I often drink vitamin and oxygen enhanced water so I thought I'd try this water due to the trace minerals. This was difficult for me to drink, the flavor is not water like and while it doesn't taste dirty or gritty, it's a mental thing. The water is very very black almost like a strong dark coffee. I'd strongly suggest trying a single serving before buying an entire case because out of 4 people in my family no one really liked it,...that leaves 20 bottles.
