  • Mixing (Perth) tap water with distilled water

    I've been doing lots of research on this and it seems the best /taste /cost way to do this for my low usage (4 espressos /wk) is to mix tap and distilled water.

    I'm planning to dilute it till I get a TDS between 50-70. What do you people think?

      All of Perth water is very bad for espresso machines.

      Average tds is around 300! https://www.watercorporation.com.au/...eport-2017.pdf

        Hi.

        I'm distilling water in my house and I then pass it through brita filter. The taste is sweet water that is amazing.

        I then reminerlise using ConcenTrace mineral drops that has hight magnesium contents.

          Impressed..... when I read some of these posts I really wonder if I'm taking my hobby seriously enough.

          Cheers

            Why are you passing distilled water through a resin bed?

              if you already have distilled water, you can go buy some epsom salts and bicarb and make concentrates for mineralisation.

              recipe 7 seems to be geared towards espresso.

                The brita filter (carbon filter) improves the taste of the water in a noticeable way.

                The distiller I have is a cheap one and doesn't get rid of VOC (volatile organic compounds) well enough, this means that the water has some very minor after taste that will go away with time, but the brita filter does the overall finish quite quickly.

                We use it as drinking water. Hence I reminerlise it.

                Obviously, no scaling issues whatsoever.

                The gunk that is left in the distiller is very smelly and looks bad. Fluoride and chlorine smell.

                I live in Sydney.

                  OK, carbon I understand.

                  You and I will have to agree to disagree on remineralisation.

                    Care to explain yourself? I don't claim to be right, but I don't think I had a conversation where we had a disagreement.

                    I'm more than happy to learn and open for constructive feedback.

                      I made too general a statement, I specifically meant the remineralisation of drinking water, which is not what we were discussing on a coffee forum.

                        I was of the understanding that Perth water was getting softer. With the bringing online of the desalination plants (their output is stored in out hills dams), and pretty sure our dams are quite a bit fuller than has been the case several years ago, so reducing the need to draw groundwater that is quite hard.
                        I also think the southern suburbs have softer water than the northern suburbs.
