Selection and purchase skills of Coffee Bean Grinder

For many beginners in coffee, choosing a bean grinder may be a headache. Whether to choose a manual coffee grinder or an electric coffee grinder. Today, I will introduce the selection and purchase skills of the coffee grinder to the coffee novice. Understand the coffee grinder purchase skills, for everyone to choose a practical coffee grinding opportunity is helpful.

The taste of coffee depends not only on the quality of coffee beans, but also on the quality of coffee grinders. An ideal bean grinder requires less heat production in the grinding process, uniform grinding particles and almost no electrostatic fine powder, because if you produce too much heat, it will cause the rapid loss of coffee aroma, uneven grinding will cause insufficient or excessive extraction, static electricity will have a greater impact on Espresso! Therefore, a good bean grinder is still very important for the taste of coffee!

Hand-held bean grinder: with its classical shape, conical grinding tools grind the beans, the function and appearance have almost not changed for hundreds of years, very good taste of life! The advantage is that there is no need to plug in, quiet, uniform particles, and there will be no overheating! The disadvantage is that if you grind a lot of coffee beans, you will be very tired! Hand grinding bean machine is more suitable for family use, because the general constant of drinking coffee will not be very large, shaking by hand will not be very tired, but the coffee made will taste better.

Small electric bean grinder: two blades rotate to cut up the beans, but the disadvantage is that they produce more heat, and the grinding bean particles are more uneven, which will produce static electricity. It is recommended not to use their own coffee brewing at home, because it has a greater impact on the taste of coffee. But for some small coffee shops, in the case of insufficient budget, you can consider, because the hand is too tired, other bean grinders exceed the budget, you can choose it!

Medium-sized bean grinder: like Flying Eagle, Pegasus and so on, this kind of bean grinder has the advantage of large amount of grinding beans, and its disadvantage is that it has a large amount of noise and generates static electricity, but general coffee shops can consider buying it because it grinds beans in a large amount and saves time and effort. Brewing single coffee is very suitable!

Top bean grinder: this kind of bean grinder is very suitable for large coffee shops, because it is suitable for Espresso, with semi-automatic coffee machine, but the noise is also a little louder, of course, it is absolutely the first choice for those who love coffee very much as the economic conditions permit!

[grinding essentials]

No matter what kind of bean grinder you use, you should master a few essentials:

1. The particle size should be uniform.

If it is uneven, the brewed coffee will taste incongruous. The finer the grinding particles, the more coffee ingredients are extracted, and the thicker the particles are, the less ingredients are extracted. In order not to destroy the original aroma of coffee, care should be taken when grinding to make sure that the particles are uniform.

2. Avoid friction to produce heat.

High-speed grinding of coffee beans will generate heat due to friction, which will deteriorate the coffee powder or lose the aroma components of the coffee. Manual grinders are particularly easy to produce heat, so attention should be paid to slow grinding.

3. Remove fine powder

When grinding coffee beans, it will produce some fine powder, such as mixing it, which will release bitter substances such as tannins when brewing. Fine powder is produced more in the use of electric bean grinder, some electric bean grinder with the function of automatic removal of fine powder, usually can be removed manually. Because the fine powder is lighter than the normal coffee particles, as long as the ground particles are shaken and blown, they can be removed.

In addition to mastering the essentials of grinding, which has an impact on the taste of coffee, the maintenance of the grinder is also very important; after the grinding is completed, the grinder should be cleaned immediately. The above fine powder can be attached to the grinder, and the taste of coffee will become worse after repeated use. Fine powder can be removed with a small brush.

In addition, rotary grinding teeth should also be cleaned. Coffee bean oil and fine powder adhere to the above, will affect its normal operation, can be cleaned with a fine bamboo stick or toothbrush.
