The reasons for the balanced flavor of American drip coffee and hand-brewed coffee

Professional coffee knowledge exchange more coffee bean information please follow the coffee workshop (Wechat official account cafe_style)

Starbucks and KFC, including McDonald's, sell black coffee made with American-style drip-filter coffee machines, because the coffee produced by this American-style drip machine has a more stable taste, can produce multi-person portions at a time, is efficient and can be produced quickly, as long as you use boutique coffee beans (coffee with a cup score of more than 80 points) instead of commercial grade coffee beans (cup test scores are less than 80 points). About 70 points of coffee beans) can make a cup of black coffee with good taste, even without sugar or milk, there will be no bitter coffee.

American-style coffee maker

So many people will ask why the American Didi black coffee I drink at KFC or Starbucks only tastes scorched and burnt. I was puzzled before, and it dawned on me when I passed by KFC the other day and saw their billboard.

According to the advertisement, there is no problem with freshly ground coffee and Arabica coffee.

KFC coffee

Why freshly ground, freshly ground coffee is to ensure the freshness of coffee, because the good flavor of coffee is easy to lose, this is also why coffee beans are sealed and stored, when ground into powder, the flavor is lost faster, so it should be ground and drunk.

100% Arabica species are also mentioned in the advertisement. Arabica species are excellent varieties in coffee, because Arabica species have better flavor and sweetness, but because of their poor disease resistance and relatively low yield, it is more complex to grow Arabica coffee. You need to grow good Arabica coffee at a high altitude, so the first one is also higher. While instant coffee is robusta coffee, which has monotonous flavor, high yield, good disease resistance and higher caffeine content, which is 2-3 times higher than Arabica caffeine.

I usually make hand-made coffee in my own shop and sometimes even seven or eight cups a day will not lose sleep.

Because of its good disease resistance, Robusta species grow a large number of robusta coffee in Yunnan and Hainan. Because of good disease resistance, high yield and large market demand, Robusta species are used for instant coffee to drink commercial coffee. The boutique coffee market is dominated by Arabica coffee.

Then why doesn't KFC's American drip coffee taste good? what's the problem?

The coffee beans have been burnt

Looking at the details, we know that the coffee in the picture has reached the level of French baking. at this roasting degree, the good flavor of the coffee has been lost, and if there is a slight mistake in the roasting process, a pot of bitter and astringent coffee will be baked. Some of the coffee beans in the picture have been scorched and there are signs of burns on the surface, which is caused by too much firepower in the baking process and belongs to defective roasting. So of course this kind of coffee won't taste good.

Nowadays, the popular baking degree in the world is shallow baking, moderate baking, urban baking at most, and rarely baking to French baking.

Coffee roasting degree

The third wave of boutique coffee is more in pursuit of coffee flavor performance, pay attention to regional flavor, so the baking degree will be relatively shallow, in order to express the different flavor performance of different coffee producing areas. Coffee shops like Starbucks are representatives of the second wave of coffee culture, mainly deep baking, then drinking with milk and various syrup, in fact, more coffee with milk and sugar, but the coffee flavor is basically impossible to drink.

Blue bottle coffee is one of the representatives of the third wave of boutique coffee.

BLUE BOTTLE COFFEE

Let's start with the American Didi coffee machine.

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.

This is the advertisement at that time.

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.

I recently bought an American Didi coffee machine with a market price of about 2000.

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 when hand flushing, in order to evenly inject water, it is necessary to evenly inject water from the inside to the outside, in order to evenly extract coffee powder, it will not lead to the phenomenon of over-extraction of some coffee powder and 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.

At present, international cup test competitions are made with American drip coffee machines, 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, continue to talk about hand-brewed coffee, make hand-made coffee, first of all, you need to have a handful of pots, this depends on the individual, some people like thin-mouthed pots to follow the Japanese style, others like grenades, and follow the American-style fast-flushing genre. no matter how to make it, good taste is king, in line with your own taste is king.

The first step is to pour in the ground coffee powder. I use a small Fuji single bean grinder to grind 3.5.

20 grams of coffee powder, about one for two.

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

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.

The brewing process of hand-brewed coffee is more complicated than that of American coffee machine, and there are more human factors, so there is more uncertainty, which is why people are keen on hand-brewing because of its uncertainty. And the American coffee machine is too stable, every cup of coffee meets the standard of fine coffee SCA gold cup, too rigid, not fun, of course, there is no problem to drink, you can drink a perfect cup of coffee.
