How many levels should I choose for automatic coffee machine grinding? Analysis of coffee bean grinding degree of semi-automatic coffee machine

The appropriate level for grinding coffee beans in an automatic coffee machine varies depending on the machine model and personal taste, and usually requires trial and adjustment. The finer the grinding, the faster the extraction speed and the richer the taste; conversely, the coarser the grinding, the slower the extraction speed and the relatively light taste. It is recommended to select the appropriate level and make fine adjustments according to the coffee machine manual and personal preferences to achieve the best extraction effect. The coffee bean grinding level of a semi-automatic coffee machine also needs to consider the performance of the grinder and the type of coffee beans.

In busy modern life, coffee machines have become an indispensable helper for many families. For friends who love coffee, how to choose the right grinding gear to ensure the best taste of every cup of coffee is undoubtedly a topic worth discussing. This article will analyze in detail the different requirements of automatic coffee machines and semi-automatic coffee machines on coffee bean grinding degree to help you find the most suitable grinding gear.

1. Automatic coffee machine and coffee bean grinding degree

Automatic coffee machines usually have a one-button operation function. In order to match this feature, their built-in grinding devices often have fixed grinding gears set. These gears are usually divided into coarse grinding, medium grinding and fine grinding to adapt to different types of coffee beans and different brewing methods.

Coarse grind: Suitable for dark roasted coffee beans that require high pressure brewing. Coarsely ground coffee beans have larger particles, which helps slow down the water flow, allowing hot water to fully contact the coffee powder and extract a richer taste.

Medium grind: Suitable for most common coffee beans and brewing methods. The particles of medium grind coffee beans are moderate. It will not cause insufficient extraction due to too fast water flow, nor will it affect the extraction efficiency due to too large particles.

Fine grinding: Suitable for Italian coffee that requires precise control of extraction time. Finely ground coffee beans have finer particles, which can increase the contact area with hot water and help to fully extract coffee in a short time.

2. Semi-automatic coffee machine and coffee bean grinding degree

Compared with automatic coffee machines, semi-automatic coffee machines have more sophisticated requirements on the grinding degree of coffee beans. The reason is that semi-automatic coffee machines require manual control of various parameters in the brewing process, including water temperature, pressure, time, etc. The appropriate grinding degree is crucial to ensuring the taste of the coffee.

Semi-automatic coffee machines usually don’t have a built-in grinding device, which means you need to use a separate grinding tool or manually adjust the grind size of the coffee beans. For beginners, it is recommended to choose a medium-fine grind size as a starting point, and then fine-tune it according to personal taste.

In actual operation, there are many factors that affect the grinding degree of coffee beans, including but not limited to the type of coffee beans, freshness, roasting degree, and personal preference of the brewer. Choosing the appropriate grinding level requires comprehensive consideration of many factors.

3. How to choose the appropriate grinding gear

1. Understand the characteristics of coffee beans : Different types of coffee beans have their own unique characteristics, such as acidity, sweetness, bitterness, etc. Choosing the appropriate grinding gear according to the characteristics of the coffee beans will help highlight its unique flavor.

2. Practice adjustment : When trying for the first time, you can make adjustments based on the medium grinding degree and gradually find the grinding gear that suits you best.

3. Listen to the sound : During the brewing process, pay attention to the sound of water flowing into and out of the coffee powder. The right degree of grinding will make the sound pleasant and even.

4. Observe the extraction : Observe the extraction process of coffee. The appropriate grinding degree will make the coffee liquid present the ideal color and oil in a short time.

5. Taste adjustment : The most important thing is to fine-tune according to your own taste. If you like a strong taste, you can choose a finer grinding degree. If you like a softer taste, you can choose a coarser grinding degree.

Through the above analysis, I believe you have a deeper understanding of the requirements for coffee bean grinding degree for automatic coffee machines and semi-automatic coffee machines. Choosing the right grinding gear can allow you to enjoy the coffee taste comparable to that of professional coffee shops at home. With continuous experimentation and adjustment, you will find the best grinding gear for yourself.
