    One of the things I have noticed over the years is that the water used to make coffee in Western Europe is clearly different from what we use in Evanston. (I specify Western Europe since I haven't noticed the phenomenon to the same degree in Eastern Europe or Russia.) Since I'm not a professional, I don't know the appropriate word or jargon to describe what I'm experiencing, but I've noticed--as an almost regular thing--that the coffee there is "thicker" or more "syrupy" than here. I'm not sure how much of a change it makes to the actual taste of the coffee, but it's happened so many times, that I've found it impossible not to notice. And so I wonder: is it the hardness of the water (the water in Evanston is from the lake and is hard, without being extremely so)? Is it a particular mineral (or combination)? Is it the pH? Is there anyone who can shed any light on this? Thanks.

    My experiences are that they like their coffee very strong. Hence, it is like tar at at times because of the process more than the water is my guess.

    I used to think that--and you may, in fact be right. But I've only very rarely found the coffee over-extracted or too strong (although, in fairness, I prefer it strong).

    I know many people from France that say, the reason why it's impossible to make bread taste the same here as in France is that the water here is so different. I have never been to France, but it is on my bucket list, if only to sit in a cafe and eat bread.

    I happen to go to Geneva a couple of times a year for meetings. Most times they are in the French Alps. My breakfast is always the fresh baguette type breads (I am sure made that morning as there are many bakeries all over the small towns, I learned what the word Boulangerie was very quickly) with a bit of proscuitto, and salami. No condo's needed. The bread is the star. Every morning the same. I rave about those breads.

    The tea and coffee in some parts of the world taste better than in other parts partly because of the mineral content of the water. I have found the same of drinking water in Santiago, Chile, which is in a mountainous region with a high mineral content in the water, so it wouldn't surprise me that it would also be true in Geneva, eastern France, and other mountainous regions of Europe.

    The minerals calcium and particularly magnesium make tap water taste better and make drinks made with tap water (coffee, tea, cold-brewed coffee, sun tea, Kool-Aid, etc.) taste better. This is the appeal of bottled "mineral water," whether carbonated or not.

    Lake Michigan water (with an equivalent calcium carbonate content of consistently about 137 mg/l) is on the low end of the range defined as moderately hard (120-180 mg/l). Some products sold as "mineral water" are no harder; some are. This US Geological Survey website shows a chart and map of water hardness in the US. As the map shows, terrain is not necessarily an indicator of water hardness; in the US, water hardness is high predominantly in the Rocky Mountains in the west and in some pockets around the Great Lakes but not in the Sierra Nevadas in the west, the Smoky Mountains in the east, or the Appalachians in the northeast.

    I like to use a particular type of faucet-mounted Pur filter that adds some calcium and magnesium to the water and improve its taste. You wouldn't want to run all your cooking water through such a filter; that would be a waste; you just want to use it for infused beverages such as tea, coffee, Kool-Aid, etc., and drinking water straight from the tap.

    So yes, harder water makes for better-tasting coffee, and if you want the water that you use to make your coffee even harder than what comes out of the tap, there are faucet-mounted and pitcher filters you can buy to increase the hardness (calcium and magnesium content) of your water.

    Water and how it effects the taste of food:

    When Lou Malnati's opened in Arizona, they had to adjust the ph of the AZ water to replicate the Chicago taste when making their dough.

    From the Lew Malnati's website:
    John on Nov 3, 2015
    "Will the dough be EXACTLY like Chicago? Arizona water leaves a bit to be desired when compared to Lake Michigan…"

    From Lou Malnati's on Nov 3, 2015:
    "Funny you should ask about the water! We totally agree with you, and we’re working with companies in Arizona to replicate the pH of Chicago water so the taste is just right."

    My Hot Dog U graduates in the Florida Keys and many other locations throughout the State of Florida cannot use tap water for simmering Vienna Beef hot dogs and Polish unless it's properly filtered. Most use bottled water. This is not just for health reasons, it's also because of the unfiltered water adversely effects the taste of the product.

    I've used the Big Berkey 2 stage water filter for years with great success for my cooking and drinking water. I also use a Berkey shower filter. I agree it's extremely important to have minerals in drinking water and I take Standard Process, Food Research, and Biotics vitamins and supplements to assure I have the proper minerals that are deleted through the water filtration system. https://www.berkeyfilters.com/berkey-wa ... r_Computer

    Interesting, Mark. Thanks for the info about the filters you use and other info.

    I'd like to revise my earlier statement about using mineral-filtered water: I think it's worth using not only for infused beverages but for anything for which water is a significant ingredient (although I don't know much about baking; I don't know how minerals in water affect the chemistry there). So far I haven't bothered to use it, though, for water that I'm only going to drain off after boiling pasta or eggs or vegetables, but your comments about hot dogs are making me reconsider.

    (Also, as an aside to new dog owners, you may think, like I did, that filtered water is the best for your puppy, and simply filtered water is fine that way, but high-end-of-medium-, large-, and giant-breed puppies should NOT drink mineral-filtered water because they should not ingest more calcium than what's formulated in large-breed puppy foods, or they may grow too fast and have joint problems later in life. This is why there are large-breed puppy foods; not because such breeds need more energy but because they shouldn't get too much calcium. I am not sure at what age, if any, this ceases to be an issue, but my impression is, not less than a year for medium/large breeds and not less than two years for large/giant breeds.)

    Katie, thank you for your post and links. I had concluded precisely the opposite--and so looked for some bottled water that was extremely low in both calcium and magnesium. Voss (a Norwegian water) is quite low on both counts. But I hadn't gotten around to testing the hypothesis yet. I had presumed that since the water in Evanston is apparently moderately hard (or harder), that I would need to go toward soft. Apparently, I need to go toward very hard. Fascinating. Now I'll get out there and see what is available commercially and run a few coffee-making tests. Again, many thanks for your information; it was precisely what I was looking for.

    Thank you. I'm glad to be of some help.

    "Some" help indeed!
    For anyone else who might be interested, I've spent a lot of hours on this and been dismayed to find that there is not one easily accessible list of bottled waters and their analyses. However, I have found a very good site that covers mineral waters from pretty much everywhere in the world and posts each one's mineral analysis. They list waters by country and the most well-known (most easily purchased?) waters have the analyses posted, though the website also lists every known water produced in that country. The site is finewaters.com I have learned from this site that both Apollinaris and Gerolsteiner (both from Germany) have some of the highest available calcium and magnesium levels of all mineral waters; although both are sparkling waters, both are also available as still. So I need to get out and buy me some very hard, good German mineral water, make some coffee, and report back.

    To touch on part of your original question, as well as the quote from Mark Malnati, hard water is slightly alkaline (pH > 7), soft water is slightly acidic (pH < 7); distilled water is neutral (pH = 7). (Neither of the latter two is known for tasting good.) So, any information you could find on the pH levels of various bottled waters could be useful in inferring their hardness and thus their mineral contents.
