Qianjie-Hand brewed coffee grinding degree profile

Different bean grinders have different grinding effects, even if they are the same brand and the same model. Different types of cutter head, coffee powder particles have different shapes, different shapes, and different coffee extraction effects. (Some are flaky, some are blocky, some are round)

Different grinder, coffee powder particle size distribution state is different, the distribution of thickness is different, coffee extraction effect is also different. (Some have more fine powder ratio, some have less fine powder ratio)

Coffee grinding is actually a truth.

Use a grinder to grind coffee beans evenly into the right particles so that it brings out the flavor and aroma you want when it comes into contact with the right water.

If you do not eat, you will not taste the fruit. The whole cup of coffee doesn't taste like coffee.)

The fineness of the coffee beans determines how quickly the substances in the coffee dissolve into the water. Because, the same beans, fine grinding state, coffee powder and water contact area than coarse grinding contact area.

(For example, soft white sugar dissolves faster than white granulated sugar, and fine coffee powder dissolves faster than coarse coffee powder.)

The size of the coffee particles also affects the speed at which water passes through them.

(For example, water moves faster through rocks than through fine sand.)

After coffee beans are ground, the thickness in the container increases. Because there are voids between particles.

If the quality of your grinder is not good enough, it is possible to grind out particles of different sizes. When brewing coffee, different coffee particles dissolve at different speeds, which easily leads to uneven extraction.

When the ground particles become smaller, the overall surface area of coffee powder in contact with water will increase, the coffee powder layer will become thicker, the same water (the same temperature, the same amount of water, the same injection rate of water) will pass through the particles slower, the contact time between water and coffee particles will become longer, and the extraction rate will become higher.

Knowledge points: the thickness of coffee powder, related to brewing coffee when the release of coffee ingredients, how fast. Generally speaking, the thickness of coffee powder can be divided into five grades: very fine powder, fine powder, medium fine powder, medium powder and coarse powder.

In brief: Qianjie is a coffee research center, happy to share knowledge about coffee with everyone, we share it without reservation only to let more friends fall in love with coffee, and there will be 3 low discount coffee activities every month, because Qianjie wants to let more friends drink the best coffee at the lowest price, which is also the purpose of Qianjie for 6 years!
