Coffee Ratio
A precise tool.
What is the Coffee Ratio & How does it work?
The coffee‑to‑water ratio is the cornerstone of brewing consistency. By standardising how much water is used per gram of coffee, baristas can reproduce the same flavour profile cup after cup, regardless of bean origin or roast level. A common starting point for many brewing methods is a 1:15 ratio, meaning 15 g of water for every gram of coffee. Adjusting the ratio higher (e.g., 1:17) yields a lighter, more delicate cup, while a lower ratio (e.g., 1:12) produces a richer, more concentrated brew. Understanding the mathematics behind the ratio empowers you to experiment confidently. Whether you’re scaling a recipe up for a larger batch or fine‑tuning a single‑serve pour‑over, the same formula applies.
W = C times R
W = water amount (g), C = coffee weight (g), R = brew ratio (water per coffee)

Frequently Asked Questions
What is a good starting point for coffee-to-water ratio?
A common starting point is a 1:15 ratio, meaning 15 grams of water for every gram of coffee.
How does changing the coffee-to-water ratio affect the taste?
A higher ratio (e.g., 1:17) yields a lighter, more delicate cup, while a lower ratio (e.g., 1:12) produces a richer, more concentrated brew.
Can I use this calculator for different types of coffee?
Yes, the calculator can be used for various types of coffee beans and roast levels to maintain consistency in flavor.
What is the purpose of a consistent coffee-to-water ratio?
A consistent ratio helps baristas reproduce the same flavor profile cup after cup, regardless of bean origin or roast level.
How do I adjust the ratio for a stronger coffee?
To make your coffee stronger, decrease the water-to-coffee ratio to around 1:12 or lower.
Is it better to use more water or less water for brewing?
The ideal amount of water depends on the desired strength. A higher water-to-coffee ratio makes a lighter, weaker coffee, while a lower ratio produces a stronger, richer cup.
Can I use this calculator with different brewing methods?
Yes, you can adjust the ratio based on your preferred brewing method to achieve optimal results.
