Longshot brew bench / Coffee ratio calculator
Good coffee.
Down to the gram.
Choose your method. Find your ratio. Make it yours.
A useful place to start for a paper-filter pour-over. Keep your grind and pouring steady while you compare ratios.
A good starting point.
Then, make it yours.
Ratio is one part of your recipe. Your beans, grind, water and brewing method all have a say in the cup.
| Coffee | Water |
|---|---|
| 15 g | 240 g |
| 20 g | 320 g |
| 30 g | 480 g |
| 40 g | 640 g |
What does a 1:16 ratio mean?
One gram of ground coffee for every 16 grams of brewing water. Multiply coffee weight by the second number: 20 × 16 = 320 g of water. If you already know your water amount, divide it by the ratio to find your coffee weight.
How do I make my cup stronger?
With the same coffee weight, a lower water ratio uses less water for a more concentrated brew. Try a small adjustment and keep the other variables steady. If the cup tastes sour or bitter, grind and extraction may need attention too; ratio alone does not fix every cup.
Why is espresso calculated differently?
Espresso recipes compare dry ground coffee with the weight of the drink in the cup. At 1:2, 18 g of coffee gives a target of 36 g of espresso. That is beverage yield, not the amount of water to put in your machine. Follow your equipment’s instructions and adjust to taste.
Is cold brew ready to drink at this ratio?
The cold brew setting is for concentrate. After steeping and straining, dilute to your taste with water or milk. The calculation does not include that extra liquid. The grounds also retain water, so the concentrate you collect will weigh less than the water you started with.
Do I need a coffee scale?
A kitchen scale that reads grams is a useful start. Scoops vary, and different beans take up different amounts of space. Weighing makes a recipe easier to repeat. For espresso, a scale with finer resolution can help.
The math is sorted.
Now for the good beans.
