Let me first start by saying, I don't have an 'ology' and therefore I am not a scientist. Secondly, make yourself a coffee - you'll need it. I am vaguely hopeful that someone might stumble over this after I have been given the answer I am looking for and it might work for them too. Maybe they feel as clueless as I do despite my best efforts! What I am is a bloke who, when he turns on the tap, can smell the chloride in his water. Other times the water looks very cloudy. I like the taste of my water to drink and enjoy the coffee I drink for the most part. On this everlasting journey of coffee discovery, I am slowly trying to improve all aspects of my coffee making by honing my skills, purchasing better equipment, better coffee and now - investing in better water. Importantly, as I scrape together enough pennies to buy a better machine than my £30 off gumtree Gaggia New Baby, I want to make sure the water I will use will give me the best tasting cup and do the least harm to my new machine. Given this machine is months off, I figure I have the time now to find what works best from a water point of view. I brew with a moka pot, Aeropress, V60, French press and the Gaggia and intend to use the same water for all methods. I bet there is someone wonderful out there that changes their water for each method right? I've watched a few videos, read the relevant bits of both of Hoffman's books, read numerous posts on ~~various coffee forums~~ this very fine forum and all in all I am perplexed. The key for me is to find a relatively inexpensive method to get the best possible water. By inexpensive, I mean that I am not installing new taps, water filtration devices etc. to my mains water supply. A Brita type filter, Zero Water filter to which I then supplement the water with…..er, supplements or some kind of recipe water could work I *guess* but I assume RO filtered water is out of my price range. Blimey this is going on isn't it? You're going to ask about my water aren't you? Well, here is the Northumbrian Water Report for my postcode: ![](blob:https://coffeetime.freeflarum.com/32557fb1-a5f2-4cf7-bd52-13eb18e46bf3) The water in my area apparently ranges from moderately soft to slightly hard. When I look at the numbers and compare to Hoffman, I think I am right in saying my Calcium Carbonate levels are in roughly the right place, the Calcium is ok, it's super alkaline and Sodium is high. I don't want to be a Hoffman fan boy and I am happy to be led but struggle to wade (pun intended) through lots of information about what is "right" and his information is so accessible. The answer may be as simple as buy a Brita and see what you think. Or that and BTW and compare. Or Zero Water and a few sachets and try them and see which you like best. If that's the case, I'll be back to ask where to get these things cheaper than from the supermarket! If you've got this far and have the will to engage further - you have my thanks in advance.

Well in expensive and a counter top generally don't go hand in hand, The cheapest option is rodi setup, £60-80 will last a year or two. But it means adding under a sink or in a garage if you have space There are other options but I've not used them.

@"JesmondJester"#p40064 Bottled water with the right composition is an option, depending on how much you think you will use. The link doesn't work correctly for me?

I’ve got what I suppose a lot of people would say is an expensive (yes, yes, overpriced) machine. I use Waitrose Lockhills. It isn’t perfect but it’s cheap, quick, zero faff, and if/when it becomes an issue I’ll worry about it then. Take from that what you will!

> @"Ernie1"#p40073 I use Waitrose Lockhills. > > It isn’t perfect but it’s cheap, quick, zero faff, and if/when it becomes an issue I’ll worry about it then. I have exactly the same attitude to Tesco's Ashbeck.

@"Rob666"#p40074 Lockhills is the same water as Ashbeck.

Or that and BTW and compare. Or Zero Water and a few sachets and try them and see which you like best. I don't recall Hoffmann having any information about water. You don't need any sachets of anything with the Zero jug. See if you can get an alkalinity reading (in mg/L CaCO3) from your water supplier. You know the Zero jug water will be 0, so mix your water to get around 50g/L alkalinity. So say your water is 150mg/L use 1 part tap to 2 parts Zero jug water, takes moments to mix in a kettle/jug on scales. A KH/Alkalinity drop kit is handy, you could then check results with a BWT jug too. Making coffee is more like cooking than an ology. Easier than a lot of cooking which commonly has more than 2 ingredients 😀

> @"MWJB"#p40075 Lockhills is the same water as Ashbeck Interesting! It wasn’t the same a few years back, but looks like it might have changed since. Is that the case @"MWJB"#139 ?

Sorry guys - I posted what I thought was a picture of the make-up of my water but didn't check the post afterwards. Try this. [URL=https://i.imgur.com/w8H7MG9.png][IMG]https://i.imgur.com/w8H7MG9.png[/IMG][/URL] I'd be fine to run with the bottled water solution. I probably use 600ml a day at the moment. My main concern with this is the plastic bottle waste and collection / storage of them. First world problems.

@"MWJB"#p40076 Thanks! I like the idea of mixing enough in bulk to use over the course of a week and just do the mixing once. The other thing is, mixing with tap water which has such variance in the alkalinity concerns me. I'd love to know I am using the same water every time, for every cup no matter the method of brewing. And it be cheap. And be easy. I don't ask much do I? :-) I cycle a fair amount and there is quote made famous by bike designer Keith Bontrager concerning the manufacture of bikes. "Cheap, light, strong - pick two". I think this is going to be the same. "Cheap, easy, no waste"

Zero filter jug and third wave water sachet for easy, or bicarb for cheap. Both relatively cheap options and replicable. Bicarb a starting point to let you experiment more.

caffeinated-carp I am not dedicated enough for this :) - but I used a basic TDS reader just to see the overall numbers - though I realise thats not showing any detail. I also picked up a dip test from Amazon. Again I believe the drop tests are the best.

I used the dip tests just to see that the output from the Osmio was “working”. Now I just fill and forget.

MattH I’m not sure I’m dedicated enough to be honest! Time will tell if I keep up with this. I feel like a mad scientist…

Get a buiness card, cut a strip 5mm wide measure 5mm from the bottom, make a line and bend into an L shape, to make a little scoop. Scoop from a pot of Bicarb and add to 2 litres of RO water…place in machine and get on with your life.

caffeinated-carp

DavecUK yeh that’s probably easier :D although admittedly whilst this stuff can drive me insane i do enjoy a good process :)

so you’re reckoning that a 5 × 5mm square will result in the right amount of bicarb basically for 2 litres worth?

Bagpu55

caffeinated-carp

I did this, my 5mm x 5mm gives me around 0.1g of bicarb that I use for 1 litre

DavecUK

caffeinated-carp I wrote this article probably 15 years ago now.

http://coffeetimex.wikidot.com/ro-water-copper-corrosion

I used 2 scoops then, but 1 scoop is enough.

caffeinated-carp

Bagpu55 quite a neat trick :)

I timed it last time as was annoyed I needed to top up again and it took me 3-4 mins to put 2l into a jug and weigh in the powders. So not too bad. Not sure the difference in time for using a bit of card vs weighing is much time saved.
But less time refilling the zero jug.

Good to hear that I chose the same recipe and it’s one that is most machine friendly.

caffeinated-carp

DavecUK useful thanks :)
