Qianjie-Hand brewed coffee tutorial, grinding degree introduction

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 sugar, 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. Water moves faster through stones 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. This is just like how we cook meat, some big pieces and some small pieces. Small pieces of meat are cooked, and large pieces of meat are still raw. If you want the meat cooked at the same time, cut it into equal pieces.

The thickness of the conventional hand-brewed coffee powder is medium and fine, subject to the thickness of fine granulated sugar. Of course, some friends like it fine.

brewing method

1. After boiling water, warm the props first. Pour the water from the measuring cup into the mug to preheat the cup.

2. Fill funnel with filter paper, add coffee powder, surface smooth.

3. Slowly pour hot water over the surface of the powder until the water drops below, and let stand for 20 to 30 seconds.

4. After stewing, start to rinse by hand, slowly draw a circle from inside to outside in a spiral way, and pour hot water.

5. When the extraction volume reaches 200ml, separate the hand funnel from the measuring cup (even if there is still water).

6. Pour out the preheated hot water in the cup and pour in the filled coffee (in case of overheating of the cup handle, be careful to use insulation to prevent burns).

Knowledge point: hand-brewed coffee is made by hand with a single variety of coffee beans from a single origin, and those who are particular even roast and grind their own beans.
