The ideal time for coffee grinding is to grind it before cooking. Because ground coffee is easy to oxidize and lose its flavor, especially without proper storage, coffee powder is also easy to change flavor, so it is naturally impossible to cook mellow coffee.

Before the invention of the bean grinder, people used stone pestles and bowls to grind coffee beans. A doctor once experimented with this ancient tool and compared it with a modern bean grinder. It is said that the coffee powder made from pestles and stone bowls is the most mellow.

Coffee beans, the dark brown beans seem ordinary, but they have a lot of knowledge at all stages. For a coffee cook and drinker, it is enough to have a general understanding of the professional knowledge of the cultivation, production and roasting of coffee beans, and the production can be left to the coffee merchants. After all, this is an era of paying attention to the division of labor. However, it is the user's responsibility to grind and make coffee, and we must have a clear understanding.

When grinding beans, the size of the powder depends on the way it is cooked. The shorter the cooking time, the finer the ground powder; the longer the cooking time, the thicker the ground powder. In the way it is actually cooked, it takes a very short time for the ESPRESSO machine to make coffee.

Therefore, the coffee powder is the finest, and the coffee powder is as fine as flour; it takes more than a minute to cook coffee in the "plug wind" way, and the coffee powder belongs to medium-sized grinding; American filter coffee takes a long time to make, so the coffee powder is the thickest to grind, one by one like Beijing grains on a shell beach. Grinding coffee powder with appropriate thickness is very important to make a good cup of coffee, because the extraction of water-soluble substances in coffee powder has its ideal time, if the powder is very fine and cooked for a long time, resulting in over-extraction, the coffee may be very bitter and lose its aroma.

On the other hand, if the powder is coarse and cooked too fast, resulting in insufficient extraction, the coffee will be tasteless because it is too late to dissolve the water-soluble substance in the powder.

There are different brands and types of bean grinders for grinding coffee, and the ideal one is a grinder that can adjust the thickness of the beans. When grinding with a bean grinder, do not grind too much at one time, just enough powder for one time, because the longer the bean grinder is used at one time, the easier it is to get hot, which indirectly causes the coffee beans to be heated in the grinding process and causes the aroma to be released in advance, which will affect the aroma of the cooked coffee.

Coffee beans contain oil, so the bean grinder must be cleaned after grinding, otherwise the grease will be fouled and will smell stale after a long time, and even the most advanced beans will be ground into a strange-smelling powder. After each use of the bean grinder, be sure to wipe the blade table with the wet market and clean the plastic top cover with warm hot water.

But for the American popular flavored coffee, the added flavor is strong and strong, and it will last for a long time. It is best to put two tablespoons of white Jing sugar in and beat it before cleaning.

Of course, it is better for a grinder to grind only the same kind of beans, so there is no problem of mixing.

It's better to have a grinder to grind only the same kind of beans.

According to the size of coffee beans, the grinding methods can be divided into rough grinding, medium grinding and fine grinding. Use the appropriate grinding method according to the coffee utensils.

There is also medium fine grinding or very fine grinding (powdered coffee powder) which is finer than fine grinding.

The time to grind coffee beans is to grind only the required amount of coffee before brewing coffee. After the coffee bean is ground into powder, its surface area increases and absorbs moisture, which is easy to oxidize. In short, with the passage of time, coffee powder also plays a role of deterioration to damage the flavor.

And after the ground coffee beans are placed, the carbon dioxide retained inside the coffee beans will be lost together with the aroma.

In this way, when the coffee powder is extracted and filtered, the coffee powder should be expanded without expansion, and the coffee can not be brewed anyway. The secret is to consider grinding and homework consistently, so brewing coffee is the most delicious and mellow.

In the Middle East, people still use mashing to beat beans into particles of different sizes, but when most people are gradually using bean grinders, Bella-Shavalin personally did an experiment on whether it is better to mash or grind. For public trust, and food watchers were invited to taste the two kinds of coffee at the same time. In the end, everyone thought that the mashed coffee powder was more fascinating than ground coffee.

To grind satisfactory coffee powder, it is really very simple, as long as you try a few more times to find out your favorite flavor, in fact, there is no certain standard.

But generally speaking, the aroma of coffee powder (powerdered) that is too finely ground is easy to run away and is more suitable for fresh grinding and drinking.

Coffee powder that is too finely ground

The next level of coffee powder (veryfine) is used when using an electric coffee maker, because the fine coffee powder brews more coffee, which is often used by the general company or restaurant side drinks.

Then there is fine, which is about as thick as sugar, and dripping cooking is very suitable for this kind of thickness.

Medium (medium), the amount of granular coffee powder in brewing is small, you have to put more coffee particles, so the coffee brewed is more fragrant, some coffee pots also use medium coffee powder, because too fine powder will fall into the sieve plate, but the water in the pot takes more than 10 minutes to brew a pot of coffee and the amount is small, it can be said to be the most uneconomical particles.

There are many kinds of bean grinding machines, of which the most common is the household electric bean grinder, which can grind out particles of different sizes, small and light, and the price is not very expensive, so it is a good choice for families or people when there are few people.

The manual bean grinder is the kind that looks antique and picturesque in a coffee shop, even if it is not used as a decoration, but the particles produced by this bean grinder are relatively large and slow.

The professional electric bean grinder used in the coffee shop can grind out a variety of particles of different thickness. high speed and large quantity are the advantages of this kind of bean grinder.

Many new Espresso coffee machines are equipped with bean grinding function, but the risk is that it may not be able to meet your requirements, how to choose, it all depends on the choice of consumers.

When choosing, we should pay attention to the grinding knife in the machine, it is best to use a tapered coffee bean grinding knife, all tooth profiles are cut and shaped, to ensure that the tooth profile is sharp, uniform, accurate and stable grinding quality. Because the fine tooth of the tool is thicker than the coarse edge, the oblique edge makes the adjustment of the grinding thickness fast, and the powder can be fine or coarse and suitable for all kinds of coffee brewing requirements.

The powder can be fine or coarse, suitable for all kinds of coffee brewing requirements.

Espreeso uses pneumatic brewing, the whole process only takes 20-25 seconds, in such a short time, whether the essence of coffee can be properly extracted, the size of the powder is extremely important. If the powder is too fine, the area of steam penetration becomes relatively larger, which will cause excessive extraction, concentrated but not fragrant.

If the partner is too thick, the resistance is low, the coffee becomes thin, and the crema turns orange. Therefore, the purchase of bean grinder to have fine-tuning function is better. Cheap bean grinding mechanism image household multi-function mixer, the blade is in the shape of a windmill, and the ground beans are square in shape and unfavorable for extraction.

The use of coffee bean grinding knife head machine, sharp blade, wear and tear durable, so that coffee quickly crushed, so that coffee flavor is better, although the unit price is higher, but still worth it.

Blue Mountain Coffee (Blue Mountain Coffee)

It is a kind of coffee with high public awareness, which is produced only in the Blue Mountain region of Jamaica in Central America, and only coffee grown in the Blue Mountain area above 1800 meters can be authorized to use the logo of "Jamaican Blue Mountain Coffee," accounting for 15% of the total production of Jamaica Blue Mountain Coffee.

Kopi Luwak Kopi Luwak (Kopi Luwak)

Coffee is a recently invented coffee from Indonesia. Coffee beans are part of the civets' food range, but they cannot be completely digested by the digestive system.

Coffee beans are one of the civets' food range.

The coffee beans are fermented in the civets' intestines and stomach and excreted by the feces. The locals take out the coffee beans from the civets' feces and then do the processing.

That is, the so-called "cat shit" coffee, this coffee has a unique taste and different taste, but people who are used to this taste will never forget it for the rest of their lives. Due to the gradual deterioration of the wild environment, the number of civets is also slowly decreasing. As a result, the output of this kind of coffee is also quite limited, and people who can taste this coffee are very lucky.

CubitaCubita Coffee (amber coffee)

All produced in Crystal Mountain, Cuba, abbreviated as Cubita, Chinese name: Amber Coffee. It also has a high reputation in the coffee industry. Cuban Crystal Mountain Coffee ranks first in the world. Crystal Mountain is adjacent to the Blue Mountain Mountains of Jamaica, and its climatic conditions are similar to those of Jamaican Blue Mountain Coffee. Cubita adheres to the principle of perfect coffee, only making individual coffee, picking coffee beans by hand, plus washing coffee beans to ensure the quality of coffee.

The balance is excellent, the bitter taste and the sour taste are well matched, and there will be a delicate, smooth, fresh and elegant feeling in the taste. The designated coffee at the Cuban embassy is called the unique Caribbean flavor coffee.

Generally speaking, a good grinding method should include the following four basic principles

1. The degree of grinding suitable for cooking method should be selected.

2. The temperature of the cattle produced during grinding should be low.

3. The powder particles after grinding should be uniform.

4. Grind before cooking.

No matter what kind of grinder is used, it is bound to generate heat by friction in operation. Most of the fine substances are highly volatile, the heat of grinding will increase the speed of volatilization, and mellow is lost in the air.

After the coffee bean is ground, the cell wall will completely disintegrate, the area of contact with air will increase a lot, the rate of oxidation and deterioration will become faster, and the coffee will lose its flavor within 30 seconds to 2 minutes. Therefore, it is recommended not to buy coffee powder, it is best to buy coffee beans, grinding before drinking, grinding should be brewed as soon as possible. Before the invention of the bean grinder, people used stone pestles and bowls to grind coffee beans.

A doctor once experimented with this ancient tool and compared it with a modern bean grinder. It is said that the coffee powder made from pestles and stone bowls is the most mellow.

According to logical reasoning, the pestle cracked the coffee bean naturally by impact, which should not destroy the cell wall and retain the excellent substance of coffee.

However, in modern life, it is almost impossible for people to use pestles and stone bowls to grind coffee beans, so it is particularly important to choose a good bean grinder.
