Does water have a taste? Yes. No. Maybe. It depends on your mouth, the temperature, and the rocks it touched.
Water is a shape-shifter. It takes on whatever flavor you bring to the table.
So next time someone says, “Water tastes like nothing,” look them dead in the eye and say, “Not if you’re paying attention.”
Then chug your glass like the water sommelier you were born to be. Cheers.
