Grinding coffee beans: coarse and fine

Grinding coffee beans: coarse and fine

Hand brewing is a delicate method of making coffee, and one of the most important steps is grinding the coffee beans. Different degrees of grinding will directly affect the taste and mouthfeel of the coffee. In the hand brewing process, we can choose the appropriate bean size according to personal preference and the equipment used.

Why do we need to control the size of beans?

Controlling the size of the beans can adjust the extraction time and the contact area between water and coffee particles, thus affecting the taste of the final extracted coffee. If the beans are broken into too small particles, the water will pass through very quickly, resulting in too short an extraction time and a turbid taste; on the contrary, if the beans are cut into too large pieces, the water flow rate will be slow and it will be difficult to fully extract the aroma and flavor.

How to choose the right bean size?

First, you need to consider the type of equipment you are using. For a paper drip pot, a finer grind is ideal. For a metal filter hand-pour pot or French press, a medium to coarse grind is more suitable. Secondly, personal taste is also an important factor. If you like a strong coffee taste, you can try a finer bean powder; if you prefer a light and soft taste, you should choose a coarser bean.

How to grind manually?

Manual coffee bean grinder is a common tool and very convenient for home use. First, you need to put the coffee beans into the container and adjust the blade spacing or knob position according to the desired coarseness. Then start turning the handle at an even and steady speed.

Precautions

When grinding coffee beans manually, please pay attention to the following points:

1. Keep it steady: Excessive force or uneven turning may result in different particle sizes.
2. Avoid over-processing: Avoid processing the beans too finely, otherwise it will affect the final taste of the extraction.
3. Cleaning and maintenance: Clean and maintain the coffee bean grinder regularly to ensure its normal operation and long-term use.

Conclusion

Hand-brewed coffee is a delicate enjoyment, and choosing the right bean size is the key to making delicious coffee. By understanding the effects of different grinding degrees on the extraction process and taste, we can adjust the flavor of hand-brewed coffee according to personal preferences.
