How to use the coffee brewing calculator
Select your brewing method, enter the final amount of coffee you want, and choose your preferred strength. The calculator will estimate the amount of ground coffee and water you need, along with a recommended grind size, water temperature and extraction time.
The result is a practical starting point. Coffee beans, roast level, grinder quality and personal taste can change the ideal recipe. If your coffee tastes too sour or weak, try a slightly finer grind or use a little more coffee. If it tastes too bitter or dry, use a coarser grind or shorten the brew time.

Frequently asked questions
What is the best coffee-to-water ratio?
For most filter coffee methods, a ratio close to 1 gram of coffee for every 15 to 17 grams of water is a reliable starting point. Stronger coffee uses less water per gram of coffee, while milder coffee uses more water.
How many grams of coffee should I use for 500 ml of water?
Using a balanced 1:16 ratio, 500 ml of water requires about 31 grams of coffee. You can adjust the dose slightly based on your preferred strength and brewing method.
Does grind size change the taste?
Yes. A finer grind usually increases extraction and can make coffee taste stronger or more bitter. A coarser grind reduces extraction and can make coffee taste lighter or more acidic.
