Does grinding coffee beans finer taste better?

introduction

Coffee is one of the most popular drinks in the world, and the effect of the grind degree of coffee beans on the taste of coffee has attracted much attention. Some people think that the finer the grind, the better the taste; however, this view is not entirely correct. This article will explore the relationship between the grind degree of coffee beans and the taste, and explain why grinding too fine may not always be a good thing.

1. Coffee bean grinding degree and extraction time

The first thing to understand is that the finer the ground coffee bean is, the longer it takes for water molecules to flow through it. This means that it takes longer to extract all the aroma and flavor from the ground coffee during the brewing process.

If you use a coarser grind for espresso (like in a French press), the water will have to pass through fewer layers. In contrast, using a very fine grind (like in an espresso machine) will require the water to pass through more layers to extract.

Therefore, the degree of grinding of coffee beans is closely related to the extraction time. Too fine a grind will result in a longer extraction time, which may have a negative impact on the taste.

2. Coffee bean grinding degree and acidity

Another factor to consider is the acidity in the coffee. Acidity refers to the bright and refreshing taste that certain compounds in coffee, such as citric and malic acids, provide.

When we brew with a coarser grind, the water comes into contact with more air as it passes through the okara. This contact can reduce some volatile compounds and lower the acidity in the coffee.

Conversely, if you brew with a very fine powder, the water flows faster and is less exposed to air. This allows more volatile compounds to be retained and increases the acidity in the coffee.

3. Coffee bean grinding degree and bitterness

In addition to increasing acidity, overly fine fats can also increase bitterness in coffee. When water passes through fine powders, it extracts more caffeine and other bitter compounds.

While some people like strong bitterness, excessive bitterness may mask the other complex and rich flavors in the coffee. Therefore, it is very important to grind moderately when pursuing a balanced taste.

4. Coffee bean grinding degree and sediment

A final factor to consider is the sediment produced during the brewing process. Finer grinds generally produce more sediment, which can affect the coffee drink itself.

If you don't like to find a lot of residue at the bottom of the cup, you should choose a coarser powder for brewing. This will reduce the sediment and make the taste more refreshing.

in conclusion

In general, it is not the case that the finer the grind, the better. Proper selection of the degree of grinding of coffee beans is essential to achieving the ideal taste.

If you prefer a sour and refreshing taste, you can try brewing with a finer powder. If you prefer a strong taste and less sediment in the coffee, you should choose a coarser powder.

The most important thing is to try and adjust according to your personal taste preferences. Only through constant experimentation can you find the degree of coffee bean grinding that best suits your taste needs.

Whether you are a coffee lover or a professional brewer, you should understand the impact of the degree of grinding of coffee beans on the final taste and pay attention to it during the brewing process.
