Siphon pot professional barista coffee brewing method of siphon pot operation and matters needing attention

[introduction] siphon pot, commonly known as plug-wind pot or siphon coffee pot, is a simple and easy-to-use method of coffee brewing, and it is also one of the most popular coffee brewing methods in cafes.

In 1840, a glass test tube in a laboratory triggered the siphon coffee maker's invention. the British took the test tube used in Biya's chemical experiment as a model to create the first vacuum coffee pot. Two years later, Mrs. Bachang of France improved the kettle with a little spring in shape, and the familiar upper and lower convection siphon pot was born. The siphon coffee maker lived in France for a long time, but never got a good chance to be very popular. It became popular for the first time when it was brought to Denmark and Japan in the mid-20th century.

Most people often have little knowledge of it, or even have the wrong impression, there are usually two extreme views, one is that some people are cautious and frightened about it, and what about the other? It is thought that using a siphon coffee maker is nothing more than boiling the water and stirring the coffee powder; in addition, some people think that the siphon coffee pot looks very dangerous, but as long as it is improperly used, every method of brewing coffee has hidden dangers.

Principle.

Although the siphon kettle has a siphon nickname, it has nothing to do with the siphon principle, but uses water heating to produce water vapor, causing thermal expansion and cold contraction, pushing the hot water from the lower sphere to the upper pot, and then sucking the water back from the upper pot after the lower pot cools.-does that sound mysterious?

There are also many people who like the precision of siphon cooking with a touch of laboratory flavor. Watching the water rise as the water boils, the coffee extracted into black drops, step by step in the hands of the coffee maker. Using an Italian coffee maker often leaves part of the process to a machine, and siphon coffee seems to satisfy some people who like to do-it-yourself DIY.

Steps of siphon pot brewing coffee

Fill the water and hook the filter element.

Fill the pot with hot water and mark it with two cups of icons. Put the filter element into the pot, hold the end of the chain with your hand, and gently hook it to the end of the glass tube. Be careful not to release the hook suddenly, so as not to damage the glass tube of the upper pot.

Light a fire and wait for a big bubble.

Light the alcohol lamp and insert the upper pot obliquely so that the rubber edge is pressed against the spout of the next pot (rest assured that the upper pot will not fall off) so that the chain is soaked in the water. Then boil the water and wait for the pot to produce continuous bubbles.

Pour in coffee powder

After the water has completely risen to the pot, don't worry, wait a few seconds, and then prepare to pour in the coffee powder after the bubbles in the pot decrease a little.

Stir left and right

Pour in the ground coffee powder and move it around with a bamboo spoon to evenly remove the coffee powder into the water. The timing starts at the same time as the first stirring. Stir gently to 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 so that the flavor of the coffee can be completely extracted. The correct stirring action is to move the bamboo spoon left and right, with the strength of downward pressure, to press the coffee powder floating on the surface of the water below the surface.

-stir twice more.-flameout.

After the first stirring, time 30 seconds, make the second stirring, then time 20 seconds, make the final stirring, you can remove the alcohol lamp. Take the pre-prepared (wrung-dry) slightly wet dishcloth and gently wrap the side of the lower pot from the side to prevent the wet cloth from touching the place where the alcohol flame at the bottom of the pot comes into contact, so as to prevent the pot from breaking. 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, there will be a lot of light brown foam in the pot.

Enjoy your coffee.

After the coffee is sucked into the lower pot, hold the upper pot in one hand and the handle of the lower pot in the other, gently shake the upper pot to the left and right to pull out the upper pot and the lower pot. Pour the coffee into a warm coffee cup and enjoy the mellow coffee that you have prepared by hand.

Be careful

Brewing coffee in a siphon pot tends to be lighter than a follicle, because some of the water in the tube of the upper pot does not flow to the upper pot to come into contact with coffee powder. In addition, due to the alcohol lamp has been heated, inclined to high-temperature extraction, so it is easy to make bitter or astringent taste excessive extraction and become stronger. The solution is to stir the coffee powder or thoroughly control the extraction time.

After making coffee in a siphon pot, it should be cleaned in time, especially the filter cloth, which should be properly preserved.
