Coffee bean powder: rich aroma, taste the essence of coffee

Coffee is an irresistible delicious drink, and the most important part of it is grinding coffee beans. Only properly ground coffee beans can release the most intense and mellow flavor, and truly experience the essence of tasting coffee.

1. The degree of grinding has a huge impact on the taste

Choosing the right grind is crucial when making a perfect cup of coffee. Different types and flavors of coffee require different degrees of fineness or coarseness to extract their best taste. A finer grind allows water to contact more surface area, thereby fully extracting the rich, diverse, complex and layered taste of the beans; on the contrary, a coarser grind reduces the contact area with water and slows down the time for water to penetrate into the interior, taking away some of the more bitter substances in the process, resulting in a softer taste.

2. Grinding time affects coffee extraction

In addition to the degree of grinding, grinding time is also an important factor affecting the quality of coffee bean powder. If the coffee beans are over-grinded, the powder will be too fine and lose the surface area required for contact with water molecules. On the contrary, if it is not fine enough, the aromatic substances and flavor components contained in the coffee beans cannot be fully released.

The optimal extraction time will also vary for different types of coffee machines. For example, in hand-pour or drip brewing, it is common and recommended to use about 20-30 seconds to complete the entire soaking and filtering process; while in espresso brewing, it may take less time to achieve the ideal effect.

3. Keeping it fresh is key

No matter what type and method you choose to grind your coffee beans, it is crucial to keep them fresh. Because once the coffee beans are ground into powder, their surface area increases, making them more susceptible to oxidation and moisture. This will cause the aroma and flavor compounds in the coffee beans to be lost quickly.

To keep the coffee bean powder fresh, it is best to store it in a sealed container in a cool, dry place away from direct sunlight. In addition, you should try to avoid buying too much coffee bean powder at one time and divide it into appropriate amounts before use to keep it fresh.

4. Taste comparison before and after grinding

If you are still unsure about the right grinding degree and time, please do not ignore a simple but effective method: taste comparison. You can choose coffee beans of the same batch, type, origin or similar flavor characteristics to make two cups of coffee under the same conditions with only different grinding degrees (such as fine and rough) for comparison.

This way, you can get a clear feel for the effect of different grind sizes on the taste of your coffee: a fine grind might give you a richer, fuller flavor, while a coarser grind might give you a softer, more balanced taste.

Conclusion

Grinding coffee beans is a crucial part of tasting coffee. By choosing the right grinding degree and time, and keeping it fresh, we can maximize the rich, diverse, complex and layered taste of coffee beans. Only in this way can we truly taste the essence of coffee.
