Water, Water Everywhere

I've been tasting the different brands of distilled water produced locally and elsewhere. I've also tasted Superstore's filtered water.

I have a few comments that relate to this...

1. I like the un-taste of Alpine Distilled Water, which is produced right here in Winnipeg.
2. I also like the taste of another brand of distilled water, by ....
3. Superstore's 6-stage RO (Reverse Osmosis) water is tasty, almost distilled-like, if it isn't.
4. Life brand (Shopper's Drug Mart) Distilled Water. Tastes great. But... from the Winnipeg perspective it's trucked 2000 kms to get here from southern Ontario. Not a good thing for the environment. If I was living in metropolitan Toronto this wouldn't be an issue. One thing I like about the Life Brand water is that it creates ice spikes when you make ice cubes from it - meaning the water is the purest you can find.
   

There are a few other waters that I'm questioning though, because I've had a bad jug or whatnot:

1. World of Water DewDrop Distilled Water. I bought a gallon of it this past week and it definitely had an aftertaste to it. Sort of aluminum metallic. I'll give it another try and see if it's any better.
2. Pepsi's Aquafina brand of "pure" "demineralized" water. I sensed beforehand that this is probably just like "spring" water, like Coke-Cola's Dasani. The bottle I bought was from SDM and it had the taste of plastic. I took two sips and threw the rest away.
