This guide explains how to grind coffee beans without a grinder, which tools work best, and how each method affects brewing. These techniques help you get close to your desired grind size even without special equipment.
Why Grind Size Matters
Before learning the different methods, it helps to understand grind size. Grinding affects how water extracts flavor from the beans.
- Coarse grind works best for French press
- Medium grind is ideal for drip coffee
- Fine grind is used for espresso-like brews
Knowing how to control grind size helps you choose the right method.

- Place the knife flat over them.
- Press firmly to crack the beans.
- Continue pressing to crush them smaller.
Best grind size
Medium to coarse.
How to Choose the Best Method
- For espresso-style brews: Use mortar and pestle.
- For drip coffee: Use a rolling pin, blender, or food processor.
- For French press: Use hammer, tenderizer, or rolling pin.
Choose the method based on the grind size your brewing method needs.
Tips for Grinding Coffee Beans Without Grinder
- Work in small batches for better control.
- Shake or stir between crushing to even out the grind.
