Coffee bean grinding: brew or brew?

Coffee is a popular beverage that can be made in many different ways. One of the key steps is grinding the coffee beans. But should coffee beans be ground before brewing or before brewing? This question has always been controversial. This article will explore this issue and provide some relevant information and suggestions.

1. Characteristics of coffee beans

To understand when to grind coffee beans, you first need to understand the characteristics of the coffee beans themselves. Factors such as freshness, degree of oxidation, and powder size will affect the taste of the final coffee.

Freshness is essential to maintaining the flavor of coffee. The fresher it is, the more volatile substances it contains, and the better the taste. As time goes by, the volatile substances gradually decrease, resulting in a worse taste.

The degree of oxidation will also affect the taste of the final coffee. The longer the coffee beans are exposed to the air, the higher the degree of oxidation. Over-oxidized coffee beans will lose their original flavor and aroma.

Grind size is another important factor. Different brewing methods require different sizes of coffee grounds to extract the best taste. Grinding too fine or too coarse will result in a bad taste.

2. Grind before brewing

Some people advocate grinding the coffee beans before brewing, believing that this maximizes freshness and flavor.

Storing the beans whole prevents them from being exposed to air, which reduces oxidation, and grinding only when you really need it ensures that every cup is freshly brewed.

In addition, crushing before brewing also allows you to adjust the powder size according to your specific needs. For example, if you want to make a strong and strong espresso, you can choose a finer powder; if you like a light filter coffee, you can choose a coarser powder.

3. Grind before cooking

Others advocate grinding the coffee beans before brewing, arguing that this allows for better control over brewing time and temperature, resulting in a better taste.

Storing the whole coffee bean preserves its freshness and flavor. However, crushing it on the spot before brewing may result in an uneven distribution of powder size. This may result in some particles being too fine or too coarse, affecting the final taste.

By breaking your coffee beans into the appropriate size ahead of time and storing them in containers, you can better control the time and temperature required for each brew. This helps ensure that every cup has a similar and ideal taste.

4. Conclusion

Grinding your coffee beans before brewing or before brewing has its pros and cons. The best time to do this will depend on personal preference, the equipment you use, and your chosen brewing method.

If you're looking for maximum freshness and flavor, as well as a higher preference for powder size, grinding your coffee beans before brewing may be for you.

If you care about controlling brewing time and temperature and want each cup to have a similar and ideal taste, then grinding the coffee beans before brewing may be more suitable for you.

Whichever method you choose, remember to choose high-quality, fresh coffee beans that suit your taste preferences. Only in this way can you make a perfect and satisfying cup of coffee.
