Practical Example

Imagine you want to make 3 cups of French Press coffee using 2 tablespoons of coffee per cup at a Standard strength (1:16).

• Enter 2 in the coffee amount field, select tablespoons as the unit, and set serving size to 3.
• Choose Standard (1:16) as brew strength.
• Select French Press as brew method.

After clicking Calculate, the tool will:

• Convert tablespoons to grams (1 tbsp ≈ 5.3g).
• Multiply by 3 cups = 31.8g coffee.
• Calculate water needed: 31.8g × 16 = ~509 ml water.
• Provide a brewing tip: “Let coffee steep for 4 minutes before pressing gently.”

This ensures your French Press brew comes out perfectly balanced without guesswork.
