Why the Coffee to Water Ratio Matters
The secret to a great cup of coffee isn't just the beans; it's the chemistry between the coffee grounds and the water. This relationship is defined by the coffee-to-water ratio. Using a ratio allows you to scale your brewing regardless of whether you are making a single cup or a full carafe.
Understanding Common Ratios
- 1:15 Ratio: Results in a stronger, more concentrated cup. This is excellent for immersion methods like the French Press or for those who add milk to their coffee.
- 1:17 Ratio: A lighter, more delicate brew that highlights the floral and acidic notes in specialty light-roast beans. Often preferred for V60 or Chemex pour-overs.
- The "Golden Ratio" (1:16.67): The Specialty Coffee Association (SCA) suggests 55 grams of coffee per 1000ml of water, which rounds to approximately 1:16 or 1:17.
Realistic Brewing Examples
To put this into perspective, here are common scenarios handled by our calculator:
| Method | Coffee Weight | Water Weight | Ratio |
|---|---|---|---|
| Standard Pour Over | 20g | 320g (320ml) | 1:16 |
| Large French Press | 50g | 750g (750ml) | 1:15 |
| Double Espresso | 18g | 36g (36ml) | 1:2 |
Tips for the Perfect Brew
- Use a Scale: Measuring by volume (spoons/cups) is inaccurate because coffee density varies by roast. Always measure in grams.
- Water Quality: Since coffee is 98% water, use filtered water for the best flavor profile.
- Adjust for Taste: If your coffee is too bitter, try a coarser grind or a slightly higher ratio (e.g., move from 1:15 to 1:16). If it's sour or weak, use a tighter ratio or a finer grind.
