Golden Ratio Coffee Calculator

Coffee lovers know that the secret to a truly satisfying cup lies in balance. Too much coffee and your brew turns bitter and overpowering. Too little, and you’re left with a weak, watery taste. That’s where the Golden Ratio Coffee Calculator comes in—a smart, easy-to-use tool designed to help you measure the exact amount of coffee or water you need for the perfect brew.

Whether you’re a beginner experimenting with home brewing or a seasoned barista seeking consistency, this calculator ensures every cup you make is smooth, balanced, and full of flavor.

What is the Golden Coffee-to-Water Ratio?

The golden ratio for coffee is 1:16, meaning 1 gram of coffee for every 16 grams (or milliliters) of water. This ratio is widely regarded as the standard for balanced flavor.

However, taste is subjective—some people prefer stronger brews (1:14) while others enjoy lighter ones (1:18). The calculator allows you to set your own ratio so you can fine-tune your brew to match your preferences.

3. Leave the default ratio at 1:16.
