Hehe BDV. I'm experimenting adding a fraction of my distilled water in my drinking glass, blend with normal water. It is fun how it changes the taste. I'm at like 10% distilled water and the taste really fades away from average to fine. My drinking water has a ph >7.5, so I think I'm neutralizing it a bit, it is strongly charged in minerals, so it brings balance to the taste. I'm really having fun on this, with PH meter, scale, waiting for an EC meter.
Drinking distilled water straight can be dangerous as is it a strong solvent for minerals, you risk to demineralize yourself
You actually can brew your own water mixture to match your personal preferences. Water can have a lot of different tastes
The crap you talking about must be a special mineral blend, like the one they use in factories to make certain bottled brands, they neutralize (osmosis) their intake to obtain a neutral taste, then they add specific minerals optimized to match consumer's taste.
Distilled water seems to have infinite application, and exceeds all my expectations. Mixed with the cranberry solution, and warm, it seems like it is removing the whole harshness. Amazingly smooth. I breathe like a new born
