Ever wonder why your coffee at home tastes flat compared to the fancy café? Ppm is your culprit. Specialty coffee nerds swear by water with a ppm between 100 and 150. Too low, and your coffee tastes sour and thin. Too high, and it gets bitter and muddy.
So if you’re serious about your morning caffeine, check your water’s ppm. Or don’t—and just blame the barista. (We all do that anyway.)

And no, you don’t need to memorize a number. Just remember: under 100 ppm is spa water for rich people. 100-300 ppm is normal, happy water. 300-500 ppm is getting crunchy. Anything over 500? You might want to think about a filter unless you enjoy chewing your water.
A little exaggeration, because why not?
If your water had a ppm of 10,000, you could probably walk on it. It would be less water and more a liquid sidewalk. I’m being dramatic, but only a little. Seawater is about 35,000 ppm, and trust me, you don’t want to chug that unless you’ve been lost at sea for three days.
So next time someone says, “What’s the ppm of your water?” you can casually reply, “Around 150, like a good espresso shot.” They’ll be impressed. Or confused. Either way, you win.
And if someone gives you a weird look, just shrug and say, “It’s just water, but measured.” Then sip your glass with the confidence of a person who now knows what ppm actually means. Cheers to that. Now go test your tap water—I dare you.
