Analysis of homemade coffee: siphon pot

Syphon pot (commonly known as "glass ball" or "siphon type") is a simple and easy to use coffee brewing method, and is also one of the most popular coffee brewing methods in cafes. Although the siphon pot has the nickname of "plug wind type", it has nothing to do with the siphon principle, but uses the water to generate water vapor after heating, causing the principle of thermal expansion and contraction, pushing the hot water of the lower sphere to the upper pot, and then sucking the water of the upper pot after the lower pot cools down-sounds very mysterious? Not at all. Follow the steps below and you will understand!

The basic appliances required for siphoning coffee are as follows:

Siphon pot set, alcohol lamp, lighter, bamboo spoon for stirring, wrung wet cloth

Process:

Step 1: Fill the water-hook the filter element

Fill the lower pot with hot water until marked with the "two cups" icon. Put the filter element into the upper pot, pull the end of the chain with your hand, and gently hook it on the end of the glass tube. Be careful not to release the hook suddenly, so as not to damage the glass tube of the pot.

Step 2: Ignition-Insert pot obliquely-Wait for big bubbles

Light the alcohol lamp, insert the upper pot obliquely, and let the rubber edge press against the spout of the lower pot (rest assured, the upper pot will not fall) so that the chain is soaked in the water of the lower pot. Then boil the water and wait for the next pot to bubble continuously. The pot can be placed obliquely, do not let it close the pot, small bubbles do not count, wait for the big bubbles to appear

Step 3: Righteousness-Insert into the upper pot

When large bubbles appear continuously in the lower pot, straighten the upper pot, shake it gently from side to side and press it slightly downward so that it is gently inserted into the lower pot. When the upper pot is plugged in, you can see that the water in the lower pot starts to climb up and then start grinding beans!

Step 4: Let the water in the lower pot rise completely to the upper pot

After the water rises completely to the top pot, wait a few seconds, wait for the bubbles rising to the top pot to decrease, and then move the alcohol lamp away from the center of the pot and warm the pot at the edge.

Step 5: Pour in coffee powder-stir (left and right)

Pour in the ground coffee powder, gently stir it left and right with a stirring bamboo spoon, and evenly spread the coffee powder into the water. Start the timer at the same time as the first stir.

Stir gently and avoid violent stirring. If it is fresh coffee powder, it will float on the surface to form a layer of powder. At this time, the coffee powder needs to be stirred, and the flavor of coffee can be completely extracted. The correct stirring action is to move the bamboo spoon left and right, with a downward pressure "strong road", floating in the surface of the coffee powder "pressure" into the water below.

Step 6: Stir twice more-turn off

After the first stir, time 30 seconds for the second stir, and then time 20 seconds for the final stir-remove the alcohol lamp. Take a slightly wet cloth prepared in advance (already wrung dry) and gently wrap the side of the lower pot from the side. Do not let the wet cloth touch the place where the alcohol lamp flame contacts at the bottom of the lower pot to prevent the lower pot from cracking. At this time, you can see that the water in the upper pot is quickly "pulled" to the lower pot. If your coffee is fresh enough, the next pot will have a lot of light brown foam.

Step 7: Complete

After coffee is sucked into the lower pot, hold the upper pot with one hand and the handle of the lower pot with the other hand, gently shake the upper pot from side to side, and then pull the upper pot apart from the lower pot. Pour coffee into a warm coffee cup and enjoy a cup of your own brewed coffee!
