This. . . It's a bit general. It depends on how much you want to learn.

If you want to have a comprehensive understanding, I suggest you buy this book. "Coffee Know-How" is very suitable for beginners to have a comprehensive and systematic understanding of coffee.

The whole book is divided into the following parts: brewing coffee, classification and characteristics of coffee beans, making fancy coffee, making snacks, and coffee utensils.

Overall feeling: suitable for beginners. It can give people an overall understanding of coffee. It explains the issues very comprehensively. The most important thing is that it is very operable. Although it is a fancy coffee, the ingredients used are relatively basic. You only need three ingredients to make it. A variety of delicious fancy coffees - beans/powders, milk. Of course, if you still have some sugar, you can make more whipped cream, chocolate and the like. The items used in it are generally found at home by those who like coffee or baking.

Of course, if you want to learn more professionally, you have to study with a master. Well, going to various coffee shops to taste it is also one of the compulsory courses.

Let me borrow someone else's hand-made results and talk about how to use the coffee machine (from "Wreckage on a Cold Night"):

= =First of all, the espresso machine~that's it Something like a boiler (actually it is a boiler - -)... It is divided into fully automatic and semi-automatic. The fully automatic one just puts the beans in directly... The semi-automatic one requires you to grind and press the powder yourself... You can make this It is espresso, with a thick layer of coffee crema on it. It is used to make espresso (like cappuccino, latte, macchiato). They are all espresso. Some people also call them fancy coffee. (coffee) base material~

Then the American coffee machine, that is, the drip coffee machine... makes American coffee~ (Of course, using espresso hot water is also equivalent to American coffee) This How to use it~ Just put the ground coffee powder into the funnel above... Add water to the water tank... Wait slowly... - - This is super slow...

The third siphon pot~also known as Japanese coffee machine~the king of single-origin coffee (coffee made from a single species of coffee beans) is more complicated to operate = =~it uses the principle of siphon~Please Self-consciously search Baidu ~ and then click Baidu video ~ there are many introductions ~ the coffee brewed by this one is also relatively weak ~

The fourth Moka pot - - This one is usually too lazy to buy an espresso machine. .I want to drink Italian coffee again...The Moka pot is divided into upper and lower parts..There is a coffee powder bowl in the middle~Put the coffee powder into the powder bowl...press it a little (don't press too much... .Easily over-extracted) Then add water below... put it on the stove to boil... when the water below has almost turned into the coffee above... turn off the heat... this is considered to be the way it is made. Espresso bar~ It just doesn’t have much coffee creme. Many coffee shops use Moka pots to make espresso when they are too busy...= =...

The fifth French press~ This is the simplest one~ In fact, it is just a tea maker... grind the coffee powder and put it in... add 90 degree hot water... cover the lid... wait for 1 minute... then put the filter Press the filter to below the coffee fat ~ wait another minute ~ and then slowly press the filter to the bottom ~ the coffee is ready ~ the trick is... when pressing... it must be slow and steady... unless you I want to drink a mouthful of coffee grounds~
