When it comes to brewing the perfect cup of coffee, most people focus on beans, grinders, and brewing methods. But there’s one element that makes up 98% of your coffee and is often overlooked: water. Whether you’re an espresso aficionado or a pour-over purist, the quality of your water can make or break your brew.
Most tap water contains chlorine, chloramine, heavy metals, or excess minerals. These affect the aroma, extraction, and taste of your coffee:
● Chlorine/Chloramine: Adds a chemical taste and masks coffee’s natural aroma.
● Hard Water (high mineral content): May lead to over-extraction and chalky flavors.
● Soft Water (low mineral content): Can under-extract, leading to weak, flat coffee.
● Contaminants like lead or PFAS: Pose health concerns and introduce off-flavors.
