HOW TO CHOOSE A COFFEE GRINDER - which coffee grinder is better, how to grind coffee correctly

Grinder types are determined by the grinding systems.

In mechanical models, the degree of grinding is regulated by a screw - you can make it a little larger or smaller. But it will still be a fine grind. You can brew such coffee in a French press with a fine grinding filter.

If you do not feel like turning the mill in the morning, it is better to choose an electric millstone type coffee grinder. In its container for grains there are two millstones with an adjustable distance between them. On it, you can finely adjust the degree of grinding: fine into dust, medium and coarse.
In a knife (rotary) type coffee grinder, the grinding of the beans often does not change. Therefore, the powder is not uniform. This can be seen if you shake the container with it: fine dust settles on the walls, large pieces in the middle, medium ones on the sides. With this grinding, the drink turns out to be watery.

How to grind coffee correctly

If you hold the "Start" button in the rotary coffee grinder for a long time, the coffee bean will burn and will taste bitter. Part of the reason for the bitter taste of the drink is related to the aging time on the knives of the coffee grinder. The higher the speed (over 200 W), the more likely the grains will overheat. Therefore, interrupt the operation of the machine at short intervals and check the degree of grind.

Delonghi KG49 has an optimal power of 170 W

To avoid bitter disappointment, choose knife models with a power of 150-200 watts. Their knives must be removable. Otherwise, an unpleasant aftertaste cannot be avoided. The coffee stays under the knives and is difficult to clean. In the future, this affects the taste of the drink of the next grinding.

What can you grind in a coffee grinder?

In addition to coffee, you don't need to grind anything else in it. Nuts and cereals for baby food leave a smell that spoils the taste of coffee. In addition, particles can enter the motor.

Knife grinder: how to choose and not go wrong

The essential oils in ground coffee oxidize within half an hour after grinding. After that you drink a drink that does not invigorate. Therefore, grind exactly as much coffee as needed at one time:

6-8 grams per cup of espresso;
up to 70 grams for two people;
70-100 g for the office.

"Baby" Gorenje SMK150B is designed for 36 g of coffee beans

What a good rotary coffee grinder should have

Pulse mode. The harder you press the button, the harder the engine runs. Use for green coffee beans.
Grinding adjustment is a rarity among rotary grinders. You can set the type of coffee grind to your liking: fine, medium or coarse.
Auto-lock. The appliance will not turn on while the lid is open.
Overheat protection. The unit will shut off automatically when the engine is hot.
Bowl tilted. Manufacturers assure that coffee is ground more evenly in it.

Choosing a grinder mill type

In units of the millstone type, protection against bitterness is provided: the crushed powder immediately falls into a separate container.

There are two things to consider when choosing a good grinder.

Rotational speed should be within 500 rpm. Otherwise, the grains will not grind well.
Tank shapeinto which the ground coffee is poured.
- In the cone, everything is ground to the last grain.
- In the cylindrical grain particles remain along the hopper rim. It needs to be shaken to grind everything without residue.

There is no point in choosing a grinder with a large bean container. Even well-packed beans lose flavor in three to four weeks, and even faster in a leaky coffee grinder.

To choose a good burr grinder, pay attention to its additional functions.

Dosage of coffee portions.To grind grains into 2, 3 or 10 cups, you do not need to calculate the proportions, it is enough to set the regulator to a suitable division.
Auto-lock. The burr grinder has a double lock. The appliance will work when you close the bean compartment lid and insert the ground coffee hopper correctly.

Which grind is best for a coffee machine

Have you ever seen a barista with a cheap rotary coffee grinder in hand? And you will not, because the uniformity and degree of grinding of coffee for a carob coffee machine is one of the conditions for preparing a classic espresso.

When shallow, the water almost does not pass through the coffee and the drink turns out to be too strong. It tastes bitter.
If it is too coarse, the water passes too quickly and the coffee does not have time to give off its taste and aroma.
The grinding is selected correctly if the coffee maker dispenses 30 ml of aromatic drink in 22-28 seconds.

If the description of the coffee indicates sourness in taste, but you feel bitterness in the prepared coffee, you need to grind it coarser. When the drink is sour, change the grind to a finer one.
