Volcanic flushing and cooking technique

The method of volcanic flushing originated in Japan and is more suitable for deep-roasted coffee beans. It uses the carbon dioxide in beans, and after many times of steaming, the coffee powder bulges like a volcanic eruption, so deep-baked beans are more suitable because they contain more carbon dioxide.

Flannel and V60 are mostly used in volcanic flushing, because the middle powder layer is very thick, so it is mainly filled with water in the middle about the size of an one-dollar coin. The key point of the first half of volcanic thrust is full extraction without destroying the powder layer. The second half is uniform water injection, in order to prevent excessive extraction in the middle, play a dilution role.

Advantages: coffee taste mellow, with mellow and strong body, sweet obvious.

Disadvantages: because the first one of the volcanic flushing is over-extracted, while the last two is underextracted, the coffee liquid is very uneven, so it needs to shake well after flushing, so that the two "failed" coffee liquids are mixed together to form a perfect coffee. However, shaking well for a long time will cause the temperature to drop, and if you want to keep the temperature directly extracted with high temperature, it will lead to dry coffee.

Flushing and cooking technique by loose house method

The Matsuya method also originated in Japan, where the inventors used the brewing method to extract only the delicious ingredients from the coffee.

Use a spoon to dig a big hole in the coffee powder, about 30cm from the noodle, pour water from the middle until the coffee liquid begins to drip, then draw a circle like a circle to wet the coffee powder and cover it with steaming. After 3 minutes, uniform and uninterrupted water injection began. Stop filling when the coffee liquid reaches half of the coffee pot, and then add hot water to dilute it.

Advantages: even after a period of time, the flavor of coffee will not change much.

Disadvantages: some friends say that because the extraction time is too long, the flavor will evaporate a lot. So there is no great change in the flavor of coffee. Do you think this is its disadvantage or advantage?

Stirring and cooking technique

Why is the mixing method so popular? On WBC in 2012, Matt Perger became popular in Europe, America and Australia after it was used and won the championship of that year.

In the stirring method, you need to grind the coffee powder to a very fine size, then pour in about 50g of water, stir evenly back and forth in the direction of the cross, make the coffee powder fully contact with the water, and then fill it in 30 seconds. Complete the water injection in 2 minutes. The deep-baked beans need to be steamed for 15 seconds and then filled with water for 1 minute and 30 seconds.

Advantages: the mixing method can amplify the advantages of the coffee beans, especially enhance the taste of the coffee beans, and will not be too thin.

Disadvantages: although its flavor is more obvious, its return is weakened a lot. And this method has high requirements for the quality of coffee beans, if you use poor coffee beans, it will only infinitely magnify its bad flavor. In addition, because the grinding degree of coffee powder required by this method is very fine, coupled with sufficient stirring, it is easy to over-extract if it is not properly mastered.

Drip flushing and cooking technique

Drip method, as the name implies, is to brew in the form of dripping water. Just like the hourglass, dripping bit by bit into the coffee powder, it is completely delicate and time-consuming!

First, the coffee powder is pre-soaked and moistened with a little bit of water. when the coffee powder is dripped almost 1 stroke 3, you can start to inject water, stop when the water level of the coffee powder reaches the top, and inject water again when the water level drops to half.

Advantages: drip method can make coffee beans sweet and avoid sour and bitter tastes.

Cons: it requires a very stable grip and patience. It can be said that all the sour and astringent taste of the coffee it removes is handed over to you. Some friends say that removing the sour and bitter taste will also make the flavor of the coffee not so complete.

The method of flushing and cooking in the academic school

The academic method is the most commonly used method of brewing, and because of its stability, it is also one of the first choices for most coffee lovers. Its method of operation is very simple, injecting water from the center, then steaming, and then slowly injecting water again from the inside to the outside after the collapse. But this method requires more demanding hand brewing pot, which requires delicate, vertical, stable and uniform water flow, so that a good cup of coffee can be brewed.

Advantages: academic cooking method is very stable, suitable for most filter cups and beginners.

Disadvantages: similarly, its advantages also contribute to its disadvantages. Many coffee lovers think that this brewing method is too stable to form their own style and characteristics.
