Coffee water optimisation is one of the most impactful, yet overlooked, elements in brewing better coffee.

Water makes up most of every cup of coffee, and its composition — minerals, hardness, alkalinity — has a direct effect on extraction, flavour clarity, acidity, balance, and mouthfeel. Water that’s too hard, too soft, or chemically unbalanced can mute sweetness, exaggerate bitterness, or flatten the acidity in beans that should taste bright and nuanced.

This collection brings together tools and solutions for coffee water optimisation — from filter jugs that remove unwanted substances to mineral blends and measurement tools that let you dial in a repeatable profile. Whether you’re filtering tap water to reduce scale and impurities or building your own profile with mineral additives and a TDS meter, this is where you find the gear that helps you understand and control your water.

At Nordic Brew Lab, we use water optimisation techniques every day behind the bar, because even the best beans and equipment can’t compensate for poor water quality. The right balance of calcium, magnesium, sodium, and bicarbonates supports consistent extraction, highlights desirable flavour notes, and lets the coffee express itself properly in the cup.

Products in this collection include mineral concentrates for tailored profiles, water filters and cartridges to reduce hardness and contaminants, TDS pens for measuring dissolved solids, and systems that let you build water profiles with precision. Whatever your setup — home brewer or professional — investing in coffee water optimisation gives you control over a variable that’s fundamental to great coffee.
