The beauty of coffee is that you can participate in the last mile before you drink it. Even if it is tasted in the end, coffee is more fun to grind than tea and more fun to grind and brew than wine.

But many people are used to buying ready-made powder or asking the store to grind it into a large bag at a time and use it slowly at home. In fact, the best way is to grind and cook, or grind a small amount and use it quickly.

Since coffee can bring so much fun, we have to know how important the bean grinder is. If you want to drink freshly brewed coffee in your own home, how to choose a bean grinder? The following are the key points for the selection and maintenance of household bean grinders:

1. You can adjust the thickness

When brewing coffee, if you feel that the flavor of the coffee is not as good as you want, it is very important to adjust the grinding thickness. If you feel the taste is lighter, you can adjust the scale fine; if you think there are too many substances extracted, you can adjust the scale thicker. Of course, there are many reasons for affecting the flavor of a cup of coffee, but only the impact of the bean grinder is discussed here.

Especially when choosing a hand bean grinder, a calibrated adjusting screw is necessary, on the one hand, you can know the grinding calibration parameters you are currently using, and on the other hand, there is a clear standard basis for adjusting the grinding parameters.

two。 It can be cut and ground evenly.

According to the type of cutter head, bean grinder can be divided into flat knife, cone knife and ghost teeth. The grinding uniformity of these bean grinders can basically reach a certain level. However, there is a kind of "chopping bean" grinder similar to the principle of the blender, which cannot be cut evenly. The use of this bean grinder results in a difference in particle size and an error in extraction.

"chopping bean" bean grinder:

Basically chopping beans is the use of metal pieces, electrically rotating chopped beans, you can roughly control the thickness of the powder through the speed of the blade, imagine putting the coffee beans on the chopping board and chopping them with a knife.

Advantages of chopping beans: simple adjustment, basic grinding function, cheap

Disadvantages of chopping beans:

1. Inaccurate grinding quality, unstable cooking results: because the blade grinding machine grinds all beans at the same time, the size of the coffee powder may be uneven, because the blade will cut up the coffee beans aimlessly, which means that the finished powder will have coarse particles, which will lead to insufficient extraction, and there will also be powders that are too shredded to lead to over-extraction.

two。 The fine powder mentioned in the first point can block the filter of the coffee machine or cup, or directly penetrate the filter so that there are fine coffee grounds in the cup.

3. The biggest drawback of the chopper is the heat produced during grinding-this heat can cause coffee to taste scorched and bitter, especially if you grind it very fine, resulting in longer contact between the beans and the blade.

Round knife / flat knife bean grinder (Flat Burr):

The cutter head is smaller-it is also a more economical option. The cutter head will make a lot of noise because of its rapid rotation, and the faster it rotates, the lower the grinding quality (the more the knife head will heat the grinding).

Cone knife bean grinder (Conical Burr):

The cone knife grinder is recognized as the best type of bean grinder, and the rotation speed of the cutter head is slower than that of the flat knife, which is not only quieter during grinding, but also more stable. It is suitable for deep baking with high grinding oil or shallow baking with aroma type, because the grinding quality is high and will not clog the filter. And the larger cutter head also helps to stabilize the heat dissipation.

3. It is not easy to generate heat

When grinding coffee beans, the most fear is that the powder comes into contact with the knife head generated by friction, thus affecting the original flavor of the coffee, but usually when brewing at home, unless you grind a large number of coffee beans at once, the knife head is less likely to overheat. However, the above-mentioned chopping bean grinder is easy to generate heat due to friction during grinding, which is not only unable to cut evenly, but also spoils the coffee powder because of the heat, so it is not recommended to use it.

4. Less residual powder and easy to clean

No matter how good the quality of the bean grinder is, the problem of residual powder will occur during grinding, and the residual powder will affect the quality of your next coffee powder grinding. If you are grinding Ethiopian coffee beans now, the next grinding Indonesian coffee will be mixed with Ethiopian coffee, so you need to prepare some Indonesian coffee beans to do the action of "washing beans".

The use of bean grinder in home cooking is usually small and low frequency. if the problem of residual coffee powder in the bean grinder is serious, the residual powder is easy to oxidize and rot in the bean grinder, produce peculiar smell and affect the daily use experience.

How to maintain the bean grinder?

After regularly cleaning the bean grinder, especially after grinding coffee beans with strong aroma, it is as simple as that! The knife plate bean grinder takes care of everything.

In addition, you can also buy soft brushes and blow balls to do basic cleaning. If you want to deeply clean the bean grinder, but do not know how to disassemble it, do not recommend self-research, manufacturers may not accept warranty because the machine has been disassembled, it is recommended to seek professional assistance.

Finally, whether you have a bean grinder or not, it is not recommended to grind the coffee into powder and save it at one time, because the surface area of the coffee in contact with the air is magnified a hundred times, and the aroma will dissipate quickly, even if it is preserved well. So the best coffee is a small amount of grinding, grinding and rapid brewing, so that you can best taste the flavor of the beans themselves.
