Enter the total grams of water (g) and the total grams of coffee (g) into the Coffee Ratio Calculator. The calculator will evaluate and display the Coffee Ratio. 

Coffee Ratio Formula

The following formula is used to calculate the Coffee Ratio. 

CFR = W / C
  • Where CFR is the Coffee Ratio (water:coffee)
  • W is the total grams of water (g) 
  • C is the total grams of coffee (g) 

To calculate the coffee ratio, divide the grams of water by the grams of coffee.

How to Calculate Coffee Ratio?

The following example problems outline how to calculate Coffee Ratio.

Example Problem #1:

  1. First, determine the total grams of water (g).
    • The total grams of water (g) is given as: 32.
  2. Next, determine the total grams of coffee (g).
    • The total grams of coffee (g) is provided as: 2.
  3. Finally, calculate the Coffee Ratio using the equation above: 

CFR = W / C

The values given above are inserted into the equation below and the solution is calculated:

CFR = 32 / 2 = 16:1 (water:coffee)

FAQ

What is the ideal coffee ratio for brewing?

The ideal coffee ratio can vary depending on personal taste and the brewing method used. However, a commonly recommended starting point is a 1:16 coffee to water ratio, meaning for every 1 gram of coffee, you use 16 grams of water. This ratio can be adjusted to taste.

How does the grind size of coffee affect the coffee ratio?

The grind size of coffee can significantly affect the extraction rate and thus the taste of the coffee. A finer grind increases the surface area in contact with water, leading to a stronger brew. This might require adjusting the coffee ratio to achieve the desired strength without bitterness.

Can I use the coffee ratio calculator for any brewing method?

Yes, the coffee ratio calculator can be used for various brewing methods, including drip coffee, French press, and espresso. However, keep in mind that different methods may require slight adjustments to the ratio for optimal results.
