Peak Water Jug

The world’s first adjustable gravity-fed water filter designed specifically to optimise brewing water for coffee making.

You could say it was a ‘watershed’ moment for the coffee industry when three-time UK barista champion Maxwell Colonna-Dashwood and PhD chemist Christopher Hendon co-wrote the book ‘Water for Coffee’ in 2015. The book highlighted the very real effect of water quality on the result in the cup.

Lively discussions abounded both at professional specialty coffee events and online, culminating in a sort watery milestone last week when a dedicated water forum was established as part of the influential online community The book also set the stage for a variety of water treatment products, like Aquiem and Third Wave Water, which have since emerged to help people manage this fundamental variable more effectively.

Now Colonna-Dashwood and Hendon have returned to make another splash (as it were), with their Peak Water jug offering. Drawing on their knowledge and the perspectives originally offered in the book, they have created a handy, cost effective household-style filter pitcher which aims to transform regular tap water into something closer to ideal for brewing coffee.

Preparing the Filter

To prepare the filter cartridge, soak the filter in tap water for 10 minutes.

NOTE: This soaking process should be completed with every new Peak Water Filter Cartridge.

Test your Tap Water & Recommended Settings
  1. Run your cold tap for a few seconds and take a sample of 200ml (a small glass of water).
  2. Remove a Test Strip from its packaging and submerge in the water for 5 seconds.
  3. Remove and hold for 10 seconds. The yellow tab should now have changed colour.
  4. Compare your results with the chart (below) and move the Peak Water dial to our recommended setting.

Replacing a Used Filter

When your Filter has come to the end of its life, you will need to remove and replace it with a fresh one. Here’s how:

Simply hold the dial in the RELEASE position, remove the Lid and use the ring pull to lift the Filter up and out of the Liner.

NOTE: Remember to prime each new Filter Cartridge, as outlined above.
