Water FAQ

Water quality is crucial because it affects the extraction of flavors from coffee beans. Poor water can lead to flat or bitter coffee, while good water enhances aroma and taste.
Hard water, high in minerals, can over-extract coffee and cause limescale buildup in machines. Soft water, low in minerals, may under-extract, leading to weak coffee.
Water filters remove impurities like chlorine and heavy metals, which can affect coffee's taste. They balance the mineral content, ensuring optimal extraction of coffee flavors.
Change your water filter regularly, depending on usage and water hardness. For heavy use or hard water areas, more frequent changes are recommended to maintain coffee quality.
Yes, you can use water testing kits to measure mineral content and pH levels. Compare results with the Specialty Coffee Association’s standards to ensure it falls within the optimal range for coffee brewing.
