Can I Use Filtered Water Instead of Distilled Waterに関する専門家の意見を詳しく解説いたします。

If you’re making coffee or tea, here’s where it gets hilarious. Coffee experts swear that distilled water makes a flat, lifeless cup because it needs those minerals to extract flavor properly. But too many minerals (hard water) also makes bitter coffee. So filtered water hits a Goldilocks zone—it’s the comedy club open-mic night of brewing. One study found that water with 150 ppm calcium makes coffee taste weaker, while water with 50 ppm calcium tastes fruity and bright. Distilled water is 0 ppm, so your morning joe tastes like a wet cardboard envelope.
