IF ADDING TO ONE LITER

Add about 4 to 8 drops of EMDROPS per liter of purified water, if you want a subtle and smooth taste to the water.

Add about 10 to 20 drops (1 mL) of EMDROPS per liter of purified water, if you want a more obvious mineral water taste.

IF ADDING TO 1 GALLON

About 1 mL of EMDROPS per gallon of purified water for subtle taste, and about 1/2 teaspoon per gallon for a more obvious mineral water taste.
Please see more detailed ranges below:

Add about 16 to 32 drops (approx 0.8 to 1.5 mL) of EMDROPS per gallon of purified water, if you want a subtle and smooth taste to the water.

Add about 2 to 4 mL of EMDROPS per gallon of purified water, if you want a more obvious mineral water taste.

In general, it is best to start off at the low end of the range, and then add more EMDROPS in increments until you find the taste that works for you.
