Selection and purchase of Coffee utensils: the Choice of hand washing

For professional baristas, please follow the coffee workshop (Wechat official account cafe_style)

"I'm a teapot, fat and short."

A nursery rhyme outlines the traditional shape of the teapot. The pot in a boutique coffee shop is not a vessel used to hold coffee, but an important tool for hand extraction. With the popularity of the third wave, the public's awareness and demand for "original flavor" has increased. As a matter of fact, any coffee, including those sold on supermarket shelves, can be processed by hand. However, with shoddy raw beans, or improperly roasted coffee made by hand extraction, the shortcomings will be exposed.

"come and take a look at the handletter I brought back when I was traveling to Taiwan! The spout of this pot is so thin that it can pour out a fine column of water effortlessly. It was invented by some hand Chong da person. With it, hand-brewing coffee will no longer need technology, even if you close your eyes can succeed, hehe. "

The measuring cup can also make delicious coffee.

Enthusiasts talk eloquently about this metal pot named after the designer. In fact, the author has tried it before. A hand-flushing pot is just a container for "filling and pouring water". The so-called design is nothing more than the difference in thermal insulation function, capacity, size and shape of the outlet. If you understand the meaning of extraction and the rhythm of water injection, you can also make delicious coffee with a common measuring cup.

"first of all, make a hole in the middle of the coffee powder ball and rotate it slowly clockwise with hot water of about 90 degrees. Circle from the inside out and go back to the middle. You can cycle three times in a row. "

Listen to him instruct others thoughtfully. Like the martial arts mind method, it is also like when you were playing video games when you were a child, entering "up and down, left and right" within a limited time in exchange for the secret skills of infinite life. The sentence he recited contains a number of scientific principles. However, depending on the formula alone, ignoring the actual state of the bucket of coffee powder, such as expansion, water flow, and so on, the quality is difficult to be stable.

The key to flavor and water flow of coffee powder

"making coffee by hand is like making a tea bag." I demonstrated water injection with a hand flushing pot made of enamel (that is, enamel). It's warmer than any metal pot.

"every grain of coffee powder can be regarded as a small tea bag. To make it taste, not only the cooking time is sufficient and the water temperature is high enough, but also the flow of water is very important. What is the use of the rope on the tea bag? We can't pull with coffee powder tied up, but it's not elegant to stir with a teaspoon. The only way is to hit it with a water column to stir the coffee in the funnel. Brew coffee with factors such as the roughness of grinding, water temperature, the ratio of water to coffee, and extraction time. "

"the spiral lines on the funnel must have caused a whirlpool, right?" The guest asked curiously.

I looked at the washbasin that was draining water and said, "the direction in which the water rotates is affected by the earth's magnetic field." Do you think this small pattern can change the laws of nature? This is just a propaganda trick of the manufacturer. "
