Grinding the coffee too coarse will make the coffee weak. Grinding too fine will make the coffee murky and taste bitter.
WHERE IS ENOUGH?
Coffee after grinding can only keep the aroma for a few days. So, if you are a sophisticated and strict person in drinking coffee, the best way is to grind your own coffee right before drinking to have a fresh and delicious cup of coffee.

Before grinding coffee, you must know how you will make coffee, with what tools, because each type of coffee maker will need coarse, medium or very fine ground coffee to be suitable. with different brewing methods. The faster the coffee is cooked in hot water during the coffee making process, the finer the coffee beans need to be ground to release the full aroma.
Different levels of coarseness of coffee will suit different brewing methods.
1. What factors affect the quality of espresso coffee?
The first factor is the size of the espresso powder. The larger the espresso beans, the faster the water flows through the coffee. As a result, the short extraction time results in a more sour and diluted espresso. Meanwhile, if the coffee bean size is too small, the ground coffee will be too fine, the hot water will be in contact with the coffee more and longer. Therefore, the coffee taste will be more bitter and have a burnt taste.
According to experts, espresso beans must be ground to a fine level. To get this you need to buy a coffee grinder with a gear-shaped blade instead of a single blade. Because this type of knife can adjust the fineness of the coffee powder by customizing the distance between the 2 knife plates for a more uniform, finer quality of coffee powder.
The second factor is the uniformity of coffee beans. Good coffee grinders will give smooth and highly uniform coffee powder. The size of the powder molecules is even to help distribute the water evenly. To get the coffee powder with high homogeneity. Then the key point you need to note is in the two parts of the grinder and the motor. The grinder part of the coffee grinder must be cast from industrial steel or titanium alloy that is hard and wear-resistant. Under a fast rotation speed of over 1000 rpm, the distance between the 2 blades is perfectly balanced. Thereby helping you grind the coffee to meet the standards.
The third factor is the temperature when grinding espresso. Accordingly, the aroma of coffee beans will be affected by temperature, light and oxidation. While grinding the coffee beans will come into contact with the blade. If the friction force is large, heat will be generated. If this temperature is too high, the original coffee flavor will be lost. This leaves your espresso with a burnt smell. To limit this, you need to use a coffee grinder with a grinder made from super-hard titanium alloy and the diameter of the coffee grinder must be larger than 50mm to help cut beans faster and reduce friction time.
2. Experience in choosing the right espresso machine for the cafe
To buy the right espresso machine for your coffee shop, you need to pay attention to some of the following issues:
2.1. How much does it cost to buy a coffee grinder?
You need to determine if the machines are in the price range you can afford. There are many types of espresso machines on the market today. In particular, the models imported from Europe are very popular. Normally, this machine will be paid about 20 million to 30 million for a traditional sized commercial coffee grinder.

2.2. Select by type of coffee grinder
On the market today, there are two popular lines of coffee grinders: manual quantitative coffee grinders and automatic quantitative coffee grinders. Accordingly:
Manual quantitative coffee grinder is a semi-automatic coffee grinder without a dosing unit. This type of coffee grinder will have a powder compartment in the front. When the On button is turned on, the coffee beans will be ground continuously and stored in the front powder container. The ground coffee, after being ground, will fall directly into the waiting coffee container. This line is also divided into 2 branches: Manual Dosing (pure mechanical) and Auto Dosing (automatic grinding and automatic shutdown when the powder container reaches the set range).

Dosing coffee grinders win the hearts of most small and medium-sized coffee shops because of their reasonable price, ease of use and maintenance. However, because it is not possible to precisely control the amount of ground coffee, the amount of coffee powder taken out will be difficult to fit the handle. Excess powdered coffee will be in the reservoir waiting for the next use, which will inadvertently lose the flavor of the remaining coffee.
Automatic quantitative coffee grinder (On Demand) is a coffee grinder product according to user needs. It will adjust the amount of powder based on the grinding time setting, for example 5 seconds/1 shot of espresso. This helps to homogenize the quality of each batch of ground coffee. Therefore, most famous franchised coffee chains choose to buy electronic coffee grinders on demand.
Coffee beans are extremely diverse, each type will have a different blend, some beans are more porous than the rest, the same coffee but the hardness, moisture content today will be different tomorrow. Therefore, every time when starting the first shift of the day, the barista needs to have the task of grinding samples and testing to set the most accurate parameters.

More modern, more advanced when today, many brands have launched coffee grinders that adjust the amount of powder according to gram weight instead of grinding time. Therefore, the alignment over time may not be accurate if your shop uses several different blends. Specifically, inside the blender will be integrated a scale that weighs the powder weight in each grind, giving perfect accurate results. This machine will meet the barista's most demanding requirements for espresso quality.
Advantages: Self-quantification of this machine helps to shorten the grinding time, aligning the coffee powder before compressing to increase the service efficiency of your cafe. When the handle is placed on the holder and gently pressed on the body, the machine will grind and stop automatically within the time/reaching the previously fixed amount of powder. This helps to ensure the freshness of the coffee. Avoid residual ground coffee powder, quality loss by exposure time to air and light.
2.3. Selection by blade style
There are two basic types of grinders on the market today: flat and conical. What these two types have in common is the serrated blade to grind the coffee smaller, creating the ideal powder for espresso. Both blade types also have a fixed blade tip and a lower rotating blade.
Features of flat blades (Flat Burrs)
The parallel metal blade will pull the coffee beans into the blade through the centrifugal force of a fast-moving motor. The coffee beans will come into contact with the serration of the blade and break. Popular cutter diameters range from 50mm to 65mm, and more than 75mm for super-fast high-powered machines.

Coffee beans will be cut into smaller pieces because the lower blade contact speed makes the coffee beans penetrate smaller and smaller interdental spaces, creating a smooth powder. The disadvantage of this flat blade is that it easily generates heat when rotating at high speed. However, the uniformity of coffee beans is better when grinding with a cone.
Features of the conical blade
The conical blade makes the grinding cut vertically in the shallow part of the corner thereby pulling the coffee beans down. The coffee beans will be ground extremely small until the desired fineness is achieved. Unlike the flat blade that uses centrifugal force, the conical blade grinds coffee at a slower speed. This results in a lower heat transfer to the coffee beans and the grinder will not generate much heat that will cause a change in the coffee flavor.
Selection based on coffee grinder brand
In order to meet the needs of customers to buy espresso coffee grinders in Vietnam. Currently, many types of coffee grinders from different brands are imported and distributed in Vietnam. To ensure quality, you should buy an espresso machine from Europe. This type of machine has high durability and large capacity, durable operation. However, these machines will be expensive compared to machines from Taiwan or China.
