So - a subjective subject has an objective standard. I've heard the same sheit about who makes the best Pizza.

But, let's look at this objectively - i.e., not about taste but about the wet-chemistry methodology used to produce coffee.

You have the beans: Surface area will control the rate of various extractions, hence the grind is important to control the following:

Soluble products:
With few exceptions, hotter water extracts more quickly and in larger quantities than colder water. This is potentially both positive and negative, depending upon what you wish to extract from the medium. Conventional coffee wisdom is that boiling water is preferred - and except in pressurized espresso makers, that waters' at 100 C. Most minerals must be in an ionic form if one wishes to extract them with water. There's an effect (common ion effect) that could potentially inhibit the extraction of certain minerals if the extraction medium is already high in said mineral. Organically bound minerals, on the other hand, typically are non-ionic and not particularly soluble (e.g., iron in your blood, copper in lobster blood). There's also the possibility of chelation, further complicating the issue (and the effect of temperature), as it may increase the solubility of poorly soluble minerals (eg, most forms of Calcium). The (nauseating)

Organic Product:
These are basically extracted into the system because they're mobilized by the hot-water (not dissolved in it to any significant degree!). If you look up what is called a soxhlet extraction, you'll see the relationship (Wikipedia [^]has a neat animated image). Again, super-heated water will affect this rate. In the typical drip coffee maker, this is a one-pass event so the variation (based upon water temp and grind) will be much more pronounced.

Bare in mind that none of the above even mentioned the degree of roasting (which would be a coffee specific modification to the processes). The roasting, however, causes a breakdown of many of the components (for the paranoid amongst us, like almost all thermal decomposition, it's free-radical chemistry). The partially oxidized oils may take on some partially ionic character, making them easier to extract (except they may bind more firmly to the substrate) - but they may also polymerize and become less soluble and more difficult to 'soften' with hot water for the extraction.

Keurig systems rely partially on elevated pressure to speed the atrocity they call brewing. They even try to apply this to tea!

If the forgoing was annoying enough, imagine that different filter porosity will effect contact time and amount of oils removed. Some (dumb) filter brands brag how much of the oil they'll absorb! Then, too, my favorite coffee maker type is vacuum drip - I have serious control over how long I brew without every boiling the coffee directly.

Putting all this emphasis on magnesium (vs. essentially distilled water, recommended by many coffee production methods/people/pundits/etc.) is ludicrous. Put a tiny pinch of epson salts into your coffee maker and see if it's better beyond the placebo effect.
