qianjiez2, coffee grinder, coffee should be enough for everyone to pay attention to 0, 1zzzzz1 One of the most money-burning players ! ! !

Making coffee itself has many influencing factors, ranging from light to heavy, such as coffee powder, proportion and water temperature. The quality of the grinder is very important to a cup of coffee.

gives an example of the powder produced by a poor-quality bean grinder. The thickness of the powder is uneven. There are large and small particles. When a stream of hot water is washed down, the large particles have not been extracted within three minutes, but the particles are small. The coffee powder in the container is not evenly distributed. The side with more coarse powder will be over-extracted at high water temperature; the side with more fine powder will be incompletely extracted at low water temperature. This concept is the same for all methods of making coffee, no matter what thickness of coffee needs to be ground. Excessive extraction will make the coffee become tingling and bitter, incomplete extraction will make the coffee very little flavor, only sour...

How should you set a budget for your grinder?

I can tell you a very simple and fast rule, that is, when buying a grinder that is less than $200, your coffee machine and grinder should each account for half of your budget, and when your budget When it's bigger, your grinder's share of the entire budget can decrease.

In other words, if your budget is US$500, you will spend about US$200 to US$250 for the grinder and US$250 to US$300 for the coffee machine. And if your budget is $1,000, you can consider spending $300 to $350 to buy a grinder, and $650 to $700 to buy a coffee machine.

I know that some readers will definitely question and may laugh at me for spending $300, or even more, for just enough to buy a mill. But if you spend $1,000 on a machine, the $300 mill will actually not account for much of the overall budget. One reality you have to accept now is that the grinder is crucial in the entire coffee equipment purchase process. Let's think about it in this way, coffee equipment purchase budget = coffee machine + grinder + additional equipment, rather than coffee equipment budget = coffee machine. Practice can fully prove this point. When you have a good grinder, your espresso will even make 95% of the professional cafes beyond reach, and it is easier to make.

Coffee money burning grinders

grinders can generally be divided into three categories: flat knives, cone knives and ghost teeth.

Flat Knife: The coffee beans are ground into granules by cutting, so the shape is mainly flake.

Cone Knife: The coffee beans are ground into particles by grinding, so the shape is mainly block.

ghost tooth: The coffee beans are ground into particles by grinding, so their shape is mainly close to circular.

Little Fuji Ghost Teeth

​​A few years ago, which coffee shop had Taiwan Little Fuji, that is something to be proud of. But in the whole domestic coffee industry, the equipment does not require (sex) the most (price) better (ratio) , but the most expensive. Little Fuji is regarded as an arcade machine in this era. The Fujiroyal Fujiroyal electric grinder R-220 ghost tooth 220V imported from Japan , the saw tooth is also called ghost tooth, ghost tooth grinder is generally not suitable for grinding very fine powder, ghost tooth is suitable for Grinding of drip coffee.

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

Mazzer Mini espresso quantitative coffee grinder

belongs to commercial professional espresso grinder , is a professional grinder, I recommend a more suitable for small cafes , the price It is about 4800 yuan+. It is mainly used for Italian quantitative coffee grinding to control the amount of coffee beans each time. Moreover, the size of the grinder is relatively small. This one is also suitable for enthusiast coffeeUsed by coffee lovers.

Mazzer's uniquely developed stepless adjustment cutter head allows coffee lovers to adjust the thickness of the grinding as they wish, precisely to match the characteristics of the beans and the needs of coffee lovers. Its brewing handle rack is convenient for fixing the handle and Make the ground powder fall into the filter cup, and the grinding outlet with dispersing net can effectively improve the generation of powder lumps. All in all, this is a conscientious company, and it is worth studying carefully~

BG

​​This grinder can only produce single-origin coffee (not for Italian grinding), the market price is 5500, and the design of the bean store is different. It is not very convenient for coffee beans, and everything is fine without considering the waste of grinding time and the need for a small brush to help the beans at the edge of the bean bin jump off each time the beans are inserted. The looks very beautiful visually, because it is light and handy. If you are a small independent cafe, I believe that the thinking about the so-called production line is also constantly adjusted. Buying one can set the time and weight, with LCD Touch screen (it sounds very tall), coffee friends can pre-set the grinding time of each button, the minimum interval can be set to 0.05 seconds, or you can use the manual button to determine the grinding time and powder amount. And it is a single-product mill that a girl can take away, which is really good.

Mahlkonig EK43

Someone used EK43 to make Italian coffee in the WBC barista competition in a certain year. This gave everyone a peculiar and forced enjoyment. Ever since, a new round of burn-in campaign began. . . Suddenly, I found that the coffee friends around were all talking about this grinder, and then it was crazy to pursue and buy it. And after the manufacturers tasted the sweetness, they began to be shameless. Sponsor the game, stipulate that some games can only use their machine blabla. This is a well-deserved new generation of machine god, his frequency of appearance has reached the point of arcade, these years, there is no EK43 town store, I am embarrassed to tell others that you sell a single product,

this is EK43 ground coffee powder : The data shows that the EK43 ground particles are not only the smallest, but the texture is the most uniform, which means that the extraction of coffee is more uniform, the degree of extraction tends to be perfect, and there will be no excessive extraction.

Mehdi Mahlkonig-Ek43/EKK43 uses a 98mm steel alloy flat cutter head, and the coffee using Ek43/EKK43 shows a significantly better body (body fat), thick and soft, and it is very comfortable to wrap on the tongue. , EKK43 abrasive particles are mostly spheres and cubes, the cross-section is more common, and the particle consistency is better. The material and design of the Ditting KR804

grinding cutter head has always been the core of the Ditting grinder. When the grinder is driven by a high-torque motor, it must be able to withstand the heavy load generated during the grinding process. After the coffee beans go through the grinding step, the thickness of the coffee powder is kept consistent. More importantly, ensure that the coffee beans will not affect the roasted flavor due to overheating during the grinding process. Half a century later, the Swiss precision grinder produced by Ditting has grown with the ever-changing needs of this industry, and it has also set a standard for the grinder industry. The ditting kr804, the artifact in the

coffee mill, originated from Switzerland. It first started to produce auto parts and then gradually transformed to develop the material for the coffee grinder. This kr804 comes from ditting and is considered one of the masterpieces. , The photogenic rate is very high.

Compak R120

comes from Compak in Spain. It is definitely an unpopular brand with low visibility. But with this freak, the R120, was born in the world of grinders. R120 is definitely the Titan in the grinder. With a huge cutter head, unusual figure, and an unprecedented weight of 38 kg (net weight). And many designs are also very special in commercial single-product grinders, such as the thickened all-metal aluminum alloy shell, the internal use of chain drive adjustment, and the servo motor assisted powder output. In a series of peculiarUnder the combination, the price is also shocking. In terms of taste,

uses EK43 and R120 to grind and extract espresso. Everyone agrees that the taste of R120 espresso has more gradation changes, the sweetness is also higher, and the extracted substances are more. This must be the credit of the finer powder. Whether it is good or bad depends on the user, because it needs to be used with the beans and with the rough and young. Because in the same way, the bad substances will also run out because of the high extraction rate, so it depends on the cooperation of the barista.

uses EK43 and R120 in the cupping part for comparison. In the dry fragrance part, everyone feels the same. The dry fragrance of EK43 is better, and R120 is more subtle. When it comes to cupping, we use the same thickness The degree of coffee powder is mainly in the size of 24 mesh (0.8mm) powder, the same amount of powder, the same water temperature, and the same time, we found that the taste of R120 changes more than EK, and the sweet and sour feeling is stronger. EK is more stable, sweet in taste but less variable. This is everyone's conclusion.

Mahlkonig Guatemala

comes from Guatemala, the home of the devil, and originated from the Stawert Mühlenbau manufacturing company. The traditional family business was founded in Hamburg, Germany in 1924 AD. 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 line is the production of professional coffee grinders. GUATEMALA Lab (Guatemala) uses a 65mm cutter head, and the price is not cheap. Guatemala's ground particles have sharp edges.

Eureka MCD4

Eureka comes from Italy and was born in 1920. It was a manufacturer of electric milkshake machines before World War II. After the war, it began to switch to other food and beverage equipment, and coffee grinders were one of them. At present, Eureka has concentrated on making coffee grinders. The product line of Eureka is relatively rich, and there are no shortage of good machines, but it is a niche brand in China, mainly because there are not many people who choose, and the visibility is low. Simple design, metal body, quick powder output, wide grinding scale, disadvantages: The biggest disadvantage is that the residual powder rate is too high. Recommended for

household magic bean machine:

Taiwan Zhenghuangxing 300-400 flat knives

cone knife grinding disc

Advantages and disadvantages:

cone knife grinder is placed on the bottom of the cone cutter, and then matched with the outer ring cutter disc for grinding. After the coffee beans fall from above, they will pull the coffee beans downward with the rotation of the cone cutter, and then produce the grinding action. Also because of the relationship from top to bottom, the particles can push the coffee out without pushing Compared with a flat knife grinder, the number of collisions between particles will be much reduced, so the proportion of fine powder produced by the cone knife will be much less than that of the flat knife, and the coffee grinding 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 longer to reach the water inside. Therefore, the cone knife particles will release less soluble substances in the initial stage, resulting in a short concentration The internal content will not be too high. At the same time, because the shape is granular, even if it is extracted for a long time, the xylem absorbs less water and is less likely to produce offensive and astringent flavors.

When you need to getThe flat knife grinder is a good choice when you have a higher concentration of coffee. The high concentration will also make the aroma strong, so the aroma will be much more pronounced when using a flat knife than a cone knife; when a better taste is required, the cone knife produces The granular coffee powder can reduce the xylem contact time. Although the aroma is not as obvious as a flat knife, even if the extraction time is extended, the taste is still better.

recommended for household magic bean machine:

Taiwan’s little Pegasus ghost tooth 500-600

domestically produced small Fuji

commonly known as "small steel gun": 600-700 yuan

There is also a domestic propeller-type grinder The kind of bean grinder that drives two blades (between 100 and 200), it is actually not a bean grinder, but a "bean chopper". One of the disadvantages is that the thickness of the cut coffee powder is different; the second is that high heat is generated during the chopping process, which destroys the valuable oil and aroma in the coffee beans; the third is that the thickness of the coffee powder cannot be adjusted.

The first principle of successful extraction of specialty coffee (uniform extraction), because the coffee powder particles cut by the bean chopper are coarse and fine, it will also cause the coffee extraction to fail! The most direct is over-extraction or under-extraction! Under-extracted coffee will be sour and puffy, and over-extracted coffee will be too bitter! Grinding comparison of

:

is adjusted to the same scale, such as scale 4, grinding the same beans, and then observing the uniformity and powder thickness with the naked eye is a common way, but the cutter head design is different, and the powder state performance under the same scale may not be consistent. The grinding effect of

is swaying the flat knife grinder

Xiaofeiying ghost tooth grinder The grinding effect of

Then let's look at the effect of the powder structure on the extraction? The particles will be closer to the oblate rectangle, while the block shape produced by the cone knife is close to the hexagonal shape. The powder grain produced by the ghost tooth has a long and slender waist and is smoother. The powder and powder will couple better. The powder particles ground by the

• knife are less than the convex fulcrums of the cone knife, the particles are in block, and the waist is thicker than the ghost teeth. thinks that the water resistance of the flat knife powder should be the largest!

• Cone-knife powder particles under the microscope, the main structure of the powder particles will have many raised outer fulcrums, just like a hedgehog. After many powder particles are gathered, it is impossible to completely couple the powder particles because of the external pivot. The gap will be larger, and the speed of the water flow will be faster. The water flow is faster, so the extraction is relatively low.

• The powder particles of ghost teeth, the powder particles grinded by ghost teeth have a long and slender waist, which is relatively smooth, and the coupling between powder and powder will be better. The gap is also small, and the water flow will be relatively slow when passing through, and relatively more extracted. The waist of ghost tooth powder is too thin, and the resistance must be small compared with peace knife powder. So the powder produced by the flat knife, from the structural point of view, the powder has less convex fulcrums, so the coupling is much better than that of the cone knife powder. The gap is tighter than the cone knife, the water resistance is larger, and the extraction is more.

  
  

From the perspective of taste, the same beans, the same amount of powder, the same water temperature, the same fineness of powder, flavor comparison:

• flat knife flavor is more bold, single

• zzzzzknife is more rounded, complex, and has a clean flavor of

In recent years, as the concept of specialty coffee has become popular, single-product hand-punching has also followed this craze, and even Xingbaba has begun to wander in the muddy water. With the popularity of single-origin hand brewed coffee, related brewing equipment is also continuously updated and iterated, one after another. The price is also rising all the way. In the early years of , as one of the most economical brewing methods for hand-brewed coffee, you may be able to make a good effort for a few thousand RMB. Now this number may be tens of thousands. .. And the main thing that accounts for the bulk is the price of the grinder. This also reflects from the side that the coffee industry is paying more and more attention to the grinder.

Hand Grind [Brand Introduction]

Many people are using Zhenghuangxing A12 economical, Kyocera, HARIO and TIAMO are also good, HARIO copy Kyocera, TIAMO copy HARIO. The grinding core of HARIO is made by Kyocera and assembled in China. The grinding core of Kyocera CM45 can grind the powder needed by espresso. I personally feel that the powder for grinding espresso is better than a special electric grinding machine (except for the best hand grinding, such as HG-ONE).

Handground

The process of hand-grinding coffee beans is always intermittent. The emergence of Handground Precision Coffee Grinder is to change all of this. It uses ceramic serrations and camera-like ring design, so that the grinding thickness becomes 125 micrograms each time. At the same time, the triple stainless steel shaft design makes it work. Can be more continuous. This grinder with so many functions is only $65.
