Looking for the perfect water to brew your coffee? You finally found it. Filtered water or even great tasting water can flatten your coffee and won't help your coffee taste amazing. The science behind brewing coffee is complicated and requires the right minerals, water buffer and more to create that perfect cup of coffee. Protect your mornings, coffee gear and favourite freshly roasted coffee for only cents a cup with Third Wave Water minerals. Just add one Third Wave Water sachet to 2 litres of distilled or RO water, shake, and use to brew your favourite coffee. Each pack contains 20 sticks - making a total of 40 litres (at the default ratio). Adam's Tip: Our favourite way to use TWW at the roastery and home is to use the Espresso Profile (yes, even for filter coffee) but dilute it to half strength (so one sachet for 4L of water instead of 2L). We find this provides the best balance of total hardness and buffer to help our coffees really shine :) Classic Profile Perfect for brewing light to medium roast coffees using most brew methods.
