Coffee bean grinding: from granules to powder

Importance of Grinding Coffee Beans

Grinding coffee beans is a key step in determining the taste and flavor of a cup of coffee. From granules to powder, each stage will have an impact on the final coffee quality. Therefore, mastering the correct grinding method and techniques is basic knowledge that every coffee lover must have.

Choosing the right grinding equipment

Before we start, we need to choose a suitable coffee bean grinder. There are two types of grinders available on the market: manual and electric. The manual type is suitable for those who like to personally participate in the production process, pursue higher quality or use it when traveling; while the electric type is more convenient and quick, suitable for daily use.

Adjust the appropriate thickness

According to different brewing methods and personal taste preferences, we need to adjust the coarseness and fineness to achieve the ideal effect. Generally speaking:

• Superfine: used for Italian espresso, Turkish and other brewing methods.
• Fine: Suitable for hand pouring, dripping, etc.
• Medium: Suitable for French press, siphon, etc.
• Coarse: For cold brew, French press, etc.

Preparation before grinding

Before we start grinding, we need to do some preparation:

1. Clean equipment: Make sure the coffee bean grinder is clean and free of impurities that may affect the taste of the coffee.
2. Measuring coffee beans: Choose the right amount of coffee beans to grind according to your needs and taste. It is recommended to only take enough for one brew each time to avoid long-term exposure to air, which may cause quality degradation.

Correct operation steps

(1) Adjust the thickness:

After putting the coffee beans into the machine, adjust the scale or button according to the desired coarseness. For manual machines, you need to control the grinding time based on personal experience and feeling.

(2) Start grinding:

Start the coffee bean grinder and let it run until completion. During the whole process, keep the machine steady to avoid uneven particle size.

(3) Check particle size:

After stopping the machine, open the lid and check the particle size. If you find too many fine particles or large pieces of beans are not completely crushed, you need to adjust the scale or re-operate.

Save and use

To maintain the freshness and taste of coffee beans, they should be used as soon as possible after grinding. If they cannot be brewed immediately, it is recommended to store them in a sealed container in a cool, dry place away from direct sunlight.

Conclusion

By choosing the right coffee beans, adjusting the right coarseness, and following the right steps, we can get a cup of coffee with a strong taste and rich flavor. I hope the guidance provided in this article will help you make better coffee at home.
