Water that is distilled or otherwise purified so as to be perfectly good in a steam iron or a car battery may not be at all suitable for human consumption.

If you can buy a ZeroWater pitcher filter over there, and feed it any low mineral tap or bottled water you would be good to go. Or if you can find a very low mineral (less than around 50 ppm TDS or so) bottled water at an affordable price you could use that as a base.

Posting a new thread with a topic title something like: "Where can I get purified potable water in Italy for coffee recipes." might catch a helpful response.
I've tried using filtering caraffe at homes (for drinking water) and wasn't satisfied.

I can buy low TDS water but it's not cheaper and then the math would get more complicated.

Atm I'm set to call the seller of the bi distiller water I saw online and see what's the deal with the shipping cost, If i can get below 1 € / lt with a 6 x 10 lt jug purchase I'd be pretty good

ZeroWater is a somewhat unique pitcher filter. It does the usual carbon filtration but also uses a mixed bed ion exchange resin to give you de-ionized water, usually 0 - 2 ppm, always less than 6 ppm, which is a good choice for recipes that use distilled or de-ionized. If your water is high in minerals though the filters don't treat much water and they are a little pricy.

And on HB: How pleased are you with ZeroWater solution?

Hello guys, wanted to give updates!

Took me a long time to find suitable distilled water and yasterday i prepared the water for the first time.

The process was harder than imagiend, I hope I can make it easier over time.

I had to slightly tune the recipe since I wanted to end up with 1.030 lt of water in a bottle (aiming for 5x 205-206 pour).

Since I didn't want to up the 2 and 8 gr of solutions cause they were harder to measure, I decided to increase the concentration:

ended up with 0,86 sodium + 103 potassium and 2,53 magnesium.

I tried to aim for perfection but something in the process was a little bit off as I expected, like a 0,01 that i couldn't shake into the bottle to maybe not putting exactly the 2 gr and 8 gr in the 1 lt bottle (drops were stuck etc) but overall I think i was reasonably precise.

Today I did my first brew keeping everything the same (it's a medium roast specialty blend, this is actually my 5th cup so I got to know the coffee a bit) trying to keep everything the same and I noticed a lot of difference in the cup.

It's a little bit brighter and there are definitely more flavours coming around than usual, but I feel like they are not armonized very well.

I get a bit of "saltyness" more as a sensation on the tongue than as a proper taste, an a bit of "lactic" taste that I have experienced in the past as well but not in this coffee (which was primarely nougaty I'd say).

For the trouble I went to, I want more. What do you think should I do to the water recipe? Should I alter my coffee recipe (grinding as well) now that I have a new water?

Tried to grind finder (2 clicks, so 25 micron VBM on my grinder) and everything came togheter a little bit better, but I'm still not getting extra pleasure out of my cofee compared to my old water. bitterness and astringency bits seem to have dulled and that's a plus, but other than that it's not kicking my coffee up a notch

Update 2:

I'm pretty sure I fucked up the first time: I was making another 1,03 lt bottle of water and i noticed 2 things:

1) I'm pullin the concetrated water out of the 2 bottles with a syring, aided by a plastic tube to reach inside it: there's water that remains inside the tube, and I din't pay attention to it the first time, so when I was pulling an release x ml of water read on the syring scale, I'm also adding the ones stuck in the tube. That is the first mistake.

2) I was payin attention at the bottles and the mangesium sulphate one had a lower level compared to the other one, which shouldn't be the case. My first thought is that I put on them the wrong label, but I tasted the content and the bicarbonate one tastes like sodium bicarbonate and the sulphate one tasted strange and unpleasant. I must have switched them while they were still unlabelled!

I'm going to make a try tomorrow and I should see improvements

Last update (if anybody in the future stumble upon this thread).

Much much better now. It doesn't unlock anything "new" but i get good body, extreme persistence with very very little harshness. 10/10 would do it again
