Qianjie-introduction of hand brewing coffee utensils and grinding degree

Each coffee utensil has its own suitable degree of grinding, so we don't use whatever degree of grinding we want. As mentioned above, the coffee powder is too coarse or too fine to make coffee, that is to say, the most suitable grinding degree is medium to medium roughness.

The following is the relationship between the grinding degree of coffee powder and the extraction method:

1. Suitable for fineness grinding: Turkish copper pot, mocha pot, espresso machine.

2. Suitable for medium grinding: filter paper dripping filter, flannel dripping, plug air kettle (also known as siphon kettle).

3. Suitable for roughness grinding: dripping coffee machine, dripping filter pot

Generally speaking, a good grinding method should include the following four basic principles:

1. The degree of grinding suitable for cooking method should be selected.

two。 The temperature produced during grinding is lower.

3. The powder should be uniform after grinding.

4. Grind before cooking.

No matter what kind of grinder is used, it is bound to generate heat by friction during operation. However, most of the fine substances are highly volatile, and the heat of grinding will increase the speed of volatilization, allowing the aromatic alcohol to be lost in the air first.

After grinding, the cell wall of coffee beans will completely disintegrate, which means that the area of contact with air will increase a lot, all lines of defense to protect freshness will be completely removed, and the rate of oxidation and deterioration will become faster, which will make the coffee lose its flavor within 30 seconds to 2 minutes. Therefore, Qianjie strongly recommends: do not buy coffee powder, it is best to buy coffee beans, and grinding before drinking, grinding should be brewed as soon as possible.

Necessary hand flushing equipment: 1. Bean grinder 2. Electronic scale 3. Filter cup 4. Hand flush pot 5. Thermometer / timer

Knowledge: choose electronic scales that can accurately measure the weight of 0.1 grams of coffee beans.

In short: Qianjie is a coffee research hall, happy to share the knowledge about coffee with you, we share unreservedly just to make more friends fall in love with coffee, and there will be three low-discount coffee activities every month. The reason is that Qianjie wants to make more friends drink the best coffee at the lowest price, which has been Qianjie's tenet for 6 years!
