The competition was organized by the industry organization Svenskt Vatten.

- Our Swedish tap water is in many ways a unique product, with home delivery to every home and workplace - everywhere we need water.

Always locally produced, always fresh.

Tap water is our most important food - but also something we take for granted.

We need to protect this natural resource and the infrastructure that makes it possible, says Pär Dalhielm who is CEO of Svenskt Vatten in a press release.

To Mjölby's consolation, according to the jury, it was difficult to choose this year's winner.

- I'm sure we tried Sweden's 20 tastiest tap water today, all perfect thirst quenches.

The final test was a challenge, the differences are incredibly subtle even if the jury agrees on who is the winner.

This year's winning water has that little extra that makes you want to take many, big sips of it, says Gunilla Hultgren Karell.
