Siphon coffee is extracted by immersion extraction. As the name implies, the principle is to soak the coffee powder in a container and interact with hot water for a period of time. Dissolution and diffusion to release the flavor and aroma of coffee smoothly, and the extraction is completed before the miscellaneous flavor is precipitated.

Compared with hand washing, the variation of immersion extraction is relatively small. Common immersion extraction utensils include French filter kettle, siphon kettle, and Philharmonic pressure, etc.

The ratio of powder to water in siphon coffee

The usual ratio of powder to coffee liquid is 1 2cup 10 grams 15, which means 10 grams of coffee powder produces 100~150ml coffee liquid (usually 1cup, 2cup, etc.) are marked on the siphon pot. 1cup is about 120ml, that is, about 10g of powder. The specific proportion can be determined according to personal preference.

Prepare utensils

A set of siphon pots, heating equipment (alcohol lamp, gas stove, electric halogen lamp, etc.), lighter, bamboo spoon for mixing, slightly wet rag wrung out.

First, fill the water-hook the filter element

Fill the pot with hot water and mark it with the "two cups" icon. 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.

Second, ignite-insert the pot diagonally-waiting for big bubbles

Pay attention to make sure that there is no water on the outer wall of the pot before heating, so as to prevent the pot from cracking when heating. Light the alcohol lamp, insert the upper pot diagonally, and put the rubber edge against the spout of the next pot. Soak the chain in the water in the pot. Then boil the water and wait for the pot to produce continuous bubbles. Just put the upper pot diagonally, don't let it clog the next pot, small bubbles don't count, wait for big bubbles to appear.

Third, upright-insert it into the upper pot

When large bubbles appear continuously in the lower pot, straighten the upper pot, shake it left and right and press it down slightly so that it is gently stuffed into the lower pot. After the upper pot is plugged in, you can see that the water in the next pot begins to climb up. If you have a bean grinder, you can start grinding beans now.

Fourth, let the water in the lower pot rise completely to the upper pot.

After the water has completely risen to the pot, don't worry. Wait a few seconds, wait until the bubbles that rise to the top of the pot are reduced, and then prepare to pour in the coffee powder.

Fifth, pour in the coffee powder-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 in the left and right direction, with a "strong way" of downward pressure, to "press" the coffee powder floating on the surface of the water below the surface.

6. Stir twice more.-flameout

After the first stirring, time 30 seconds, make the second stirring, and then time 20 seconds. After the final stirring, the alcohol lamp can be removed. Take a slightly wet dishcloth prepared in advance 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 lower pot touches, 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.

VII. Completion

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 brewed by hand.
