Introduction to coffee about beginners how to choose coffee grinder skills

Some people sell beans, machines, etc. are high-end, expensive, technology is also good, but the taste of coffee is always lacking; often has a lot to do with the grinder, an ideal grinder requires less heat production during the grinding process, grinding particles to be uniform, almost no electrostatic fine powder; because if too much heat is produced, it will cause rapid loss of coffee aroma, uneven grinding will cause insufficient extraction or excessive, static electricity will have a greater impact on Espresso!

Therefore, a good grinder is still very important for the taste of coffee!

Hand-operated bean grinder

Simple shape, conical grinding tool to grind beans, function and appearance in hundreds of years almost unchanged, very with life taste!

The advantage is that there is no need to plug in, quiet, uniform particles, and no overheating! The downside is that if you grind a lot of coffee beans will be very tired! Hand-grinding beans are more suitable for family use, because the amount of coffee you drink is usually not very large, and it is not very tired to shake it with your hand. Instead, the coffee you make will taste better.

Small electric grinder--

The two blades rotate to chop the beans. The disadvantage is that they produce more heat, the ground beans are more uneven, and static electricity will be generated. It is recommended not to use coffee at home, because it has a greater impact on the taste of coffee. But for some small coffee shops, in the case of insufficient budget, you can consider, because the hand is too tired, other bean grinders and more than the budget, you can choose it!

Medium grinder--

Like flying eagle, Pegasus and other well-known, this grinder has the advantage of grinding beans is relatively large, the disadvantage is noise, static electricity, but the general coffee shop can consider buying, because it grinds the amount of beans, saving time and effort, cooking coffee is very suitable!

Top bean grinder--

This kind of grinder is very suitable for large coffee shops, because it is suitable for Espresso, with semi-automatic coffee machine, but the noise is also slightly larger, of course, for economic conditions, but also very fond of coffee is absolutely the first choice!

[Grinding essentials]

No matter what kind of grinder you use, you must master a few essentials:

1, particle size should be uniform

If it is not uniform, the coffee brewed will also taste uncoordinated. The finer the ground particles, the more coffee ingredients are extracted, and the coarser the particles, the less ingredients are extracted.

In order not to destroy the original aroma of coffee, care should be taken when grinding to make the particles uniform.

2, avoid friction heat generation

Grinding coffee beans at high speed generates heat due to friction, which can deteriorate the coffee powder or dissipate the aroma components of the coffee. Manual grinders are especially prone to heat generation, so pay attention to slow grinding.

3. Remove fine powder

When coffee beans are ground, some fine powders are produced, and if mixed in, bitter substances such as tannins are released during brewing. Fine powder is produced more in the use of electric grinding machines, and some electric grinding machines have the function of automatically removing fine powder, which can usually be removed manually. Because fine powder is lighter than normal coffee particles, as long as the ground particles are shaken and blown, they can be removed.

In addition to mastering the grinding essentials, it has an impact on the taste of coffee, and the maintenance of the grinder is also very important;

After grinding, clean the grinder immediately. The fine powder adheres to the grinder, and the coffee taste deteriorates after repeated use. Fine powder can be removed with a small brush.

In addition, the rotary grinding teeth should also be cleaned. Coffee bean grease and fine powder adhesion on it, will affect its normal operation, can be used to clean bamboo sticks or toothbrushes.
