A sense of flatness like a pane of glass. Distilled and doped with O4 this water is flat and broad, coating the tongue to the edges of the mouth. Sea salt makes it more filling and re-energizing. A strong taste of pencils shavings and graphite, and a touch of bitter but smoothing steel, and a satiny mouthfeel. A recycled bottle. A balanced pH. I don’t think the oxygen does anything other than make taste more like flat club soda, which is not ideal. Best to drink tap.
