Best Water for Coffee [Right Coffee to Water Ratio]

There are quite a number of variables to consider for a perfect cup of coffee. Well, the brand of coffee you choose to brew with is one factor; but the most important is the quality of water because a cup of coffee consists mainly of water.

Being good at water chemistry does not translate to a good cup of coffee; for conventional coffee, the Specialty Coffee Association recommends high clarity odor-free water with absolutely no chlorine residual.

It is somewhat true that your coffee will taste better if your drinking water tastes good. Hard water will more likely make a better cup of coffee compared to softened water or water softened at home; since there is some quantity of calcium and magnesium dissolved in hard water.

The two minerals especially magnesium will bring out the best flavoring in coffee; on the contrary, soft water or water with sodium instead of the two minerals will give out a flat, plain taste. The only major drawback of using hard water is its capability to gradually affect the working of an espresso machine because of scaling. However, there will be very little impact on the manual brewer.

Apart from the mineral content of water, the pH level and water temperature are other necessary factors to look into; the optimum pH is 7.0 although the allowable range is 6.5 to 7.5. Distilled water is the best water for coffee since it provides the required pH levels.

To get the all-important water chemistry right, discussed below are some four water distillers that use the best distilling technology convenient for use in your home.

For the correct coffee to water ratio, you may initially try out varying amounts to get the right ratio of coffee and water. Nevertheless, it is recommended to put approximately six ounces of water for every 1 to 2 tablespoons of ground coffee.

Your preferred amount may change so be free to experiment with varying amounts. In case you get the perfect ratio, continue with the same. While at it, perform a number of tests on the ‘cup lines’ on the brewer to know how they stack up. Several brewers have their cups differently gauged and you may notice that it will not be exactly six ounces.


 As for the water temperature, use near boiling water with temperatures just slightly in excess of 90 degrees Celsius (between 190 to 208 degrees Fahrenheit) at the standard atmospheric pressure since hotter water is more desired for drip coffee as compared to espresso.

You will find the “sweet spot” where the well mineralized hot water with drips over the right amount of coarsely ground coffee beans.
