How to grind coffee beans without a machine?

Grinding coffee beans is one of the important steps in making delicious coffee. Although there are various electric and manual coffee bean grinders to choose from in modern life, if we don't have these devices, we can still use some simple methods to grind coffee beans manually.

First, we need to prepare a sturdy and sharp knife. Place a clean knife on a stable countertop and pour the coffee beans onto the tip of the knife. Next, hold the handle of the knife with your other hand and press and rotate the blade hard to grind the coffee beans into powder.

Another method is to use a hard and flat surface to help us grind the coffee beans. For example, find a marble slab or other smooth and flat surface outdoors or on a balcony. Take a suitable amount of coffee beans and spread them on the board. Then use another heavy tool with a flat bottom (such as a hammer) to hit and roll on the surface to crush until the desired fineness is reached.

In addition to the above two methods, you can also try using a small and sturdy plastic bag to grind the coffee beans. Put an appropriate amount of coffee beans into the plastic bag and seal it. Then, use a hammer or other hard object to gently tap and roll on the plastic bag until the coffee beans become the desired fine powder.

No matter which method you choose, there are a few things to keep in mind. First, make sure you use clean tools and surfaces to avoid contaminating the coffee grounds with impurities. Second, keep a steady and firm pressure during the grinding process to get a uniform and fine powder.

Hand-grinding coffee beans may take some time and patience, but it helps you create a delicious cup of coffee with a rich flavor and aroma. Try these simple methods and enjoy your own freshly brewed coffee!
