Tap water / filtered water

Tabby McTat

I see that filtered water is recommended for making a brew rather than tap water. Does anyone know if it makes much of a difference? Or are we talking about marginal improvements...

Dublin tap water is soft and considered some of the best for espresso, no need for bottled... Not sure whether that is true of French Press or Filter...

Good to know. Nice one!

If lime doesn't build up on your kettle and your water tastes fine at room temperatueebthen you're grand.

I use a BWT jug with filters but only because we get our water from the Leixlip plant and I've used a couple of those test kits and our water's a wee bit hard (small bit of scale on kettles etc), so mostly just to convince myself that I don't need to do a full descale or the espresso machine that often.

Taste is pretty negligible to be honest. James Hoffman and a few others say that water plays a huge part in terms of brews, but I'm not sure if that's just because a lot of England etc have extremely hard water supplies compared to here.

I use a Britta filter as the water isn't suitable for filter in Dublin. It tastes a bit gross coming from the tap which I do feel makes a difference.. I've heard of people adding minerals to water too which Is probably a step too far for me.

We had a boil notice here years ago and used get a smell of chemicals in the water for a time after so we started using a Britta filter which I've continued with for coffee. I find the cheap Amazon filters produce nicer water than the expensive Britta Maxtra ones but our water is pretty good now and not hard.

it depends on where in dublin you are, there are at least three different supply lines into DCC and the water profiles are different in each

you are probably on the same supply as me then, which has always been full of bicarbonates, and chlorine.

Depends where you're living and what your water is like.


It's not just about taste.


If the water is very bad it can cause build up in machines too which means you'll have to clean them much more often

You can check on Irish water:

https://www.water.ie/water-supply/water-quality/water-hardness/

Enter your Eircode.

For me it gives 68 mg/l of Calcium which it says is soft. It says anything below 100mg is soft.

The WHO however has a different definition:

Water containing calcium carbonate at concentrations below 60 mg/l is generally considered as soft; 60–120 mg/l, moderately hard; 120–180 mg/l, hard; and more than 180 mg/l, very hard (McGowan, 2000).

I use a Britta filter for my coffee, not sure how much difference it makes but I haven't had any issues with the espresso machine since I started doing this, where I was having issues previously. I have a machine that is pretty difficult to descale so this is worth it for me.

Shows 73 for me.


I mostly use bottled water but I hadn't checked this previously

we're on the navan road, i find the water very hard- goes through kettles, shower head, has a shiny buildup on tea, leaves hair/skin oily

filter everything we drink/cook with these days and it makes a big difference to taste, cleans that film off the surface of the tea nicely, etc

those readings from the website are not to be taken as absolutes

they are a snapshot of a sample

what is especially noticeable is the amount of chlorine, after a spate of bad weather the chlorine gets ramped up for example.

There are many samples though not just one. You can check all sorts of things, not just hardness.

For chlorine I can see 126 tests this year and of those 5 had a reading of above recommended levels.
