I suspect it'll be the one mandated to be sold alongside the other Coca-Cola owned sodas.
The best(?) water I've ever had that wasn't from a tap is the mega cheap Kirkland Signature stuff from Costco. It's still largely the same taste as the tap water, though I am fortunate enough to live in an area with decent tap water.
I'm so happy to see so many comments shitting on Dasani. I've sworn at random times to friends and family that Dasani tastes like garbage. Like wet dog runoff or water that was stewed with pennies. But nobody ever agrees. It actually tastes closer to my sulfur-y well water than any other normal bottled water.
My girlfriend's house has sulfur-laden well water. I find it absolutely revolting, taking a shower feels like I'm in a pot of hard boiled eggs, but she swears she's used to it.
I think it's subconsciously the reason she's always dehydrated.
Oh god, I don't know if I could do that. Our showers are softened and... something else that removes the smell. And we have an under-sink 5-stage filter for drinking or cooking with because if you use the well water for, say, stew or pasta, it just tastes "off"
