Immersion method
French press
Directly inject boiling water into the coffee powder and steep it for a few minutes, then use a metal plunger to filter it. This type of equipment is also often used to make black tea. It is widely recognized in Europe and the United States as a household coffee extraction equipment. This extraction method is very difficult and does not require special skills. It can be said to be suitable for beginners. In this method, the oil content of the coffee is extracted without filtering, so the taste is very strong, but because micron powder will also enter the coffee, it will affect the taste to some extent.
Siphon pot type
This method mainly uses the changes in air pressure of the roasted type to extract coffee. The siphon pot is an extraction device with many enthusiastic fans due to its gorgeous appearance and visual effects. It is also well-known for this. Because extraction is generally performed in a high temperature zone, this method can extract coffee with a strong aroma. However, the maintenance and care of siphon pot is more difficult. This method is known as Turkish is coffee or Eve is coffee extraction method. He requires that water and very small particles of coffee powder be mixed together and heated until boiling, and then extracted. The corresponding drinking method is also very unique. Without filtering, pour the coffee powder directly into the cup, wait until the powder settles, and then drink the clear layer. The coffee extracted using this method is also more concentrated.
Italian coffee pot style
This is a direct fire extraction method that uses the vapor pressure of boiling water to extract coffee. The Italian coffee pot is a famous extraction device that is a must-have for every Italian household. Because it uses water and steam pressure exceeding 100 degrees Celsius to extract coffee, it can extract coffee with a higher concentration.
Penetration method Filter paper filtration
It is a method of extracting coffee by placing filter paper on the filter cup and then filtering the coffee powder layer. The coffee is clarified as it passes through the filter paper and coffee powder layer, turning into a clear liquid.
Metal filter filter type
This is a method of drip filter extraction using a metal filter. The advantage of using a metal filter instead of a paper filter is that it can extract the oil in the coffee powder. In addition, unlike disposable filter paper, because the metal filter can be reused, it can be said to be a more environmentally friendly extraction method. However, although this method reduces the amount of micron powder, it will still be extracted, so it is not suitable for those who do not like the rough taste brought by micron powder.
Flannel cloth filter type
This is an extraction method that uses flannel , a soft fabric as the filter cloth. The sticky texture can be said to be the unique characteristic of coffee extracted using flannel cloth filter type. However, you need to pay attention to the cleaning and storage methods of the flannel itself.
Italian espresso style
This method requires grinding the powder to a very small particle size and compacting it, and then extracting it by applying pressure. The concentration of the coffee extracted using this method is nearly ten times higher than that of drip coffee. Extracting espresso requires a high degree of skill and in-depth understanding of extraction, as well as expensive machinery, so it is not recommended for home use.
Hybrid
Aeropress
Aeropress consists of two large cylinders, which overlap like syringes. It is an extraction method that squeezes out coffee. In order to use air pressure for extraction, coffee powder with smaller particle size must be used, and the extraction time is also shorter. As a common extraction method in Northern Europe, Aeropress has now developed into a popular extraction method that can hold world competitions alone.
Smart cup style
Smart cup looks like a filter cup, but there is a valve under the cup that can store hot water in the filter cup. This is an extraction method that combines the soaking method and the penetration method, so it is considered to be a relatively new extraction method designed for those who like the texture brought by the soaking method but do not like micron powder.
