When making Espresso filling powder, ideally, the coffee powder is evenly distributed before pressing, and then pressed. The coffee powder has a flat surface and uniform density, so that the water extracted from the coffee can pass through evenly. Extract all the aromatic components from the coffee powder. The coffee powder is pressed too loosely. After the extraction, there must be a perforated hole in your pressed powder. If the pressure is too tight, pressed powder
2015-11-07 Italian style Coffee Powder pressing filling correct method cloth Powder manipulation production EspWhy do you use a powder press? baristas all know that when using an espresso machine, the hot water is brewed at about 9 atmospheres (of course, this is not a fixed value, there are 12 atmospheres or more), and the pressure is very high. When the water penetrates the coffee cake, the water is inert. What is inertia, that is, water penetrates through the weakest part of the coffee cake

Xiaobian sorted out several commonly used coffee utensils, each applicable to the grinding degree of coffee beans, to collect quickly! Before classifying the degree of grinding applicable to all kinds of coffee utensils, there are several points that must be paid attention to: 1.

At this point, you need to increase the amount of powder (to get more concentrated dose) to enhance the concentrated flavor of the milk coffee. On the contrary, pure black coffee or small-dose milk coffee need to reduce the amount of powder. Milk coffee in many boutique cafes, strong
2016-07-28 Italian Coffee extract three variable concentrate Oil blend Coffee BeanThe horizontal axis is the extraction rate. The vertical axis is the concentration. Assuming that the coffee powder is 20g, the coffee liquid obtained when the concentration is 1.35% and the extraction rate is 18%, in the gold cup range, should be 20*18%/1.35%=266g. The concentration is 1.35%. The extraction rate is increased to 22%. The coffee liquid obtained is 20*22%/1.35%=325g. The extraction rate is 22%. The concentration will be 1.15% the result coffee liquor is 20*22%/1.1

The article will mention several questions: (1) the concept of gold cup criterion; (2) the relationship between extraction rate and concentration; (3) knowing the extraction rate, it is meaningful for us to adjust the grinding degree and powder quantity every day, and then we can make it better.

Extraction and extraction equilibrium s the reasonable extraction range is set by ebf, and the extraction results are tested by tds. Combined with the grinding scale and the ratio of gouache to powder to modify the results, it is the quality control system of most knowledge-based barista when making espresso. Under this seemingly rigorous operation process, will there be loopholes? Extraction uniformity is a monitoring blind area which is easy to be ignored.

Students who have previously taken the Level 1 will switch to the Professional course if they continue to study.

I have posted in my photo album, a teacher of a Korean coffee champion, a contact person in charge of world events, a world champion, together with me, look very different. In fact, Michael Philips takes the trouble to explain to others the relationship between extraction rate and regulation. I don't seem to care about this picture.
2015-11-05 Coffee in fact is difficult to make needs knows one thing extraction this photo speaking ofThe degree of grinding should be proportional to the extraction time. The roughness of coffee grinding will directly affect the extraction time and extraction rate. The finer the coffee is ground, the denser the powder layer is, the more coffee powder particles are in contact with hot water, the greater the extraction resistance, the easier it is to prolong the extraction time and improve the extraction rate, and it is easy to over-extract. On the contrary, the thicker the coffee is ground, the larger the gap in the powder layer is, and there are fewer.
2015-03-13 Coffee beans correct grinding methods techniques degree extraction time straighteningWhat is the law of gold cup extraction; how to adjust the extraction rate and coffee concentration; questions often misunderstood by baristas. 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.

Let's start with a question: what on earth is a cup of coffee? Simply put, when the water passes through the coffee powder, it dissolves and brings out some of the soluble matter in the coffee powder, and then we get a cup of coffee. That is to say

It takes about 2 to 3 minutes to make. Using cold extraction to make cold-soaked coffee Cold Brew refers to coffee extracted by soaking coffee powder in cold water less than 5 ℃ for a long time, which takes about 8-12 hours.
