How does the thickness of coffee powder affect the taste-common grinding thickness picture

Coffee powder is made from roasted coffee beans, and water (either hot or cold) passes through coffee powder to precipitate aromatic substances, caffeine and other substances in coffee powder and dissolve in water to form coffee liquid, and its solid substances are insoluble in water.

Instant coffee is granulated after evaporating the water from the coffee liquid that has completed the extraction steps.

Therefore, using brewing coffee powder is generally called extraction. There are many kinds of extraction methods for coffee powder, such as pressure extraction (Italian), hand flushing, siphon, cold extraction, ice droplets and so on.

Logically speaking, making instant coffee should be called reduction.

How to make delicious and mellow coffee must be matched by a series of factors:

Coffee beans

If you want to brew a cup of coffee by yourself, in addition to the brewing skills, the most important thing is to choose and buy good quality coffee beans. When buying, you should also pay attention to whether the color and particle size of the beans are uniform. Good coffee beans are not only shiny in appearance, but also have a strong aroma without being mixed with peculiar smell.

Degree of grinding

To do the correct grinding according to the coffee machine used, grinding can be roughly divided into three stages: rough grinding, medium grinding, and fine grinding.

Coarse ground coffee is suitable for filter coffee pot (traditional American brewer), medium ground coffee is suitable for follicular, flannel filter and siphon coffee pot, and fine grinding is most suitable for coffee distiller (also known as water drop coffee maker). And I would like to remind you that the shorter the brewing time, the more detailed the grinding particles should be. Because the smaller the particles, the larger the area of contact with hot water, so the brewing time is shorter. And too fine grinding will make the coffee more bitter, but also easier to block the coffee machine; too rough grinding, it will make less flavor coffee.

Fresh and warm water

97% of the coffee is water, and only water of good quality can brew the original aroma and richness of the coffee. It is best to use filtered water to make coffee. Do not boil the coffee, because boiling water will make the coffee bitter, but also pay attention to the temperature of the water should be slightly lower than 96 degrees Celsius.

The coffee had better not be reheated. When cooking, you should pay attention to only the amount needed for each cooking, and it is best to drink it when it is just cooked. The best drinking temperature for coffee is 85 degrees Celsius.

How to cook coffee beans

First prepare the necessary utensils: a small hand coffee grinder, coffee filter paper, coffee funnel, cup, so that you can make a simple and convenient hand-made coffee.

1. Ground beans

First grind the coffee beans with a mill (the finest grinding).

If there is a shredder at home or a soymilk machine with crushing function can also be used, but the effect is not very ideal, the particles are relatively coarse. If none of these tools are available, it can be achieved with a rolling pin and a panel. Rolling and mashing methods, in short, to make the particles as small as possible.

2. Make coffee

If the coffee powder is ground fine enough, use brewing. Put a piece of filter paper on the inside of the funnel, put a cup of coffee powder (8-10) into the filter paper pocket, to avoid coffee powder leakage, first wet the coffee powder with warm water, warm the cup with boiling water in advance, and then put it under the funnel. Add the right amount of coffee powder according to your own taste.

3. Brewing

With pure water of about 96 degrees (it must be pure water, otherwise it will affect the taste of coffee), pour a small amount of coffee powder clockwise on the coffee powder, fully submerge the coffee powder, wait a while, after the first water is filtered into the cup, continue to pour a small amount of water clockwise. When the coffee liquid in the cup reaches the desired amount, you can close the cup and pour the cup counterclockwise. The amount of water added should be determined according to the amount of coffee powder and personal taste. )

4. Boil

If the grinding particles are still large, they need to be boiled over high heat. Use a casserole or stainless steel pot, heat it with the right amount of cold water, be sure to control the heat, cook for 2 minutes until the oil foam is overflowing, turn to low heat and cook for half a minute, cease fire and precipitate for half a minute, then pour out and filter with filter paper when pouring out.

5. Seasoning

You can add the right amount of sugar and milk according to your taste, or drink it directly.

This method is simple and does not affect the taste of coffee, but we must pay attention to the temperature of brewing water and the temperature of coffee liquid, otherwise it will affect the taste. The coffee beans here had better be freshly roasted and freshly ground at the same time, which can ensure the aroma and taste of the coffee.
