ELI5: Does drinking water actually have a flavor?

So many of my friends complain about tap water 'tasting' different to bottled water and that VOSS water is the best bottled water to drink because it tastes great.. What the hell it all tastes the same right? Can someone clear this up for me please ELI5!

If they were all pure H2O, they would taste the same. However, water from different sources have different chemicals and minerals in them - it's not "just" water by a long shot. Different bottlers, different municipalities and other water sources all have different kinds and amounts of impurities that affect the taste of water.
