Why is it important that coffee is 98% water?

Water makes up a significant majority of coffee, which is why its quality is paramount. The composition of the water used in brewing can greatly influence the extraction of flavors from the coffee grounds. This means that impurities or variations in mineral content can lead to undesirable flavors or balance in the coffee. For instance, water that is too hard or too soft can result in imbalance, altering how well the coffee's natural flavors are expressed. High-quality water can enhance the overall taste of the coffee, allowing the nuances of its flavor profile to shine through.

Other aspects of water, such as pH and temperature, also play a critical role in extraction, yet the fundamental point remains that the quality of water directly affects the resulting taste of the coffee brewed. This is crucial to consider for baristas and coffee enthusiasts alike when preparing the perfect cup.
