Well I guess you never drank genuine spring water as I did in the past.
The source of spring water I had was never commercial. It was from a mountain spring water and it wasn't easily accessible and people weren't allowed to fill more than one 500mL bottle of spring water for one person per week. The water was bluish in color and one sip or small gulp from it would cut immediately the thirst or need for water.
I have a friend here in the city who bought a vortex energizer for whole house and I drank the resulting water and it's very very close to the quality of spring water. Way much better than the quality of regular filtered tap water.
I find the taste of distilled water pretty nasty for myself no matter what source.
