How to use the Coffee Calculator?
We've created a simple tool to help you calculate the ideal coffee to water ratio for different brewing methods - taking into account the volume of the drink, the desired strength, and the level of roast.
Step 1: Select the brewing method
First, choose the method of coffee preparation: V60, Filter, French Press, Aeropress, Keurig, or Espresso. Each has its own recommended coffee to water ratio and brewing time.
Step 2: Specify the desired volume of the drink
Select the number of cups: from 1 to 4. The calculator will automatically convert this to milliliters and adapt the calculation formula.
For espresso and aeropress, volumes of more than 2 cups are not available, as this contradicts the technical features of brewing.
Step 3: Choose the strength of the drink
For most methods, you can choose from light, standard, or strong coffee. The calculator changes the ratio of coffee to water according to the selected flavor intensity.
For espresso, the strength does not change - it is constant, and the corresponding setting is automatically turned off.
Step 4: Specify the roasting level
Choose between "Filter roast" or "Espresso roast". This affects the flavor profile and recipe calculation.
If you have selected the V60 or Filter method, the calculator will automatically select the appropriate roast "Under the filter", as these methods reveal the coffee in this profile.
Step 5: Click "Calculate recipe"
The calculator will show you the full recipe:
- brewing method
- water volume
- recommended temperature
- coffee to water ratio
- amount of coffee in grams (rounded to the nearest 0.5 g)
- approximate brewing time
Tip: experiment with the parameters to find the perfect recipe for your taste and type of grain.
Coffee is more than a drink. It is a tradition.
Coffee to water ratio: how to choose the right one?
The ideal ratio of coffee to water depends on the brewing method and the desired strength of the drink. Our calculator automatically takes this into account - but here are some basic guidelines if you want to get a better understanding of the principle.
We recommend three options depending on the desired strength:
- Light coffee - 1:18 (meets the SCA Golden Cup standard)
- Average strength - 1:16
- Strong coffee - 1:13
These methods are best suited for "under the filter" roasting, where the flavor is revealed as purely and flavorfully as possible.
Thanks to its longer brewing time and full immersion, the French press produces a rich cup:
- Easy - 1:18
- Average - 1:15
- Strong - 1:13
The flavor will be more "fleshy" and rounded - especially with medium roasting.
Like the V60, the Chemex requires a filter and fine grinding:
- Easy - 1:18
- Average - 1:16
- Strong - 1:13
Perfect for light to medium roasting.
A multifunctional method with a short brewing time. We use the ratio:
- The average ratio is 1:12
(You can vary it to your liking)
Please note: The Aeropress is usually used for 1-2 cups.
A unique method where the ratio is much lower:
- A typical ratio is 1:2
This means that 18 g of coffee makes about 36 g of drink.
For espresso, the option to change the strength is not used - it is always fixed.
All ratios are given as 1 gram of coffee to X grams (ml) of water.
Use our calculator to get accurate coffee and water values based on your parameters.
Tip: The exact ratio is just a starting point. Don't be afraid to experiment! The type of coffee, grind, water, and equipment all make a difference. And our calculator will help make this process easier.
