Al's Rule of Espresso
Al Critzer's understanding of Espresso extraction has now become the most common Espresso concept in Europe and America. Take the result of 30cc/ 30sec to get a perfect cup of Espresso as the starting point. These two values depend on the beans, of course, and differences in baking methods, baking degrees, and recipe proportions naturally lead to changes in the reference point. Extraction quantity and extraction time mutually interact

What is the relationship between roasting degree and extraction rate when brewing coffee?
The 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.

The main factors affecting extraction by bean grinder are the following four kinds of coffee tasting coffee.
There are four main factors that affect the extraction of bean grinder: uniformity: the coarser coffee particles are more likely to be underextracted, while the finer particles will be overextracted in advance, so the coffee powder with a larger span of grinding thickness is produced. The more turbid and irritating smells can be tasted. On the other hand, the coffee powder with the same size and similar shape is used to extract the coffee powder, and the taste is

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.

Processing methods of coffee beans with low caffeine
CO2 low-caffeine treatment and other low-caffeine treatments are described as follows: at present, there are three ways to remove caffeine from coffee beans: 1. Water treatment can remove 9496% of the caffeine. 2. Chemical extraction method, early use of chloroform (Chloroform) and benzene (Benzene) as solvents to extract caffeine, and later understand that these chemicals cause cancer, and then gradually become other low-hazard chemicals.

The source of astringency in coffee what is the content of tannin in coffee?
Tannin coffee tannic acid coffee contains a variety of ingredients, extraction is not to extract all of these ingredients, there is usually such a rule: if the amount of coffee powder is fixed, the amount of soluble components extracted depends on the degree of grinding and time. The finer the grinding degree of coffee powder is, the longer the extraction time is, the more ingredients will be obtained. According to the experiment, if the quantitative coffee powder can be extracted

Basic knowledge of espresso espresso
The golden rule of an ideal espresso indicates the extraction time and the amount of extraction. The golden rule is a good guideline, but in many cases, color is a better indicator of grinding thickness and whether the packing is correct or not. Although it is not absolutely necessary, the extraction process can be clearly shown by observing the extraction with a bottomless cooking handle. When using the normal cooking handle, pass carefully
