You buy premium beans, own a top-tier grinder, and use a precise scale—so why does your coffee still taste flat? The culprit is likely coming straight from your kitchen sink. A cup of coffee is roughly 98% water, meaning the quality of your water dictates the quality of your brew.
Hard water packed with heavy minerals prevents the water from properly absorbing the flavorful soluble compounds in coffee. On the flip side, highly distilled or reverse-osmosis water lacks the essential minerals needed to pull out those flavors, leaving you with a dull cup. For the best results, use a simple carbon-filter pitcher (like a Brita) to achieve the perfect balance.
