After you want to have a good cup of coffee, you will choose your favorite coffee utensils carefully, but you may not buy a bean grinder, but choose to buy freshly ground coffee powder directly or let the merchant grind it on your behalf.

●, good coffee is freshly ground.

As a kind of agricultural product, the freshness of coffee beans is very important. After roasting, the coffee beans will swell, fill the body with small pores and constantly release carbon dioxide. As the coffee beans release gas, the volatile aromas in the beans continue to be released, which will soon lose the charming aroma of coffee.

So there will be an one-way exhaust valve on the coffee bean bag, which is designed to exhaust the gas released by the coffee bean without letting the air into the bag to oxidize the coffee bean.

The function of ● Grinding

We grind the coffee beans into powder and cut the coffee beans into thousands of small particles in order to increase the surface area of coffee beans and increase the extraction rate. After the coffee powder is ground, the volatilization of the gas will be accelerated and the flavor will be fleeting. In a coffee shop, coffee powder is often thrown away if it is not used for half an hour.

Good coffee beans will not be ground into powder for sale in advance, for example, we will only grind them for you after you buy them. Even some strict merchants will refuse to grind the powder for you.

What should ● pay attention to when grinding coffee beans?

1. Thickness and fineness

Different grinding thickness means that the surface area of coffee beans is different. The finer the grinding, the larger the surface area, the higher the extraction rate, and vice versa. Therefore, different extraction methods should use different degrees of grinding:

Pressurized extraction: espresso-the finest, refined salt

Filter extraction: hand brewed coffee-medium, granulated sugar

Immersion extraction: pressure kettle-the thickest, sea salt particles

two。 Evenness degree

We need to grind the coffee powder into particles of the same size as far as possible in order to find the reference basis for extraction. For example, the bigger the particles, the higher the water temperature and the longer the time. However, if the particles are large and small, the extraction will become inconsistent, and we will not be able to get good coffee with uniform extraction.

● correctly chooses bean grinder

Working principle of bean grinder

The blade of the bean grinder consists of a moving grinding wheel and a non-moving contact surface in which the coffee beans are ground. By adjusting the distance between the grinding wheels, the thickness of coffee particles can be controlled. As long as the coffee powder is ground to the particles of the distance between the grinding wheels, it will fall into the powder bin below and will not be further ground.

Why can't you use a cooking machine (or crusher) to grind coffee beans? Because grinding can't! Jun! Yun! The structure of the cooking machine is that the metal blade is connected to the motor, the coffee beans are broken by rotating force, and the coffee beans are cut repeatedly. If you want to get finer powder, it can only be achieved by grinding for a longer time. Because there is no powder cartridge design, there is a chance to continue grinding no matter how far it is ground, resulting in the coexistence of very fine powder and very coarse particles.

● hand bean grinder is not as professional as electric bean grinder?

The working principle of hand bean grinder is the same as that of electric bean grinder, so there is no need to worry about being unprofessional. Many people like to use it because of its hands-on participation. It is said that Beethoven put sixty coffee beans into the grinder every morning to enjoy the aroma and experience the fun while grinding the coffee.

Most hand grinding machines use ceramic core grinding, which does not produce a lot of heat to burn coffee powder and can be washed with water.

Should ● choose a hand or an electric bean grinder?

How much coffee do you drink every day? How many people are there to drink?

The hand grinder is more suitable for 2 people using 1 Mel, and only drinks 1 Mel 2 cups of coffee a day.

2. What utensils do you use to make coffee?

Manual bean grinders are suitable for hand-flushing, French pressure and other coffee utensils, but if you use pressurized extraction appliances such as mocha pots and semi-automatic coffee machines, you should choose an electric bean grinder.

Qianjie coffee: Guangzhou bakery, the store is small but a variety of beans, you can find a variety of unknown beans, but also provide online store services. Https://shop104210103.taobao.com
