Seven factors affecting hand-brewed coffee

There are differences and similarities. Let me talk about it slowly. First, let me talk about the American coffee machine that your friend said, that is, American-style filter coffee.

Bunn successfully developed the first commercial American coffee machine in 1963. After improvement, it entered the American family in 1967. At that time, the coffee machine in the advertisement was almost the same as the American drip filter in my picture.

The drip filter coffee machine is very easy to use. Even a person who has never made coffee can easily make a cup of American filter coffee. For the following steps, first put filter paper into the filter cup, pour the ground coffee powder into the filter cup that has already put filter paper, install the filter cup with the dripping machine, and add pure water or soft water to the top of the coffee machine (remember not to add tap water, it is too hard. Scale will reduce the life of the coffee maker, be sure to use pure water or soft water with TDS less than 100), set the temperature you want, and when the water reaches the desired temperature, it will be extracted evenly.

Turning to the selection and purchase of American coffee machines, I personally do not recommend that you buy two or three hundred American trickling filters on the Internet, because the American trickling filter produced is either uneven or over-extracted, and it will taste bitter and bitter. It doesn't make you enjoy a delicious cup of coffee.

First of all, the low-end drip filter does not need to use filter paper, mostly such a filter, this kind of filter is easy to let the water flow through the filter quickly, resulting in insufficient extraction. If the powder is ground too fine, it will let the water sit in the coffee powder for a long time, resulting in excessive extraction, and the coffee you drink is easy to have a bitter feeling.

The professional American coffee drip filter uses this kind of filter cup which needs to put filter paper. The advantage of filter paper is that it can make coffee extraction more slowly. For example, if you use a coarse grinded coffee powder, because there is filter paper, it slows down the extraction speed of coffee powder and achieves uniform extraction.

After talking about the water outlet hole in the filter cup, the low-end American trickling filter mostly has only one middle outlet hole in order to save cost, which leads to that the middle outlet hole can only inject water into the middle of the coffee powder in the filter cup, and we know that in order to evenly inject water, we need to evenly inject water from the inside to the outside in order to evenly extract coffee powder, which will not lead to over-extraction of some coffee powder. The phenomenon of insufficient extraction of some coffee powder.

Let's take a look at how the professional American drip filter simulates the brewing process of hand-brewed coffee. You should have found that he has ten holes, that is to say, his outlet holes are evenly distributed over the filter cup. This purpose is to ensure the uniform extraction of coffee powder and simulate the hand-brewing process to the maximum extent.

Professional American drip filtration will also use a more professional thermostat system. We all know that coffee is very sensitive to water temperature. Too high or too low temperature will affect the extraction of coffee flavor.

Nowadays, international cup testing competitions are made with American drip filters, because many American drip filters meet the gold cup standard of SCAA American Fine Coffee Association and can make a perfect cup of coffee.

After talking about the American coffee drip filter, let's talk about hand-brewed coffee. In order to answer the question, I specially patted the whole process of hand-brewing. The pictures are all original.

To make hand-made coffee, first of all, you should have a handy pot. This depends on the individual. Some people like the thin-mouthed pot to follow the Japanese style, while others like the grenade, and follow the American-style fast-flushing genre. No matter how to make it, good taste is the king, and it is in line with your own taste.

The first step is to pour in the ground coffee powder. I use the small Fuji scale 3.5.

20 grams of coffee powder, about one for two.

The first time of water injection, steam with 30 grams of water, evenly from the inside to the outside, the amount of steaming should be as small as possible, slow, as close to the powder layer as possible.

During the steaming process, when the coffee powder no longer expands, it is time to start the second water injection.

The second water injection, uniform circle, from the inside to the outside, do not let the water come into contact with the filter cup wall, because the water will flow down the sink of the filter cup wall, which will cause the extraction.

The third time of water injection, to reach the right amount of water, I used a water-powder ratio of 1 to 15, that is, 300 grams of water.

After 300 grams, stop the water injection and wait for all the drip filtration to be completed in about 20 seconds.

A cup of hand-made coffee is finished.

We have found that the brewing process of hand-brewed coffee is more complicated than that of American coffee machine, so there are more possibilities and uncertainties. This is also the reason why people are keen on hand-brewing. American coffee machine is too stable. Every cup of coffee meets the standard of gold cup, too rigid, not fun, of course, there is no problem in drinking.

The flavor of coffee made by hand is more open, that is to say, you can drink more flavor and the flavor is more delicate, while the coffee made by drip filter has a more compact flavor and can drink less flavor than by hand. This is why it is more difficult to find out a different cup of coffee by triangular cup test during the World Cup test competition, because the water temperature is relatively higher than that of hand flushing by using a trickle filter. The flavor is not so open, and if people who are not sensitive to smell and taste, it is difficult to tell the difference between two beans from the same state. Hand-brewed coffee with the same bean with different methods of flavor performance is also different, of course, its spindle flavor is unchanged, and the production of drip filter is relatively rigid, its extraction can only meet the standard of gold cup, but it is difficult to change greatly, but it is stable. This is the pleasure of making coffee by hand.
