water" i.e. dew water, that was measured at 19.8 mg/l, compared to "naturally spring water" that was 6.8-8 mg/l

And the dew-brewed coffee was reported as "special-state inducing tastes and smells"
