Know how much hot water to pour

You can complete the extraction ratio (*1) calculation to prepare the recipe right on the scale.
The scale accurately calculates the amount of hot water you should pour, reducing mistakes in making your coffee too strong or too weak.

You can see the extraction progress

The percentage display (*2) allows you to see how much hot water you should pour at a glance.
Furthermore, this scale no longer requires the amount of hot water (g) to be poured per pour to be calculated, which was previously necessary.
For example, if you are pouring hot water in 5 portions, pour in 20% increments, or in 4 portions, pour in 25% increments, until you reach 100% while watching the percentage display.
Even if the amount of coffee used changes, the percentage display remains unchanged, making it easier to manage recipes.

The percentage display becomes your North Star, guiding you to delicious coffee.

This is the ratio used to measure the amount of hot water to be poured relative to the amount of ground coffee.
Example: If you use 20g of ground coffee and the extraction ratio is 1:15, the total amount of hot water will be 300g. Displays "Current amount of hot water (g) ÷ Total amount of hot water (g) x 100 = Current ratio (%)".
