Bean grinder selection guide| Burning money! Bean grinder is more important than Italian machine, how to choose bean grinder

Coffee grinder should attract enough attention, and it is also one of the most expensive coffee players!

Making coffee itself can be affected by many factors, such as coffee powder, proportion and water temperature. The quality of the bean grinder is important for a cup of coffee.

For example, the powder ground by a poor quality bean grinder is uneven in thickness, large and small, and when a stream of hot water rushes down, within three minutes, the large particles have not been extracted, and the small particles are excessively extracted; the coffee powder in the container is unevenly distributed, and the side with more coarse powder will be extracted too much at high water temperature; the side with more fine powder will be extracted incompletely at low water temperature. This concept is the same as all methods of making coffee, no matter how much coffee needs to be ground. Excessive extraction will make the coffee numb and astringent on the tip of the tongue, and incomplete extraction will make the coffee have very little flavor and only acid.

How should you set the budget for your bean grinder?

I can tell you a very simple and quick rule, that is, when buying a $200 bean grinder, your coffee machine and bean grinder should each account for half of your budget, and when your budget is bigger, your bean grinder's share of the entire budget can be reduced.

In other words, if your budget is $500, you will spend about $200 to $250 on a bean grinder and $250 to $300 on a coffee maker. If your budget is $1000, you can consider spending $300 to $350 on a bean grinder and $650 to $700 on a coffee maker.

I know that some readers will certainly question it, and may laugh at me for spending $300 or more to buy a mill. But if you spend $1000 on a machine, the $300 mill doesn't really make up much of the overall budget. Now you have to accept the fact that the bean grinder is very important in the whole process of purchasing coffee equipment. Let's think about it this way, coffee equipment purchase budget = coffee machine + bean grinder + additional equipment, rather than coffee equipment budget = coffee machine. Practice can fully prove this, when you have a good bean grinder, your espresso will even be unmatched by 95% of professional cafes, and it will be easier to make.

A bean grinder for burning coffee

Bean grinders can be divided into three categories: flat knife, conical knife and ghost teeth.

Flat knife: coffee beans are ground into particles by cutting, so its shape is mainly flaky.

Cone knife: the coffee bean is ground into particles by grinding, so its shape is mainly block.

Ghost teeth: coffee beans are ground into particles in the way of grinding, so their shape is mainly close to circle.

Little Fuji ghost teeth

A few years ago, which coffee shop had a small Fuji inside, it was a thing worth bragging about. However, in the entire domestic coffee industry, the equipment is not the best (price), but the most expensive. Small Fuji in this era is an arcade, Fujiroyal Fuji electric grinder R-220 ghost teeth 220V imported from Japan, serrated teeth are also known as ghost teeth, ghost teeth grinding is generally not suitable for grinding very fine powder, ghost teeth are suitable for drip coffee grinding.

The first choice for professional entry, the particles are quite uniform ~

Mazzer Mini quantitative Coffee Grinding

Is a commercial professional Italian bean grinder, is a professional bean grinder, recommend a more suitable for small coffee shop, the price is about 4800 yuan +, mainly used for Italian quantitative coffee grinding, control the amount of coffee beans each time, and the relatively small size of the bean grinder, this one also meets the use of feverish coffee lovers.

Mazzer exclusive research and development of the stepless adjustment cutter head, so that friends can adjust the thickness of grinding, accurately match the characteristics of beans and the needs of friends, its cooking handle rack, easy to fix the handle and make the grinding powder really fall into the filter cup, and contains the grinding outlet of the dispersion net, which can effectively improve the production of the powder. All in all, this is a company with a conscience, which is worth studying.

BG

This bean grinder can only produce single coffee (not for Italian grinding). The market price is 5500. The design of the bean warehouse is not convenient to switch between different coffee beans. Without considering the waste of grinding time and the need for a small brush to help the beans jump off the edge of the warehouse, everything is fine. It looks very beautiful visually, because it is light, if you are a small independent cafe, I believe the thinking about the so-called production line is also constantly adjusting, buying one can set the time and weight. With LCD touch screen (which sounds very tall and high), friends can set the grinding time of each button in advance, and the minimum spacing can be set to 0.05 seconds. You can also use manual keys to determine the grinding time and powder quantity. And it is a single mill that can be carried away by a girl, which is really a good thing.

Mahlkonig EK43

After someone used EK43 to make espresso in the WBC barista competition one year, it gave everyone a strange enjoyment. As a result, a new round of machine burning movement began. All of a sudden, I found that the coffee friends around me began to talk about this bean grinder, and then went crazy to pursue and buy it. And the manufacturers began to be shameless after tasting the sweetness. Sponsor competitions, stipulating that some competitions can only use their machine blabla. This is a well-deserved new generation of machine god, his frequency has reached the level of arcade, these days, there is not an EK43 town shop, are embarrassed to tell others that you sell single products

This is the coffee powder ground by EK43: the data show that the EK43 grinding particles are not only the smallest, but also the most uniform, which means that the extraction of coffee is more uniform, the degree of extraction tends to be perfect, and there is no over-extraction.

Mehdi Mahlkonig-Ek43/EKK43 uses 98mm steel alloy flat cutter head, using Ek43/EKK43 coffee shows significantly better Body (body fat feeling), thick and soft, the wrapping feeling on the tongue surface is very comfortable, EKK43 grinding particles are mostly spheres and cubes, cross-section circles are more common, particle consistency is better.

Ditting KR804

The material and design of the grinding cutter head has always been the core of the Ditting bean grinder. When the grinding machine is driven by a high torque motor, it must be able to resist the heavy load produced during grinding, and the advantages of the grinding cutter head design can make the coffee beans consistent in thickness and fineness after the grinding steps. More importantly, during the grinding process, make sure that coffee beans do not overheat and affect the flavor of roasting. Half a century later, the Swiss precision bean grinder produced by Ditting grew with the changing needs of the industry and set a set of standards for the bean mill industry.

Ditting kr804,ditting, the artifact in the coffee mill, originated from Switzerland, started to produce auto spare parts, and then gradually transformed, devoting itself to the research and development of the grinding plate material of the coffee grinder. This kr804 comes from ditting and is one of the masterpieces with a high photogenic rate.

Compak R120

Compak from Spain is definitely an unpopular brand, and its visibility is also very low at ordinary times. However, with this R120 freak, he was born in the bean grinder world. The R120 was definitely the Titan in the bean grinder. It had a huge cutterhead, an unusual figure, and an unprecedented weight of 38 kilograms (net weight). Moreover, many designs are also very special in commercial single product grinding machines, such as: all-metal aluminum alloy shell thickening, internal chain transmission adjustment, servo motor auxiliary powder, etc. In a strange combination, the price is also shocking.

In terms of taste, using EK43 and R120 grinding, extracting espresso, we all agree that R120 espresso taste has a higher level of change, sweetness is also higher, extract more substances, this must be more fine powder credit. This is good or bad depends on the user, because to cooperate with beans and with coarse and young use, because similarly, bad substances will also run out because of the high extraction rate, so it depends on the cooperation of the barista.

In the cupping section, use EK43 and R 120 for comparison. All felt the same about the aroma, EK43 had better aroma and R 120 was more subtle. And to the time of cupping, we use the same coarse and fine coffee powder mainly in 24 mesh (0.8mm) powder size, the same powder, the same water temperature, the same time, we found that R120 taste more changes than EK, sweet and sour feeling stronger, while EK is more stable, sweet taste but less change, this is all people come to the same conclusion.

Mahlkonig Guatemala

Guatemala, from the family of the Devil King, originated from the Stawert M ü hlenbau Manufacturing Company. The traditional family business was founded in 1924 in Hamburg, Germany. The first is the production of industrial electric motors. Soon, the company was widely involved in other mechanical grinders, such as coffee, corn, and spices. Since 1960, the company has been focusing on the production of coffee grinders, and now more than 90% of MAHLK?NIG 's product lines are professional coffee grinders. GUATEMALA Lab (Guatemala) is the use of 65mm cutterhead, the price is not cheap, Guatemala grinding particles with sharp edges.

EurekaMCD4

Eureka, from Italy, was born in 1920. Before World War II, it was a manufacturer of electric milk machines. After the war, it began to switch to other food and beverage equipment, and the coffee grinder is one of them. At present, Eureka is already focused on making a coffee grinder. Eureka's product line is relatively rich, and there is no lack of good machines, but it is a minority brand in China, mainly because there are not many people to choose and low visibility. Simple design, metal fuselage, rapid powder production, wide grinding scale, disadvantage: the biggest disadvantage is that the residual powder rate is too high.

Taiwan is sloshing 300-400 flat knives

Cone knife grinder

Advantages and disadvantages:

Cone knife grinder is placed at the bottom of the conical cutter disc, and then with the outer ring cutter disc to grind, coffee beans fall from above, coffee beans will be pulled down with the rotation of the conical cutter disc, and then produce grinding action, but also because of the relationship from top to bottom, so the particles can be pushed out without pushing coffee, compared with the flat knife grinder, the number of collisions between particles will be reduced a lot, so the proportion of fine powder produced by the cone knife will be reduced a lot compared with the flat knife, And the coffee grind uniformity will be greatly improved.

The particles ground by the cone knife will be close to the granular shape, resulting in a longer water absorption path of the coffee particles, and it takes a longer time to contact the water inside. Therefore, the soluble substances released by the cone knife particles in the early stage will be less, resulting in a concentration that is not too high in a short time. At the same time, because of the granular shape, even if extracted for a long time, the xylem absorbs less water, and it is less likely to produce miscellaneous taste and astringency.

Ghost tooth grinding plate

Advantages and disadvantages:

The coffee powder particles of ghost tooth grinding are close to round, and the proportion of coarse powder and fine powder is more uniform, so the coffee taste is cleaner, the flavor is more three-dimensional and full, but the machine price is higher.

When you need to get a high concentration of coffee in a short time, the flat knife grinder is a good choice, and the high concentration will also make the aroma rich, so the aroma of the flat knife will be much more obvious than that of the cone knife; when a better taste is needed, the granular coffee powder produced by the cone knife can reduce the time for xylem to come into contact with moisture, although the aroma is not as obvious as the flat knife, but even if the extraction time is prolonged, the taste is still better.

Taiwan Pegasus 500-600

Domestic little Fuji

Commonly known as "small steel cannon": between 600 and 700 yuan

There is also a household propeller bean grinder (that is, a bean grinder with two blades driven by an electric motor, 100-200), which is actually not a bean grinder, but a "bean chopper". Its disadvantage is that the coffee powder cut out is of different thickness; second, the process of chopping beans produces high heat, which destroys the precious oil and aroma of coffee beans; third, it can not adjust the thickness of coffee powder.

Under the first principle of successful extraction of fine coffee (uniform extraction), because the coffee powder particles chopped by the chopping machine are coarse and fine, it will also lead to the failure of coffee extraction! The most direct is excessive extraction, or insufficient extraction! The coffee with insufficient extraction will be sour and astringent, and the coffee with excessive extraction will be too bitter!

Grinding comparison:

It is a common way to adjust to the same scale, such as scale 4, grind the same beans, and then observe the uniformity and powder thickness with the naked eye, but the cutter head design is different, the powder state under the same scale may not be the same.

So what is the effect of powder structure on extraction?

Flat knife grinding flake particles will be closer to the oblate rectangle, while cone knife grinding block is close to hexagonal, ghost tooth grinding powder waist slender, relatively smooth, the coupling between powder and powder will be better.

The powder grinded by the knife is less than the raised fulcrum of the cone knife, the particles are lumpy, and the waist is stronger than the ghost teeth. A person thinks that the water resistance of flat knife powder should be the greatest!

Cone knife powder under the microscope, the main body of the powder structure will have many protruding outer fulcrum, just like a hedgehog. After many powder particles gather, it is impossible for the powder particles to match completely because of the external fulcrum. The gap will be larger and the flow of water will pass faster. The flow of water passes faster, so the extraction is relatively low.

Ghost tooth powder, ghost tooth grinding out of the powder waist slender, relatively smooth, the coupling between powder and powder will be better. The gap is also small, the flow of water through will be relatively slow, and the extraction will be relatively more. Ghost tooth powder waist is too thin, peace knife powder compared to the resistance must be less. Then the powder ground by the flat knife, from the structural point of view, the convex fulcrum of the powder particles is less, so the coupling is much better than the cone knife powder. The gap is tighter than the cone knife, the water resistance is also larger, and the extraction is also a little more.

In terms of taste, the same beans, the same amount of powder, the same water temperature, the same fineness of powder, flavor comparison:

The flavor of flat Dao is unrestrained and unitary.

The flavor of conical knife is more round and complex.

The flavor of ghost teeth is clean, and the flavor is three-dimensional and full.

In recent years, with the popularity of the concept of boutique coffee, single product hand brewing is also with this craze, wind unboiled water rises, even star poop has begun to get involved in this muddy water. With the popularity of single-product hand-brewed coffee, the related brewing equipment is also constantly updated and iterated one after another. The price is also going up all the way. In the early years, as one of the most economical methods of brewing coffee, you might have spent a few thousand RMB to make a good match. Now the number may be tens of thousands. And the main part of this is the price of the bean grinder. This also reflects from the side that the coffee industry pays more and more attention to the bean grinder.

Hand mill [brand introduction]

Many people are using the sloshing A12 affordable, Kyocera, HARIO and TIAMO are also good, HARIO shanzhai Kyocera, TIAMO copycat HARIO. The grinding core of HARIO is manufactured by Kyocera and assembled in China. The grinding core of Kyocera CM45 can grind the powder needed by espresso. I feel that grinding espresso powder is better than special electric grinding (not the best hand mill, such as HG-ONE).

Handground

The process of grinding coffee beans by hand is always intermittent. The emergence of Handground Precision Coffee Grinder is to change all this, it uses ceramic sawtooth and camera-like ring design, so that the thickness of grinding to 125 micrograms per time, at the same time, the triple stainless steel shaft design allows it to operate more continuously. This bean grinder with so many functions costs only $65.

Hario MSS-1B hand bean grinder, the price is about 200. ceramic core grinding, entry-level hand mill

[TIAMO] Taiwan brands are almost all made in mainland China, and TIAMO's plastic is just like that.

[Japanese Kalita classic hand coffee grinder]: it's hard to grind, and it's highly ornamental.

[Kyocera Kyocera CM-45CF]: it's hard to grind, and it's very convenient to clean.

[positive AKIRA A Mel 13]: cast iron grinding core, fine grinding point is good, calculate uniform, rough grinding is not uniform.

[Japan PROLEX]: recently, it is quite popular, grinding fine powder is better, ceramic core grinding.

[OE Lido 2] the price is also very high, but the important thing is that the flour quality is good. As a hand mill, it is the best choice for hand flushing to adjust to a relatively large size to test that the uniformity of the product particles is uniform and multilateral particles.

[Super Italian Hand Grinder HG-One] This hand grinder developed by American enthusiasts is equipped with an 85mm tapered cutter head and uses precise infinite fine adjustment scales to grind any fineness. The idea of the producer is that it can be used at home, green and environmentally friendly beyond the hand mill of the electric bean grinder, because it is vertical powder, so there is only a small amount of residual powder. But it's expensive ($915).

[Zassenhaus Panama stainless steel hand bean grinder]: it adopts two-axis fixed, steel conical grinding head, which is an European classic hand bean grinder brand, with fixed middle shaft and uniform grinding.
