The key to making a good cup of coffee: A. It is necessary to have a very good raw material for coffee, namely coffee bean B. There should be good and suitable coffee equipment C. People who make coffee should have the correct method of operation. one。 Coffee knowledge the two common varieties of coffee in the market are Arabica Coffee and Robesda Coffee. In terms of growing environment, Arabica coffee grows at a higher altitude.

But in terms of the principle of coffee extraction, it's all the same. The core process of the extraction principle is: (1) grind coffee beans to increase the surface area of coffee in contact with water; (2) fully soak coffee powder in aqueous solution and hydrophilically dissolve coffee essence; (3) separate coffee solution and coffee grounds.
2014-10-09 Coffee knowledge boutique caffeine coffee extraction methodsSteaming, which is often expressed as Bloom in English instructions, refers to the preparatory action of wetting a small amount of hot water evenly on the surface of coffee powder during hand flushing before formal water injection. There are two purposes of steaming: first, to release the gas in the coffee particles, mainly carbon dioxide. Generally speaking, the closer it is to the baking time, the more bubbles usually occur during prepreg. And the baking degree is deeper.
2016-01-19 Steaming extraction coffee key Italian time hand flushing steaming English usageNow many coffee students and coffee makers in domestic coffee shops believe that the key technology of Italian coffee production is the production of milk foam and coffee flower. But the most important thing about Italian coffee is the extract of Espresso.
2014-07-11 Espresso Espresso coffee extraction extraction stepsThen the factors that affect the extraction quality are roughly as follows: the size of the grinding powder, the amount of powder, the water temperature (the first two are a whole powder heap density), the convection (or pressure) of water, the whole time of extraction, and the ratio of coffee powder to water. What is insufficient extraction and what is excessive extraction? To make it easier to understand, let's give a magnification.
2016-04-20 Hand brewing coffee what extraction insufficient excessive then influence qualityWhat is variable pressure technology: at any time to achieve the specified pressure value, and can remain stable, again changed to the specified pressure value can remain the same, is the real variable pressure. If it is only an uncontrollable or unstable variable pressure during the extraction process, it is not a mature variable pressure technology (for example, the pressure of the drawbar machine cannot be controlled from beginning to end and changes all the time, such as Yang.

In order to understand gold cup extraction, we must first understand the concept of extraction rate and concentration. Extraction rate: the weight of dissolved coffee ingredients as a percentage of the total weight of coffee powder used. For example, when we use 18 grams of coffee powder to brew coffee, there are actually only 2.7-4.3 grams of coffee.

2014-12-31 Coffee machine about making Italian coffee variable pressure what is technology anyIn the coffee training class, the exchange, discussion and summary of extraction are in full swing. The following is the teaching summary of the trainers in our school. Coffee extraction is like doing an experiment, controlling the change between solvent (water) and solute (coffee) under environmental variables. How to dissolve the effective substances in coffee according to demand under appropriate conditions is the tireless work of all coffee lovers.
2015-01-08 Coffee Common sense Grinding extraction rate proportion concentration relationship training course courseThe relationship between roasting degree and extraction rate when brewing coffee: the shallower the roasted coffee bean is, the harder the fiber is, and the harder it is to dissolve the flavor, so it is necessary to brew it with higher water temperature, longer time or finer grinding degree, so as to avoid insufficient extraction. On the contrary, deep-baked beans should be brewed in a lower water temperature, brewed in a shorter time or coarsely grinded, so as to avoid excessive extraction. Understand and put what you have learned into practice.

2015-11-23 Coffee extraction terminology science interpretation must-see knowledge pointsCoffee contains a variety of ingredients, extraction does not extract all of these ingredients. Generally speaking, in the case of a certain amount of powder, the extraction amount of soluble components is related to the thickness of grinding and the extraction time. The finer the grinding and the longer the extraction time, the more substances will be extracted. And vice versa. When making a coffee, choose the appropriate extraction method and the degree of grinding is this cup of coffee.
