Why Filtered Water Matters When Brewing Coffee
Coffee is 98% water, which means the quality of your water plays a huge role in the taste of your brew. While it might be tempting to use tap water straight from the sink, unfiltered water can introduce unwanted elements that impact flavor, extraction, and even the longevity of your coffee equipment. Here’s why filtered or purified water is a game-changer for your coffee experience.
The Impact of Water on Coffee Flavor
Water is more than just a liquid medium for brewing—it’s a solvent that extracts the rich flavors and aromatic oils from your coffee grounds. If your water contains chlorine, minerals, or other impurities, it can distort the natural taste of your coffee. Hard water, which is high in calcium and magnesium, can lead to over-extraction and a bitter cup, while soft water may under-extract, resulting in a flat or weak flavor. Using filtered or purified water ensures that nothing interferes with the delicate balance of flavors in your beans.
Better Extraction for a Smoother Cup
The right water composition helps extract coffee’s complex notes evenly, bringing out sweetness, acidity, and body in harmony. Many coffee professionals recommend water with a balanced mineral content—neither too hard nor too soft—to optimize extraction and enhance the natural flavors of the beans. If you've ever had a cup of coffee that tasted off despite using high-quality beans, your water might be the culprit.
Protecting Your Coffee Equipment
Mineral buildup from unfiltered water can cause scaling inside your coffee maker or espresso machine, leading to clogs, inconsistent brewing, and expensive repairs. Hard water deposits can reduce your equipment’s lifespan and require frequent descaling. By using filtered or purified water, you not only improve your coffee’s taste but also help maintain your brewing equipment in peak condition.
The Best Water for Brewing
For the best results, use filtered water that removes chlorine, sediment, and excess minerals while retaining a balanced amount of essential minerals for extraction. A good rule of thumb is to use water that tastes clean and fresh on its own—if your water tastes bad, your coffee will too. Investing in a water filter or using bottled spring water can make a noticeable difference in the clarity and complexity of your brew.
