A cup of filter coffee is 98% water. It doesn’t surprise anyone that water is important in making a great brew — but it does surprise people just how big an impact it has.

A cup of coffee that didn’t taste as good as it should have sparked this journey. Founder Maxwell Colonna-Dashwood just couldn’t get this particular coffee to taste good in his shop. The coffee tasted great at the roastery that supplied it, but wasn’t right in the shop, using the same equipment and recipes. Christopher H. Hendon, a regular at the café and chemist at a local university, was in the shop at the time.

This was in 2013. When Maxwell raised the issue with Chris, they wondered if it could be the different waters between the roastery and the shop, allowing different coffees to taste better or worse in seemingly similar environments. They began a journey to study the impact of water on coffee’s flavour. The collaboration gained traction and resulted in a published academic paper and the co-authoring of Water For Coffee — a book that delves into the science and practicalities of water’s impact on coffee.

How it works

Water hardness has a dramatic effect on the flavour of coffee. This effect is difficult to predict, as tap water varies greatly from city to city. Your favourite cafe knows this and uses complex filtration systems to control and customise their water.

Peak Water is the world's first adjustable water filter jug, allowing you to create café-quality water at home — anywhere in the world. 
The unique design utilises a gravity-fed bypass with variable settings, allowing you to decide how many of the minerals in your water are filtered out or retained.


The Peak Water filter utilises a two-chamber design. The main chamber makes use of premium dual-ion resins that have the capacity to completely remove the minerals from your water. However, you want a small amount of hardness to get the best out of a coffee.

The secondary bypass chamber contains carbon only, which combats any unwanted organic compounds, but allows a desired amount of positive minerals like calcium and magnesium to pass through and re-join the newly softened water from the main chamber.
