FAQ
How do I use this water?
Just pour it into your kettle or coffee machine, and brew up an unusually delicious cup.
Can I drink this water?
You may drink the water, and most people say it tastes slightly better than normal drinking water with an especially nice mouthfeel. That said, the water truly shines when used to brew coffee.
What's in the water?
Our water consists of purified water and food-grade minerals which occur naturally in glacial and spring mineral waters, in comparable amounts.
Ingredients: Deionized water, sodium bicarbonate, magnesium sulfate, calcium carbonate, magnesium chloride, calcium chloride, potassium bicarbonate.
Will I need to descale?
This water does not build up enough scale to require descaling with normal use.
Can I put it in my coffee maker?
Yes, this water is purpose-built for coffee makers and other filter coffee brewing methods.
When does the water expire?
Unopened cans of water will not expire if kept at cool ambient temperatures.
What makes this different from other water?
It's all in the mineral composition. Each mineral ion plays a different role, as described higher up on this page. By using just the right amount of each ion, we are able to finetune the performance of the water. Furthermore, we dissolve limestone in our water using a special process also described higher up on this page. This allows us to produce silky smooth water that brings out all the sweetness, clarity and aromatics from coffee, with none of the harshness.
Will this make my coffee taste metallic?
Absolutely not. Aluminum cans feature a liner inside, so the water isn't in contact with aluminum.
