Here’s a party trick: Fill three identical glasses—one with tap, one with distilled, one with RO water. Ask friends to rank them. Most people pick RO as the best, tap as “acceptable,” and distilled as “weirdly empty.” Why? Because our tongues are wired to expect a tiny mineral crunch. Distilled water feels like a lie.
Also, in the world of cocktails, RO water is the bartender’s secret weapon. The clarity of ice cubes matters, and RO cubes are crystal-clear with no weird aftertaste. Your next Negroni? Thank the filter.
