Water Quality

Despite being the major component of every coffee shot, the role of water in achieving the perfect shot is not often considered.

Not only will the quality of water affect the taste, body and aroma of your coffee, it can have a detrimental effect on your equipment.

In the last issue (25), Chris Short discussed descaling and water quality. Reverse Osmosis (RO) technology is now leading the battle in combating water quality and the impurities that cause water scale.

Water scale is by far the biggest offender; it doesn’t discriminate between high end and low end equipment and can destroy elements, pumps, affect machine calibration and force your expensive equipment into early retirement. All of this for the café owner means down time, loss of income and expensive repair bills. Many water filter systems on the market attempt to address the smell and taste of water, but very few deal with the root cause – dissolved solids. These are materials that have dissolved into the water which can pass through standard filtration systems and then precipitate out inside your machine, clogging jets and damaging equipment.

The Genesis series of water filters by Pure Coffee Australia tackles this problem, by stripping everything out of the water through reverse osmosis. This is the same technology that is used to desalinate seawater into fresh water. Once the water is stripped of all its contaminates, it is re-mineralised just enough to ensure proper machine function, without causing damage* to your precious equipment. Not only does it protect your equipment, but because the water is so clean and pure, it brings out the subtle nuances in your blend that are often hard to distinguish. So as well as reducing your maintenance costs, it will reduce your operating costs at only 1/2c per litre in cartridges.

Here’s what some users of the Genesis systems have to say:

Great espresso is only as good as the water used to make it. Everyone pores over their coffee beans, their roasting, their equipment and their extraction, and too few focus on the biggest factor of all: water quality! Damien’s water system removes the uncertainty of inconsistent water and eliminates this as an issue of concern in regard to espresso quality. It frees espresso lovers to concentrate on other areas under their influence. Without fixing water quality, you can never fix your espresso – Instaurator.

Damien has revolutionised RO water systems, making them accessible and specific to all the requirements of coffee roastery and espresso bar needs – Paul Bassett.

Our coffee bar is very fast paced, and the unit has never failed to produce enough water for us. In regards to the taste of our coffee, we have never looked back; there is much more clarity in our espresso, and for us clarity of flavour is a prized element in a cup of White Horse coffee – Matt, Whitehorse Coffee.
