Coffee blending principle how to mix coffee beans

The extraction method, such as hand-brewed coffee, which emphasizes the flavor of origin, usually uses medium-to-deep roasting for coffee beans, but for Espresso, non-re-roasting is not enough to reflect the perfection of Espresso taste. The baking degree of most Espresso beans is in the re-baking stage after the peak of the second explosion. On the one hand, the requirement of such baking degree comes from the extraction principle of Espresso, Espresso.

Ice drop Coffee the latest Coffee knowledge introduction to the principle of Ice brewed Coffee

The principle of ice-brewed coffee is that the coffee itself is compatible with water and is extracted bit by bit by melting ice. The coffee extracted has different flavor according to the roasting degree, water quantity, water temperature, droplet speed, grinding thickness and other factors. Coffee powder is 100% soaked in low temperature and moist, and the extracted coffee has a strong, smooth and rich taste, which is admirable.

Different extraction principles of iced Coffee and chilled Coffee

There are great differences between the two in the way and time of extraction: 1, hot coffee is extracted with hot water higher than 80 degrees Celsius or above 85 degrees Celsius; second, it must be extracted quickly, because too slow coffee extraction will cause miscellaneous smell. the main substance causing miscellaneous smell is tannin, which can be decomposed into pyrosylic acid after boiling, while tannin can be easily dissolved and decomposed in hot water.

Coffee acidity and sweetness the principle of pressure coffee extraction by hand brewing coffee

Coffee acidity and sweetness the principle of pressure coffee extraction by hand brewing coffee

Sweetness and sour A consensus about sweetness and sour is that sour and sweet complement each other. Sweet without sour will appear dull, while sour without sweet will be sharper. As the saying goes, sweet and sour and delicious, this is the truth. In terms of molecular polarity, due to the short extraction time, the sweet substances extracted by the hand filter droplets are usually less than the method pressure, and considering the contact with water caused by the degree of grinding.

Principle of hand-punching extraction of coffee bean grinding

Principle of hand-punching extraction of coffee bean grinding

For example, the thickness of the powder, you can refer to the scale of the bean grinder, the particle size is also more intuitive visually, experienced friends even if changed to the bean mill also have a direct concept of the powder thickness. The amount of powder can be controlled by weighing, the level of water temperature can be controlled by temperature, extraction time and the ratio of water to powder, these are easy to control to be more accurate, so these factors are summarized through continuous attempts and records.

Steaming and pre-soaking are the first stage of the extraction of single hand-brewed coffee and esp. Whether steaming and pre-soaking are sufficient or not directly affects the taste of a cup of coffee. Although they are used in two types of coffee with different production processes, they have a very close relationship and common principles. Steaming and pre-steaming: steaming: refers to the production of hand-made coffee will be hot water light, soft, fast, uniform

4 principles to follow when making a cup of Espresso

4 principles to follow when making a cup of Espresso

(1)The amount of coffee beans must be standard, generally 14-16 g/cup, using high-quality deep-roasted coffee beans. (2)The grinding powder shall be selected with appropriate particle size, not too coarse or too fine. Coffee beans are ground too coarse or too fine to make thick and delicious espresso coffee. When the coffee powder is ground too coarse, the coffee gap in the filter bowl is too large, the resistance to water is not enough, and the coffee flow is too fast, which is easy to cause extraction.

The principle of spot-by-drop hand flushing for segmented extraction testing

It was interesting to see other people doing segmented extraction by hand, and the experiment was the only criterion for testing the truth, so I also came to play with coffee beans: Yega snow coffee hole plus water temperature: 88 degrees grinding: normal hand size: hand flushing the first test: no photo was taken. Draw a picture to show the cup test results: the first two cups are sweet, sweet and sour, fermented; the last two cups are floral and citrus.

The brewing principle of Italian coffee-coffee basics

First, the relationship between brewing time and grinding filling time If the grinding is too fine and the filling pressure is too concentrated, the resistance is too large, the hot water is not easy to penetrate the coffee powder, which will make the extraction time of coffee too long, and the water in the coffee powder for too long will cause excessive extraction.
