Frequently Asked Questions (FAQ)

1. What is a pour over calculator?
It’s a tool that helps determine the right coffee-to-water ratio based on brew strength and target volume.

2. Why is coffee-to-water ratio important?
It ensures balance—too much coffee tastes bitter, too much water tastes weak.

3. What ratios does this calculator use?
Strong (1:13), Regular (1:15), and Mild (1:17).

4. Can I use this tool for other brewing methods?
It’s optimized for pour over, but ratios can also guide drip or Chemex brewing.

5. What is bloom water?
It’s the first pour, about 2–3x the coffee weight, that helps release gases from fresh coffee.

6. How do I know which grind size to choose?
Medium is the standard, but you can experiment with medium-fine or medium-coarse for taste adjustments.

7. Does the calculator tell me brew time?
No, but pour over usually takes 3–4 minutes depending on grind and pour speed.

8. Can I brew stronger than the “strong” option?
Yes, but 1:13 is already quite concentrated—beyond that it may taste overly intense.

9. Is this calculator beginner-friendly?
Yes, it guides you step by step with clear recipes.

10. Can I scale recipes for multiple cups?
Yes, just enter the total amount of coffee you want (e.g., 700 ml for two mugs).

11. What happens if I enter less than 50 ml?
The tool will prompt you to enter a minimum of 50 ml.

12. Why does grind size matter?
It affects extraction—fine grind extracts faster, coarse grind slower.

13. Does this tool replace a coffee scale?
No, but it complements one by giving exact measurements to follow.

14. Can I save recipes for later use?
Yes, you can copy or share them instantly.

15. What if my coffee still tastes off?
Try adjusting grind size, water temperature (92–96°C), or pouring technique.

16. Is blooming always necessary?
Yes, especially with fresh beans, as it improves flavor clarity.

17. How accurate are the measurements?
The calculator uses standard brew ratios used by professional baristas.

18. Can I use this for iced pour over?
Yes, brew a stronger ratio (1:13) and pour over ice to balance dilution.

19. Do I need a gooseneck kettle?
It’s recommended for precise pouring, but not required.

20. How is this better than guessing ratios?
It eliminates inconsistency, ensuring every cup tastes just right.
