Bottled water and distilled water are as similar as a golden retriever and a cat that’s plotting world domination. They both come from a faucet or a spring, but what happens next is where the drama begins. Distilled water has been violently boiled into steam, then cooled back into liquid, leaving behind every mineral, contaminant, and existential crisis.
Meanwhile, bottled water is often just tap water that got a fancy haircut and a marketing budget. Some brands filter it, some add minerals for “taste,” and others literally take it from a spring and slap a “glacier-fed” sticker on it. Distilled water, on the other hand, is so pure it’s basically the water equivalent of a monk who’s taken a vow of silence.
Why Your Coffee Maker Hates Distilled Water
Here’s a surprising fact: distilled water is aggressively pure, meaning it has no minerals like calcium or magnesium. That sounds great, right? Wrong. Pure water is actually a thirsty little gremlin that wants to steal minerals from anything it touches. Drink it long-term, and it can leach minerals from your body, which is why astronauts don’t guzzle it on the regular.
But bottled water? It’s like the friendly neighbor who brings over a casserole. It usually has a balanced mineral profile, which is why your coffee maker and your kidneys don’t stage a rebellion when you use it. Distilled water, if you put it in a coffee maker, will slowly corrode the metal parts because it’s too busy being a chemical widow-maker.
