I once destroyed a perfectly good espresso machine because I was too lazy to buy distilled water. The inside looked like a miniature limestone cave. My espresso started tasting like regret and geological history.
Appliances are snobs when it comes to water. They want the pure stuff because any mineral buildup is basically them getting clogged with tiny rocks. Distilled water keeps your coffee maker humming and your humidifier from looking like a fossil.
My car’s battery even asks for distilled water. Imagine a battery being pickier than you are at a brunch buffet. But it makes sense—impurities can short-circuit things, and nobody wants a car that throws a tantrum on a cold morning.
Can You Actually Drink the Stuff?
Sure, you can drink distilled water. It won’t hurt you. But it tastes like the spiritual void of a hotel swimming pool—flat, lonely, and a little bit disappointed in you.
People joke that drinking it is like licking a clean window. It’s wet, but it’s not refreshing. Your taste buds are so used to the tiny mineral flavors in tap water that pure H₂O feels almost offensive in its neutrality.
I once drank a full glass on a dare. It was fine. Then I immediately craved a slice of bread because my mouth felt like it needed something to hold onto. Don’t expect a flavor party, is what I’m saying.
