Why is the coarse ground coffee powder suitable for trickling filter-the common grinding thickness diagram of coffee powder
Let's discuss the thickness of coffee powder and the matching of equipment.
Many bean grinders in the community have different numbers, so I use foods related to daily life to distinguish the thickness.
-
Fineness grinding: flour black sugar powder
Medium grinding: fine sugar
Roughness grinding: coarse sugar
-
Then list the suitable grinding of the equipment.
-
1. Semantic machine: fineness / medium fineness
two。 Grinding cartridge: medium / medium
3. Siphon / hand punch: medium / medium thick
4. Filter pressure: medium / coarse

As a matter of fact, there are no certain criteria for the thickness, which is related to the roasting degree / type of coffee beans. It is just listed for your reference. For example, our ice drop coffee is treated with coffee beans with different roasting degrees and different thicknesses. To achieve the level of strong, mellow, fragrant, not bitter but not sour.
As long as you grasp the previously mentioned guidelines, there will probably be no big problem:
The longer the extraction time, the thicker the beans will be ground, so as to avoid excessive extraction and bitterness. The shorter the extraction time, the finer the beans will be ground to avoid insufficient extraction.
