If you’re serious about your coffee, you already know that water quality makes a big difference in the final cup. This is especially true when using high-end espresso machines, where even small mineral imbalances can impact both taste and machine health. That's where Shark Tank coffee water enters the scene.
Why Water Quality Matters for Coffee and Espresso
Water makes up about 98% of your coffee. That means the minerals, pH level, and purity of the water you use can dramatically affect how your coffee tastes. Espresso machines, in particular, are sensitive to mineral content. Too much can lead to scale buildup, while too little can result in flat, lifeless coffee.
Is Distilled Water Good for Espresso Machines?
You might think distilled water for coffee is the best choice because it’s pure. While it’s true that distilled water contains no minerals or impurities, it can actually be harmful to some espresso machines—especially those with metal parts or sensors that rely on conductivity. In fact, some manufacturers warn against using distilled water in espresso machines for this reason.
