Coffee-to-Water Ratio Definition
The coffee-to-water ratio is calculated by dividing the weight of water (grams or ml) by the weight of coffee grounds (grams):
Recommended Ratios
| Ratio | Description |
|---|---|
| 1:17 | Standard ratio for balanced extraction |
| 1:18 | SCAA Golden Ratio (55g coffee per 1000g water) |
Adjust the ratio based on your brew method, coffee type, and taste preference. A lower ratio (e.g., 1:15) yields a stronger brew, while a higher ratio (e.g., 1:18) yields a lighter brew.

Frequently Asked Questions (FAQs)
What is the coffee-to-water ratio?
The coffee-to-water ratio is the proportion of coffee grounds to water used in brewing, expressed as a ratio (e.g., 1:17 means 1 gram of coffee per 17 grams of water).
What is the SCAA Golden Ratio?
The SCAA Golden Ratio is approximately 1:18, recommending 55 grams of coffee per 1000 grams (or ml) of water for optimal flavor extraction.
How does the ratio affect coffee taste?
A lower ratio (e.g., 1:15) produces a stronger, bolder coffee, while a higher ratio (e.g., 1:18) results in a lighter, milder flavor. Adjust based on preference.
What is caffeine?
Caffeine is a purine alkaloid (C8H10N4O2) found in coffee that stimulates the central nervous system, enhancing alertness and reducing fatigue.
How do I choose the right ratio?
The ideal ratio depends on your brew method, coffee type, and taste preference. Experiment with 1:17 or 1:18 ratios and adjust to suit your taste.
