Adelaide water quality

[yldlj]

Actually I bought Pureau recently from Mal's recommendation because I am getting a bit tired of remineralising my own water, it is a really great tasting water. But I was also concerned if it was just straight RO water. I did some searching on their website it says it is RO'd then filtered and it does have minerals although a very minuscule amount.

"On a parts per million concentration (ppm), Noble’s Pureau still maintains enough mineralisation to be healthy to drink and will not draw minerals or nutrients from people’s bodies."

Of what minerals i'm not sure but it seems to be a secret

From the website. Doesn't seem suitable for espresso machines at all

This is the reason why my next machine will have a copper boiler.

There are some very high quality bottled water options around that contain zero Chlorides, such as the Pureau brand available in most places...

Mal.

This is the second time someone has recommended this water. I just don't understand how it can be good because apparently it has no minerals in it at all.

My reading on this issue indicates that Chlorides (ie Cl-) can only be removed by reverse osmosis or distilling. Chlorides form part of salts. Chlorine and chloramines can be removed by a resin filter system like the Brita Purity Finest filter system - but not chlorides.

Yea this is what i am starting to understand. I had some water tests done and results showed chloride levels were high and was recommended towards a RO system. This is fine as obviously after spending decent $$ on a nice machine i want it to last however we are looking well over $1k for something to deal with the water. So kinda tossing up between bottled water / new filter system. All other things seem reasonable except the chloride so now kinda stuck on this decision..

Water report came back with:
PH 7.1
TDS 157ppm
Chloride 71 ppm
TH 51 ppm

Agree...
Not worth mucking around with various Internet tropes such as 'leaving the water standing in a jug for a couple of hours'. You will end up paying too high a price for non-qualified, regurgitated misinformation.

hi Nate07 Not absolutely sure, but i was of the opinion that standing for 1 day released the chlorine ( thinking tropical fish tank before you add extra water for the fish ) or you can get drops from pool shops and aquarium shops etc that neutralise chlorine or speed up its natural loss. Now chlorides , i think are the byproduct of the chlorine doing its sanitising ( think public pool smell) and unless there has been an awful big demand for chlorine ( think dog in pool or kids doing other things) then there shouldn't be chloride issues in good quality tap water.

In a coffee water scenario- just about all levels of water filters handle chlorine in a reasonable fashion -- but not as many do a good job with ph level/ water hardness which are culprits for scale. Please wait for others to chime in , as i said, i am not certain.

[nate07]

What would be the best way to reduce chlorides in water?

[yldlj]

Yep. I tested the hardness of Mt Franklin bottled water and it was very soft.

[EspressoAdventurer]

Is there any safe bottled water for stainless steel boilers? I was using mt Franklin bottled water previously and while the hardness is very low I'm not sure about the pH as I couldn't find anything online.

Just be aware that any stated 'specs' by a food manufacturer( milk, water etc.) is Indicative Only, and not necessarily what the bottle in your hand contains.
The figures are factually a representation of a 'sample' put forward for testing at some point in time.

[yldlj]

I don't think it would be leeching metals from the boiler.

[AtticusSinclair]

I had, for about a week, a Crem One Dual Boiler that had two copper boilers. The coffee tasted great, but I found the taste of the hot water from the tap borderline undrinkable; tasted incredibly metallic. The machine had done about 300 shots by this point, and the water going in was Adelaide tap water filtered with a Brita Maxtra Limescale+ filter. Perhaps it was lowering the hardness to a point of leaching the metals? Or the machine was just still too new?

I understand that completely pure water can be problematic because the water level sensors in certain boilers require some dissolved solids (ions) in order to function correctly. Also, it seems generally accepted that a certain level of hardness (carbonate) is required in the water to optimize the flavour profile of coffee. This is why users of reverse osmosis systems re-mineralise their water in a variety of ways.
