Types of coffee brewing and utensils

Filter paper

Place a filter paper in the filter cup, put the coffee powder into it, pour into the hot water and extract. This is the most popular method of coffee extraction. The device is easy to operate, but needs to be practiced to achieve a consistent taste.

The grinding medium suitable for dripping paper is medium and fine.

Flannel

The extraction mechanism is the same as that of dripping paper, but the filter is made of cloth. Nell is the abbreviation of "flannel", which refers to the velvet woven fabric. Because the contact time between coffee powder and hot water is long and the temperature is maintained, it balances the extraction of coffee ingredients such as bitter and sour taste, and can bring out the original aroma of coffee.

The fiber of the cloth will capture fine particles and extract a large amount of oil, resulting in a mellow, full-bodied taste and smooth texture. The difficulty lies in cleaning and storing flannelette after use.

The appropriate degree of grinding of the hand while sleeping is medium grinding.

* in hand cooking, in addition to paper and flannel, there are a variety of filter materials, such as metal, lava and other permeable rocks and ceramics.

Siphon kettle

Use glass flasks and funnels to move and extract hot water using vapor pressure. The attraction is so great that the hot water rises when heated, or the extract decreases when it stops. Due to the use of hot water, it is easy to produce bitterness.

It is less affected by the barista's skills than hand flushing, and it is an extraction method, and if you learn how to operate the device, its taste will be stable.

The suitable grinding medium for siphon is medium and slightly coarse.

French pressure kettle

Put the coffee powder into a press container, pour boiling water into it, and then use a metal filter called a plunger to press down to extract it. A large amount of coffee oil was extracted to make it have a strong flavor. The extract is slightly turbid.

The extraction method is becoming popular in Japan because it can easily produce a stable taste, and the equipment is easy to carry and is very suitable for outdoor use.

The grinding medium suitable for the pressure kettle is medium grinding.

A similar system also has a pneumatic device, which is shaped like a syringe and can be pressed and pulled out by air pressure. It is said that simple espresso can be made.

Ice drop

Because it is extracted with water (at low temperatures), it takes time, but it tastes mild and moderately bitter. If you use deep-roasted coffee beans, you can make coffee with low acidity and easy to drink.

Good grinding of dripping water is fine grinding.

American coffee machine

Using the same extraction method as dripping paper, you can easily extract it with the click of a switch. I can always give a taste, but it's not interesting because I can't change it.

Suitable for coffee machine grinding is medium and fine grinding.

Italian coffee maker

There is a direct injection coffee machine that directly uses saturated steam and an electric espresso machine that can be extracted at one time at high temperature and high pressure.

The direct stove is cheap, easy to carry and suitable for outdoor use, but it does not turn into thick espresso like an electric stove and does not produce foam (foam). The electric type can also cause blistering (foam), which is said to be more abundant but less sweet. Sell all kinds of machines, some of which require some skill.

The finest grinding suitable for espresso machine is ultra-fine grinding.
