Coffee grind degree 1 to 10, which is the center of fineness?

The center of fineness of coffee grind

The grinding degree of coffee is one of the important factors that determine the taste and flavor of coffee. In the coffee industry, 1 to 10 is often used to represent different degrees of grinding. So, what value does the fineness center refer to? This article will explore this issue.

1. The effect of coffee coarseness on taste

First, we need to understand the effect of different coarseness on the taste of coffee. A coarser grind causes the water to pass through faster, extracting fewer and larger particles, resulting in a deep, rich, full-bodied coffee with a bitter taste. Conversely, a finer grind causes the water to pass through slower and extracts more and smaller particles, resulting in a refreshing, bright, light coffee with an acidic and floral atmosphere.

2. Common types of teapots on the market and their characteristics

The common coffee grinding degree range on the market is 1 to 10, where 1 represents the coarsest grinding and 10 represents the finest grinding. Within this range, different values ​​represent different coffee making methods and taste characteristics.

2.1 Coarseness 1-3: Coffee in this range is suitable for cold brew, French press, etc. Because the particles are larger, water passes through faster and less substances are extracted, so the taste is richer, fuller and bitter.

2.2 Coarseness 4-6: Coffee in this range is suitable for drip and siphon brewing. The particle size is moderate, the water passes through at a moderate speed, and more and evenly distributed substances can be extracted. Therefore, the taste is refreshing, bright, light, and has a certain acidity and floral atmosphere.

2.3 Coarseness 7-10: Coffee in this range is suitable for high-pressure production methods such as espresso machines. The particles are small and uniform, and water passes through slowly and can extract more substances. Therefore, the taste is rich, full, and has a strong bitter taste.

3. What is the value of the fineness center?

According to the common types of teapots on the market and their characteristics, we can conclude that the fineness of coffee grinding should be between 4 and 6. Coffee powder within this range is suitable for most production methods and can extract various flavor substances in coffee beans in a balanced manner, making the taste more balanced and diversified.

4. Grinding degree selection and personal preference

Although the fineness ranges from 4 to 6, the final choice depends on personal taste preference. If you like a refreshing and bright coffee with an acidic and floral atmosphere, you can try a finer grind; if you prefer a rich and full-bodied coffee with a bitter taste, you can choose a coarser grind.

5. Conclusion

In summary, the fineness of coffee grinding should be between 4 and 6. Coffee powder within this range is suitable for most production methods and can extract various flavor substances in coffee beans in a balanced manner, making the taste more balanced and diverse. Of course, the final choice still depends on personal taste preference.
