When it comes to the oil in coffee, what do you think of?

Generally speaking, the first impression should be the large layer of "Crema" floating above the Italian concentrate. It is often said that that layer of Crema is an important source of aroma and taste, but there is a sentence in the Coffee equation of Taguchi:

"in my experience, removing the bubble ESPRESSO can greatly reduce the unpleasant taste. "

-- Danbu Xingbo

As far as ESPRESSO is concerned, there is nothing wrong with the saying that "Crema is a very important source of aroma". It has to be said that the aroma and impact of ESPRESSO without foam is not as good as that of normal ESPRESSO.

But!!!

Skimming off the ESPRESSO of Crema, it does greatly improve the ease of entrance, makes people feel clearer in the mouth, and does not have the strong sting bitterness and miscellaneous feeling of the general ESPRESSO entrance.

We must first know that the Japanese are very sensitive to "irritation" and "astringency" in their sense of taste. what they care about is the "taste" they drink into their mouths, not so much about the "aroma" when they get close to their noses. So although Crema foam can retain many aromas that are easy to spread during extraction, it does not add much to the taste preference of the Japanese. Instead, Mr. Dan analyzed a high concentration of caffeic acid, chlorogenic acid and other substances from the foam, which will bring astringency to the senses.

So if we put our hands on it, should it have the same effect?

Coffee in the process of extraction will occur the so-called "emulsification" role, if the extraction method is appropriate, the emulsified oil-water mixture shows a "oil-water" state, oil can also retain a large number of water-soluble but highly fugitive flavor.

However, causing "astringency" and "throat-biting bitterness" and even "burning taste" are unfortunately fat-soluble substances, although coffee fat is good for flavor, it is by no means the more the better. Coffee Taste | Coffee tastes bitter and astringent. How to understand the tea and dryness in coffee?

Oil brings coffee with sweetness, taste and mellow aroma. There must be fat, or it may have the same amount of lactose as a cup of skim milk, but there is a considerable difference in sweetness between nonfat and full fat. But another certainty is that if the oil is allowed into the coffee liquid without control, there will of course be the smell caused by improper extraction. If there is not enough fat, it will cause a thin taste, but allowing too much emulsified oil into the coffee liquid will also cause a bad flavor.

Therefore, how to balance the taste and flavor of oil extraction point through proper extraction is also a knowledge, and it is the most difficult to adjust the so-called "parameters" to control.

To this end, the editor thought of a very "simple and rough" method-the use of fine powder.

The reason why Italian concentration is rich in oil and rich flavor, very fine ground coffee powder is one of the keys. When coffee beans are ground finely, the area of contact with hot water will be greatly increased, so that the oil in coffee cells can be easily released and wrapped in water-soluble flavor substances. Excessive lipids can also be accompanied by impurities to make coffee cloudy. Filter paper can absorb oil to a certain extent, but it is obviously not possible to grind coffee powder into Italian thickness for hand flushing, so we added another tool: French kettle for coarse filtration.

The utensils used are as follows: French kettle, mixing rod, V60 filter cup & filter paper, sharing pot

First of all, it is called good coffee beans, this is a coffee that won the championship of Ethiopia's TOH (the Taste Of Harvest) in 2017-Sakui, and today it uses Sunshine Sakui 2.0 of the new production season in 2018, which comes from the mountain spring treatment plant in the core production area of Humbera. For more information about Sakuran, you can take a look at the story of Sakuran here. Xida Mohambela Sakuran 2.0, Ethiopia, in the new 18-year production season.

Boil the water and prepare the mixing rod, French kettle, V60 filter cup filter paper and sharing pot.

Gouache ratio at 1:14, water boil, grinding, grinding using Italian concentration of the same thickness.

Pour freshly boiled hot water into the kettle, pour in the coffee powder, stir immediately with a stirring stick for 10 seconds, cover and soak for 20 seconds.

Break the slag under the pressure (because the fine powder requires a lot of strength), pour into the filter cup to filter the very fine powder and absorb part of the oil, and then complete!

We make use of the characteristics of high extraction rate of fine powder and fast release of flavor, together with stirring and legal pressure, we can extract flavor and oil in a short time, strengthen the aroma and alcohol thickness of Huakui, and filter through filter paper. very fine powder, oil and impurities will be absorbed and isolated.

A cup of coffee made in this way, with complete flavor and long-lasting aftertaste, is very sweet and clean, even if it is completely cold, it will not be cloudy. The point is that it does not require any means to make a good cup of coffee!

The above operations are suitable for almost any type of coffee beans except deep-roasted coffee, and the grinding degree and water temperature do not need to be adjusted. For medium-deep roasted coffee, you only need to shorten the stirring or soaking time by a few seconds. In addition, if you feel that the taste of the coffee is too strong, the ratio of water to powder can be adjusted to 1:15.
