The method of volcanic flushing comes from 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.
Then which beans are more suitable for volcanic flushing?
Using a single bean with a deep baking degree, draw a circle in a small area in the center (the size of a silver coin), resulting in a process of repeated steaming. The reason for using fresh deep-baked beans is that deep-baked beans can emit enough gas, so it is convenient to observe the state of the steaming package. Qianjie coffee in the usual play this way, the usual bean is to choose gold Manning, because this bean will be roasted too deep, a water injection of coffee powder bulging like a volcanic eruption.
