Abstract: A method for brewing a beverage, a water concentrate for brewing the beverage and the beverage thereof are provided, wherein the water concentrate includes a hardness between 10,000 ppm and 100,000 ppm, a calcium ion concentration between 300 ppm and 10,000 ppm, a magnesium ion concentration between 200 ppm and 20,000 ppm, a sodium ion concentration between 30 ppm and 1,000 ppm, a potassium ion concentration between 30 ppm and 1,000 ppm, a bicarbonate ion between 10 ppm and 300 ppm, and a pH between 6 and 9. By controlling the hardness and mineral composition of the water concentrate, the invention increases the affinity to amino acids, flavonoid compounds, polyphenolic compounds, terpenoid compounds, alkaloids, and organic acids in coffee or tea beverages, and adds the content of substances which are helpful to the human body in addition to improving the taste and flavor of the beverages.

Abstract: A mineral water producing method includes the steps of inputting basic data to obtain data about human mineral intake and data about average mineral intake from food; selecting a water supply area to obtain data about mineral intake from daily water intake; selecting an eating habit and a physical/mental condition; inputting personal body weight and calculating mineral intake; setting a daily water intake and calculating a daily mineral supplement; and outputting mineral water. A mineral water producing apparatus includes a water inlet and a water outlet; a first filter being connected at a first end to the water inlet and at a second end to the water outlet; at least one mineral substance container being located between and connected to the second end of the filter and the water outlet; and a controller for controlling the mineral substance container to supply a mineral substance.
