Answer about buffering: Evian's buffering comes from bicarbonate, I believe. Elete's buffering comes from chloride. There is a very high % of chloride in Elete.

Now, the article I linked-to earlier, which presented a recipe for mineralized "fairy" water, looks like the author got it wrong. First of all, the author assumed--wrongly--that good tasting water was good for coffee. Second, the author's own recipe is over-the-top composed of buffering compounds, including bicarbonates and chlorides, which, according to Maxwell, will guarantee flavor neutralization. Third, the author assumes that TDS is all that matters, which Maxwell pretty well argues against. Ok, to be fair, the author does seem skeptical about what was really going into the water SCAA was using.

This buffering thing is a revelation. I always felt there wasn't much difference between my 30 ppm TDS filtered water and a bottle of Fiji water. Of course, I am using a Trifecta, which means some added pressure is involved. That could have an effect on the outcome. Or not.

To be continued after I try out the Elete solution myself.

This is one approach, although not particularly cheap:

Hey Andy.
I purchased it, it works, and IMO is not really that expensive when purchased in the little bottles with the syringes.
That said, Costco carries a delicious spring water that measures pretty low according to my KH GH test kit. The kit is MUST to own, IMO.
I then add a great under-sink system I just installed a while back, called 'ThePurestOne." The water is also delicious, but measures 120 with my generic TDS meter. GH is like 112, KH about 80, as memory serves. Combined, the water is a about 7.25 PH and delicious.

I suggest to the OP get a good under-sink for flavor, and blend with RO 50%. If it still tastes flat, add a bit less RO. Don't worry about a softener.




EDIT: the spring water from Costco is Christal Springs, comes 6 One gallon plastic jugs to the box. Fairly priced.

Rob, that water filter is the most innovative and appealing design I've ever seen for the home. If I had known about it three or four years ago, I would have chosen it rather than the ion exchange filter I ended up buying. I like its simplicity and great cost effectiveness.

Well, now I can say that dewmaster07 should not be too eager to find a high TDS bottled mineral water. The problem discussed in the video linked by yakster is the presence of buffering in addition to the hardness solids. The speaker, Maxwell Colonna-Dashwood, says that just about all natural mineral waters will have way too much buffering, which will neutralize all the acids, making the coffee taste flat.

I too found a few sites which claimed that Alpine Geyser water was too hard for espresso machines and caused a lot of scale.  I must say that in trying this water for the first time yesterday it did create the best cup of espresso out of my machine to date.  It did not taste flat; it was a great needed improvment.

Unfortunately, I have a feeling that Elete will prove to be too heavy on the buffering side, as it is way salt-heavy, compared to hardness molecules.

What about the many mineral additive products available on amazon which are supposed to be added to RO/Distilled water?

The truth of the matter is that the Global Customized Water formula is the only solution that was

a) designed to specifically address coffee flavor

b) vetted (I believe) by tasters at SCAA

I've been trying to get in contact with those guys ever since I saw the link. I don't think they have much interest in selling their formula in small bottles to consumers. I'm trying to see if they have interest in working out a more compact add-on solution for existing purifying systems.

Andrew, can you provide a few links? The only mineral additive liquids or powders I've seen had ingredients that would interfere with the flavor or muck-up the body of the brew. These were all electrolyte solutions.

The first one has a lot of vegetative matter--and castor oil. Of all of those, I think the Concentrace looks like it has the best blend of magnesium and minimal chloride buffering. It certainly looks better than Elete. But it still doesn't contain any calcium.

More on over-buffering. Evian has close to a 1-to-3 ratio of flavor-extracting hardness molecules (calcium + magnesium) to flavor-killing buffering molecules (bicarbonate). Concentrace has approx. the same ratio, except it contains chloride as the buffer. Evian is supposed to suck as a water for brewing because of its high buffering content. If chloride is as effective as bicarbonate for buffering acid, then I would expect Concentrace to suck as well. Elete is far worse in this respect.
