How to make your own Brew Water

How to make your own Brew Water

Water, who knew that you could make your own. Well sort of lol. We explain the best way to make your own. And yes we have heard of third wave water and peak water jugs but we love ourselves a bit of DIY. 

When you really boil it down (see what we did there) water makes up 98% of your coffee - that is if your drinking black or filter.


Water Recipe:


  • Scales (down to 0.1 accuracy)
  • 2 x 500 ml glass water containers, with lids
  • Small bowl
  • Baking Soda (not baking powder)
  • Epsom Salts (magnesium sulfate)
  • 1 -2 L Distilled or Deionised water (don’t panic about the ‘not for drinking warnings)


Using your scales measure out the following

  • 8.6 g Baking Soda
  • 25 g Epsom Salts

Pour 500 ml of distilled water into one of your empty bottles. Then add your measured out ingredients.

Shake the concentrate until all of the salts and baking soda have dissolved. It may take a few hours for your salts to completely dissolve, so don’t panic!

Once all is dissolved you have made your concentrate


In your other empty glass jar, add 500 ml of distilled water.

Place this vessel onto your scales and tare.

Slowly and accurately pour 2 g of your concentrate made in step one into the 500 ml of distilled water.

You have now made your brewing water. Boil it and you’re ready to make the most delicious brew ever!

You can save the concentrate made in step one for later use. Ensure it’s well sealed!
