Fine coffee technology fine coffee bean grinding skills

The grinding of roasted coffee beans into powder is called grinding, and the props for grinding coffee beans are called grinding. Beethoven put sixty coffee beans into the mill every morning, grind them and brew coffee. Grind your coffee and enjoy its aroma. Then enjoy it with gusto.

Coffee beans grinding methods can be slightly divided into coarse grinding, medium grinding and fine grinding according to their size. Use appropriate grinding methods depending on coffee equipment. There is also a medium fine grind or a very fine grind finer than fine grind (into powdered coffee powder). And coffee beans grinding time is brewing coffee before, only the need for grinding is the top grade. Coffee beans are ground into powder and their surface area increases to absorb moisture and oxidize easily. In short, with the passage of time, coffee powder also plays a role in the deterioration of flavor damage. Also, after the ground coffee beans are placed, the carbon dioxide and aroma retained in the beans will be lost together. In this way, the coffee powder should expand and not expand when extracted and filtered, and no matter how it is, it cannot make delicious coffee. And the secret is to consider grinding consistently with the job, so that brewed coffee is the most delicious and mellow. Finegrind ◎ Fine grind (fine particles, the same size as granulated sugar) Mediumgrind ◎ Medium grind (particles the same size as granulated sugar mixed with coarse white sugar) Regulargrind ◎ Coarse grind (coarse particles, the same size as coarse white sugar) The key to grinding coffee beans Coffee powder Coffee beans grinding tools are grinders.

Grinders range from manual for home use to large electric for business use. Household grinders can also be used as decorations, and if the number of people wants to grind once, it is still convenient to use electric grinders. According to the structure of the grinder, there are grinders that use vertical and horizontal grooves to cut coffee beans and grinders that grind coffee with molars. Each has its own strengths, and the situation of business use is the trend of mass production of electric type as the mainstream.

However, grinding coffee beans should pay attention to the following two points: ① friction heat suppression to a minimum limit. (Aromatic components will scatter due to heat) ② Uniform size of particles. (The particles are not uniform, and the concentration of the brewing will be uneven) For this consideration, if it is a household grinder, manually rotate it gently, and pay attention to making it as free as possible. Therefore, it is more appropriate to use electric grinders.

Grind beans before brewing. There are two types of household grinders: manual and electric. A small number of words with manual, and a large number of words with electric more convenient. The grinding method (particle size) is determined by the use of a suction device. Manual grinders should be careful not to generate frictional heat only. And be careful if you mix anything else. After grinding coffee beans particles large neat or not, to check. (If the particles are uneven, it is possible that the function of the grinder is always the same, or the coffee roasting is uneven.)

Coffee grinds In the Middle East, beans are still ground into particles of varying sizes, but when most people have gradually used bean grinders, Bella Sawarin personally conducted an experiment to determine whether ground or ground coffee is better, both for public trust, and invited food critics to taste the two kinds of coffee. Finally, it was agreed that ground coffee is more fascinating than ground coffee. To grind a satisfactory coffee powder, it is really very simple, as long as you try a few times to find your favorite flavor, in fact, there is no certain standard. But generally speaking, too fine ground coffee powder (powerdered) aroma is easy to run away, more suitable for fresh ground drink. To the next level of coffee powder (very fine) is used when using electric coffee pot, this is because the coffee made of fine coffee powder is more, general company line number, or restaurant with a meal drink more with this kind. Then there is fine, which is about the size of granulated sugar, and the dripping cooking method is very suitable for this kind of thickness. Medium (medium), granular coffee powder in the brewing amount is not much, have to put more coffee particles to do, so the coffee brewed is more fragrant, some coffee pots also need to use medium coffee powder, because too fine powder will fall into the sieve plate, but the pot of water needs more than 10 minutes to cook a pot of coffee and the amount is not much, can be said to be the most economical particles. There are many kinds of machines for grinding beans, among which the most common is the electric bean grinder for family use, which can grind particles of different sizes, small and light, and the price is not very expensive. It is a good choice for families or when there are few people. Manual bean grinder is the kind of coffee shop, looks ancient, very poetic that kind of, even if not used as a decoration to grind beans is also very beautiful, but this one grinds out the particles are relatively large, and the speed is also relatively slow.

Coffee shop with professional electric grinder can grind out a variety of different thickness of particles, speed, weight is the advantage of this grinder. Many new Espresso coffee machines are equipped with the function of grinding beans, but the risk is that it may not be able to meet your requirements, how to choose, all depends on the consumer's choice. Espreeso uses air pressure brewing, the whole process only takes 20-25 seconds, in such a short time, coffee essence can be properly extracted, powder particle thickness is very important. If the powder is too fine, the area of vapor penetration will be relatively large, which will cause excessive extraction, thick and not fragrant. Coarse grains, low resistance, coffee becomes thin, creme orange. Therefore, it is better to purchase a bean grinder with a fine-tuning function. Cheap bean grinders are constructed like household multifunctional mixers, with windmill-like blades, square beans after grinding, which is not conducive to extraction. Using circular saw blade machines, beans will be irregular, wide contact surface, although the unit price is higher, but still worth it.
