Distillation is the bougie, labor-intensive cousin of boiling. You don’t just let the steam fly away into the air like a cheap party trick. Instead, you catch that steam, cool it down, and collect the pure liquid that’s left. This captured vapor is free of minerals, salts, and almost everything else that wasn’t a water molecule.
Imagine you’re a very lazy magic chef. You throw your tap water into a pot, put a lid on it, and then put ice on top of that lid. The steam hits the cold lid, turns back into droplets, and drips down into a clean container. That is distillation in a nutshell. It’s not rocket science, but it’s a far cry from just letting a kettle whistle.
So when you boil water freely, you’re sending the pure water vapor to the clouds while the mineral-heavy liquid gets thicker in the pot. You’re removing the good stuff and keeping the sediments—the exact opposite of what distillation does.

So, What About Your Coffee Machine?
Sarah’s espresso machine was a smart one, honestly. Those fancy machines hate minerals because they gunk up the tiny pipes. If you use boiled tap water, you’re still pouring in calcium and magnesium that will, over time, turn your machine into a slow, sad, calcified rock. Boiled tap water is not distilled water—it’s just pasteurized, mineral-rich water. Your machine will not thank you.
If you absolutely need distilled water for a humidifier, a car battery, or a science experiment, don’t yank that kettle for five minutes. You have three real options: buy it at the store (lazy, effective), get a countertop distiller (expensive, but cool), or collect rainwater (but don’t do that if you live near a highway).
Oh, and one more thing: drinking distilled water is safe, but it tastes flat and can actually strip some electrolytes from your body if you drink only that. Your tap water, with its subtle mineral flavor, is usually the better choice for your health—just make sure it’s safe to drink in your area.
