Want to use the perfect water to brew your coffee? You will finally find out how.
By combining Zerowater with the Dark Roast Profile you are optimised for medium roast coffees. Our profiles are recommended for both traditional drip coffee brewers (Keurig, Mr. Coffee, etc.) as well as any manual brewing method (AeroPress, chemex, V60, etc.) This water profile helps to reduce bitterness provide while preserving chocolate and nutty characteristics in your dark roasted coffees.
All our profiles are made using the Specialty Coffee Association’s (SCA) guidelines for improved flavour for coffee.
- Optimized for Dark Roast Coffees – Perfectly balanced to smooth out harsh bitterness while enhancing the full-bodied, smoky, and nutty flavors of dark roast coffee.
- Ideal for All Brewing Methods – Works seamlessly with automatic coffee makers (Keurig, Mr. Coffee, Breville, etc.) and manual brewing techniques(AeroPress, Chemex, V60, Hario, Kalita Wave, French Press, etc.).
- Reduces Bitterness & Enhances Sweetness – Designed to soften acidity and bitterness while bringing out caramelized sugars and bold espresso-like depth.

If you do not use Zerowater you can also add one stick to distilled or RO (reverse osmosis) water. All it takes is a little shake, and you are ready to brew your favourite coffee. Your coffee has never tasted so good!
Dark Roast Profile comes in 3 sizes:
- 12 sticks of 1 Gallon (3,8 litres) – makes 12 gallons (45,6 litres) total
- 12 sticks of 5 Gallon (19 litres) – makes 60 gallons (228 litres) total
- 20 sticks of 2 Liter – makes 40 liters total – some people prefer half the minerals so this is a good choice for ‘softer’ water to add to 1 gallon (3,8 litres) of water. Experiment to discover your preferences today.
