The secret of the success of coffee flower drawing

A cup of perfect plaster-like Espresso

Paste Espresso means the way it flows from the machine nozzle into the cup, just like soy sauce paste! You must have poured soy sauce and soy sauce ointment. You can feel the difference. To get a paste-like espresso, you must control the correct water temperature, the right pressure, and so on. The whole cup of paste-like crema espresso is very strong and a little sweet, after drinking it, the feeling of returning sweet can last 40 to 50 minutes!

In the book "Espresso Coffee The Science Of Quality" written by Dr. IIIy& Viani, espresso is defined as--

Coffee bean powder 6.5 ±0.5g

The temperature of boiling water is 90 ±5 ℃.

The boiling water pressure is 9 ±2bar

Cooking time 30 ±5sec

The scientific basis can only be used as a reference, because there are too many factors to pay attention to when brewing a cup of espresso, not to mention the air pressure, geographical environment, milk quality, etc., so the amount of coffee powder, brewing water temperature, brewing water pressure, brewing time can all be changed according to the actual local conditions, but the only thing that cannot change is a perfect Espresso taste-mellow, smooth, not scorched, not bitter.

Most experts would recommend that the time to soak a cup of espresso is 20 to 35 seconds. Wecare, a famous Taiwanese coffee master, believes that the time should be between 25 and 27 seconds on the basis of years of experience. Because you should note that these 20 or 35 seconds are counted from the time you open your help, not when you see the coffee coming out! When you turn on the pump, it will take about five seconds for the coffee to start flowing out. If the cooking time is less than 25 seconds, the cream you get will be very light, which means excessive extraction.

Second, choose high-quality machines

If you are the first time to open a coffee shop, you may not even know how to pick a coffee machine. Just like a car, each one has four wheels. what's the difference? Of course, this is a joke, but there will be a difference of one or 2 million between cars, while the difference between coffee machines is about tens of thousands.

However, I believe that no one will care just because it is "only" more than NT $100,000. So there are many places where we must know about the coffee machine. What are the main factors to consider when choosing a high-quality coffee machine?

1. Is the stability of the machine good?

two。 Is the steam outgassing enough?

3. Is the dryness of steam good?

4. Is the reheating speed enough?

5. Is it easy to operate?

6. Whether all the control buttons and knobs respond well.

7. after-sale service

After fully considering the above seven factors, and then considering the decoration format of your store, including location, space, process and so on, you can choose the Italian coffee maker that suits you!

Third, choose fresh coffee beans and do not believe in famous brands

Beans must be roasted within five days of fresh beans! For more than seven days of beans, the aroma and taste of fresh beans will be completely lost, and your espresso will not be paste. If the beans are not fresh, the taste of coffee is dull. So, if you want to make coffee instead of espresso, you only have two choices:

1. Choose coffee beans with a certain level of local roasters.

two。 Bake beans at home by yourself.

Fourth, the production of milk foam:

1. Pour the milk into the milk bubble pot, and the amount should not exceed 1 / 2 of the milk bubble pot, otherwise the milk will spill over due to expansion when making the milk bubble.

2. Heat the milk to about 60 degrees, but not more than 70 degrees, otherwise the protein structure in the milk will be destroyed and the milk flavor will be lost. The actual situation varies from place to place, so it is necessary for local baristas to determine the best temperature of local milk. Mr. Wang Jiannan, a famous coffee technician, after repeated experiments, it is found that the best temperature of milk in Beijing should be about 65 ℃, not more than 70 ℃, otherwise the taste will be dry, astringent, not mellow.

How to determine the best temperature of local milk?

The answer is: a barista makes, tries and tastes repeatedly, the foam is big, the taste is dry and the taste is not mellow. It is not suitable to make the perfect Espresso coffee.

B take the product to the relevant departments to determine whether the nutrients are lost.

3, cover the lid and the filter, quickly twitch the filter to press the air into the milk, there is no need to press to the end, because it is to pump the air into the milk, so as to act on the surface of the milk; the number of times is not too much, gently twitch about 30 times.

4. Remove the lid and strainer and scrape off the thick foam with a spoon, leaving thick hot (frozen) milk.

5. The most important key to espresso-- talents
