Every coffee bag gives different instructions. Every recipe uses different measurements. Heres a simple guide that actually works.
The Standard Ratio: 1:15 to 1:17
For every 1 gram of coffee, use 15-17 grams of water. This is the range most coffee professionals recommend.
In practical terms:
- One cup (8 oz / 240ml): 14-16 grams of coffee (about 2 tablespoons)
- Two cups (16 oz / 475ml): 28-32 grams of coffee (about 4 tablespoons)
If You Dont Have A Scale
Use this rule of thumb: 2 tablespoons of ground coffee per 6 ounces of water.
Its not as precise as weighing, but it gets you in the ballpark for a standard-strength cup.
Adjusting For Taste
Coffee too weak? Add more grounds or use less water. Try a 1:14 ratio.
Coffee too strong? Use fewer grounds or more water. Try a 1:17 ratio.
Small adjustments make a big difference. Change one variable at a time until you find your preferance.
Different Methods Need Different Amounts
These are starting points—adjust to taste:
- Drip machine: 2 tbsp per 6 oz water
- French press: Slightly more, around 2.5 tbsp per 6 oz
- Pour over: 2 tbsp per 6 oz
- Cold brew: Much more—1:5 ratio for concentrate
- Espresso: 18-20g for a double shot
Why Measuring Matters
Eyeballing works until it doesnt. One day your coffee tastes perfect, the next its weak or bitter. Consistant measurements mean consistant results. A kitchen scale pays for itself in better coffee.
Start Here, Then Experiment
Begin with 2 tablespoons per 6 ounces. Brew a cup. Taste it. Too strong? Use less next time. Too weak? Use more. After a few tries, you’ll know exactly what works for you.
