Correct understanding and use of coffee utensils and grinding degree

The degree of grinding of coffee varies with different utensils, for a more comprehensive understanding, including many students who are new to coffee utensils often ask questions about this question.

Xiaobian sorted out several commonly used coffee utensils, each applicable to the grinding degree of coffee beans, to collect quickly!

Before classifying the degree of grinding applicable to all kinds of coffee utensils, there are a few points that must be noted:

1. It is not recommended to buy pre-ground coffee powder directly.

2. It's really not good to grind it fine.

Please do not use the coffee bean grinding machine to grind whole grains and other grains.

Grindability of hand punch pot: moderate

If the coffee powder is too thick and the hot water flows too fast, it is difficult to extract the aromatic substances from the coffee. If the coffee powder is too fine, the filter is easy to clog, resulting in water and powder soaking time is too long, water flow in the powder layer can not flow evenly. Resulting in uneven extraction and excessive extraction, coffee will appear bitter, astringent taste. So hand-brewed coffee is suitable for moderately ground coffee powder.

Personally, I think there is a small principle of hand punching--

When the flow is kept to a minimum, water can be injected from the middle of the layer, creating uniform bubbles rather than flowing around from the surface of the layer. Only in this way can we ensure uniform extraction.

What is moderate grinding? the general metaphor is granulated sugar. To be more specific, when you pinch your fingers, you can see that the coffee is polygonal, not flour.

Grinding degree of siphon kettle: moderate

Generally speaking, the extraction time of the siphon pot is about 1 minute and the temperature is about 92 degrees.

If the coffee powder is too fine, it will not only extract too much, but also clog the catheter when the coffee liquid is refluxing. If the coffee powder is too coarse, it will make it difficult to extract aromatic substances still hidden inside the particles, unable to touch and extract with hot water, and the brewed coffee will not have enough aroma. (the Belgian pot is the same) so generally speaking, it is also moderately ground, about the same fineness as hand punching.

Grindability of French kettle: medium and coarse

Because the pressure pot uses the most direct principle of coffee extraction-soaking + filtration. So that the coffee extract of oil and aromatic substances can smoothly pass through the filter, unhindered. So need medium coarse grinding, otherwise the coffee grounds will pass through the filter hole, so that the coffee has a muddy taste. And too fine powder will lead to excessive extraction and bitter taste.

What is medium coarseness, is a little thicker than the hand, is also a clear polygon particles, do not be so thick as to see a large round bean surface.

Grindability of Italian machine: fine

In the process of brewing coffee with an Italian machine, the coffee powder has to withstand high pressure and high temperature, so the powder must be fine and pressed powder should be uniformly pressed so that the coffee powder can block the water pressure and extract evenly. Otherwise, it will spurt out.

If the coffee powder is too fine, the extracted coffee will be more bitter and have dark brown fat. If the coffee powder is too thick, the extracted coffee will tend to turn sour and the fat will turn cinnamon. Fortunately, the Italian machine has a standardized numerical reference, and the grinding degree needs to meet the requirement of "20-30 seconds extraction 60ml" (double powder bowl). If it is too fast, it is thick, and if it is too slow, it is fine.

Turkish coffee grindability: very fine

Because Turkish coffee is boiled and drunk with dregs, the finer it is ground, the better. It looks like flour. In this way, the fine powder can be suspended in the liquid, making the taste appear mellow and sticky. Just like making secret medicine, cook it with a gurgle.

As the oldest way to drink coffee, it really has its charm. Remember that the leftover coffee grounds can still be used for divination.

You ask: how to adjust the thickness?

The hand bean grinder generally has a screw structure, the electric bean grinder is simple, but there must be a scale.

Nani?!

Your electric mill has no scale? Is it like this. ?

▼▼

This. It can be called a bean chopper!

It really can't adjust the scale because it's not designed for coffee grinding, so it doesn't conform to the basic principles of coffee extraction.

Both white sugar and powdered sugar have fineness, not to mention coffee beans.
