Getting the coffee-to-water ratio right is the foundation of a great cup. Too much coffee and it's bitter; too little and it's weak. Here's a simple guide to help you dial in the perfect ratio for your preferred brewing method.
The Golden Ratio: A Starting Point
The specialty coffee industry standard is 1:16 to 1:18 (coffee to water). This means:
- 1 gram of coffee to 16-18 grams (ml) of water
- Or roughly 1-2 tablespoons of coffee per 6 oz of water
This is your baseline. From here, you can adjust based on your taste preferences and brewing method.
Ratios by Brew Method
Pour-Over (V60, Chemex, Kalita)
Ratio: 1:16 to 1:17
For a 12 oz cup, use 20-22g of coffee with 340ml of water. Pour-over methods highlight clarity and brightness, so a slightly lighter ratio works well.
French Press
Ratio: 1:15 to 1:16
For a 12 oz cup, use 22-24g of coffee with 340ml of water. French press produces a fuller body, so a slightly stronger ratio balances the richness.
Drip Coffee Maker
Ratio: 1:17 to 1:18
For a standard 12-cup pot (60 oz), use 100-105g of coffee. Most drip machines work best with a slightly lighter ratio to avoid over-extraction.
Cold Brew
Ratio: 1:5 to 1:8 (concentrate)
Cold brew is brewed as a concentrate and diluted before drinking. Use 100g of coarsely ground coffee with 500-800ml of water, steep for 12-24 hours, then dilute 1:1 with water or milk.
How to Measure Accurately
Use a Scale
A digital kitchen scale is the most accurate way to measure coffee and water. Measuring by weight ensures consistency every time, regardless of grind size or bean density.
Volume Measurements (If You Don't Have a Scale)
- 1 tablespoon of whole beans ≈ 5-7g (depending on roast level)
- 1 tablespoon of ground coffee ≈ 5g
- 1 cup of water = 240ml
Adjusting to Your Taste
If your coffee tastes weak or sour: Use more coffee or less water (stronger ratio like 1:15)
If your coffee tastes bitter or harsh: Use less coffee or more water (lighter ratio like 1:18), or try a coarser grind
If your coffee tastes flat: Check your beans' freshness and grind size before adjusting the ratio

Final Tips
- Start with the recommended ratio and adjust in small increments (1-2g at a time)
- Keep notes on what works for different beans and roast levels
- Fresh beans make the biggest difference—use within 2-4 weeks of roasting
- Water quality matters—use filtered water for the best taste
Once you find your perfect ratio, brewing great coffee becomes second nature. Happy brewing!
