How to match the thickness of coffee powder with the utensils? What kind of utensils are used to cook with different degrees of thickness?
Coffee is a science, and the deeper the knowledge, the harder it is to see. In addition to making a perfect cup of coffee, there are many specialties. It seems like a simple grinding, but there are many details to pay attention to. If the grinding fails, the flavor of the coffee extraction will be consumed.
First, the correlation between the degree of grinding and cooking machines and tools:
The factors that affect the flavor of coffee are not only the origin, but also the different brewing utensils, the temperature of hot water, the contact mode of hot water and brewing time. And so on are all influencing factors. And different cooking utensils also determine the thickness of bean grinding, different thickness more affect the flavor of brewing. Generally speaking, the grinding thickness of coffee beans can be divided into four types:
1. Very fine grinding: also known as "concentrated coffee grinding", "Italian grinding".
Particle size: like white granulated sugar
Suitable for brewing machines: Italian espresso machine, Turkish Epico pot.
two。 Fine grinding:
Particle size: between white sugar and fine sugar
Suitable for brewing machines: filter pot, filter paper dripping method and American coffee machine
3. China Grinding:
Particle size: between fine sugar and coarse sugar
Suitable for brewing machines and tools: siphon (air stopper), flannel filter bag
4. Rough grinding:
Particle size: like coarse sugar
Suitable for brewing machines: filter pressure pot, light drop filter pot, water drop coffee machine
Second, the degree of grinding and the change of coffee flavor:
Compared with the ground coffee beans, the oxidation rate of the ground coffee powder increases with the increase of the surface area of the contact air, the preservation time of the coffee decreases, and the flavor changes with the temperature. During brewing, coffee will also be dialyzed and extracted according to the degree of grinding, and the temperature and mode of brewing water with different degrees of grinding will also affect the flavor of coffee. Therefore, the basic law summarized is that the finer the degree of grinding, the stronger the bitterness; on the contrary, the coarser the degree of grinding, the lighter the bitterness.
Rough grinding degree
Fine
Small and large surface area
Less extraction ingredients and more
The concentration is light and thick
The bitter taste is weak and strong.
Third, the key points of coffee grinding:
Coffee beans are ground into powder, resulting in rapid oxidation due to the increase in surface area in contact with the air, and coffee oil will also be sour due to oxidation, so the degree of grinding is also one of the keys to the success or failure of coffee. The key points of coffee bean grinding are as follows:
The best time to grind coffee beans is before brewing.
The lower the temperature produced by grinding, the better.
Try not to produce fine powder during grinding
Select the appropriate grinding degree according to various cooking utensils
Fourth, cleaning and maintenance of bean grinder:
Every time you taste a cup of coffee, you can't help but wash the cups and plates, arrange the dishes and brew the machine. in addition to these, the bean grinder also needs to be carefully cleaned and maintained after each use, so that in addition to maintaining cleanliness and durability of the machine, the most important thing is that the bean grinder will smell because of grease the next time it is used. The key points of cleaning and maintenance of bean grinder are as follows:
Carefully wipe the appearance of the bean grinder.
Clean the exit of the coffee powder.
Disassemble the bean grinder regularly and clean the gears carefully. Wait for a place where it's easy to get stuck in grease.

Professional coffee knowledge exchange more coffee bean information Please pay attention to the coffee workshop (Wechat official account cafe_style) the finer the coffee powder, the high temperature and rapid manual brewing will be bitter? Is the fine powder good to make coffee by hand? The following five records are for reference and comparison only, for the brewing practice of fine powder. I like the taste of D and B very much. If you are interested, you can fine-tune and test it by yourself. It is recommended to use a small amount of fine powder.
