Calculator FAQ

Find answers to common questions

What is the perfect coffee to water ratio?

The perfect coffee to water ratio depends on your brewing method and taste preference. Generally, a 1:16 ratio (1g coffee to 16ml water) works well for most methods. For drip coffee: 1:15-1:17, AeroPress: 1:14-1:16, Chemex: 1:15-1:17. Start with these and adjust based on your taste preference.

How do I calculate coffee ratios?

To calculate coffee ratios, divide the amount of water by the amount of coffee. For example, 240ml water ÷ 15g coffee = 1:16 ratio. Use our Bean Ratio calculator to automatically compute the perfect amounts for your preferred strength and brewing method.

What's the difference between brewing methods?

Different brewing methods extract flavors differently. Drip coffee offers balanced flavor, AeroPress creates concentrated coffee with low acidity, and Chemex produces clean, bright cups with excellent clarity through thick paper filters. Each method requires different grind sizes and brew times.

Can I use this calculator for cold brew?

This calculator is optimized for hot brewing methods (drip, AeroPress, Chemex). Cold brew typically uses a stronger 1:8 to 1:12 ratio and requires different extraction times (12-24 hours). Check our Cold Brew recipe for specific guidance.

How does grind size affect my coffee?

Grind size is crucial for extraction. Fine grinds have more surface area and extract faster (good for espresso). Coarse grinds extract slower (good for French press). If your coffee tastes weak, try a finer grind. If it tastes bitter, try a coarser grind.

Should I use a scale to measure coffee?

Yes! Weight measurements are much more accurate than volume. A small digital scale ($20-50) ensures consistent, reproducible results. Most specialty coffee enthusiasts use scales for every brew.
