The scale helps you directly calculate the ideal extraction ratio so you can follow your coffee recipe precisely. The scale measures exactly how much hot water you need to add so your coffee doesn’t end up too strong or too weak.

The percentage display shows you how much water you need to pour without having to count each portion. For example, add 20% for five servings or 25% for four until you reach 100%. The scale adapts to different coffee quantities and simplifies recipe management.

The percentage display is your North Star, guiding you towards delicious coffee.
