Drew Frohn, a wholesale manager and coffee educator for Coava Coffee Roasters, once told HuffPost that a good cup of coffee starts with water quality. That’s important to know, considering that coffee is 98% water. However, it doesn’t matter how filtered your water is: Over time, your coffee maker can get a layer of limescale (or build up of calcium carbonate) caked onto its insides and parts, whether that’s a brew basket, Keurig, coffee pot, Chemex, Nespresso machine or even your favorite mug. That’s no bueno when you want that perfect cup of Joe, as it’ll affect flavor and your coffee maker’s brew efficiency.
If you’ve been dissatisfied with the quality of your coffee lately, consider the fact that it may not you, the beans, your measurements or water. It could just be your machine’s cleanliness.
Take it from one reviewer who swears Active’s descaler made for a better tasting coffee. “I have had my Keurig for at least 10 years and have NEVER cleaned it EVER (I didn’t know I had to do this lol),” they explain, “and I can definitely say the coffee takes so much better now! It was amazing how much junk came through with this process! Will definitely continue to use monthly now that I know how great coffee should taste.”
