BrewRatio.

Calculate the ratio and keep the recipe behind the cup

BrewRatio connects the coffee-and-water calculation to the brewing session you want to repeat. Enter the values you know, follow the relevant stages and keep the recipe and taste notes together. A useful comparison changes one recorded input at a time instead of relying on memory.

1. Calculate coffee, water or ratio from the two values you know.
2. Follow the chosen method’s timing and note the actual session.
3. Save the recipe and taste observations for the next comparison.
