Qianjie Coffee talk about the basic parameters of Espresso.

The extraction time is 25 seconds, try to follow this time, unless you plan to take some different tests.

The amount of coffee powder will depend on the size of your powder bowl (single and double), requiring 8-10 grams of coffee powder for each serving of Espresso extracted.

A serving of Espresso is usually 25-35 milliliters, which can be easily adjusted by other parameters.

The 14 steps of normal unintentional enrichment.

1. Cups

Before using the coffee cup, remember to warm the cup and rinse with hot water. The hot coffee cup can better maintain the flavor of the coffee.

2. Extraction handle & powder bowl

Next, check that your extraction handle is clean and dry, keeping in mind that residual coffee grounds can affect the taste of Espresso. A wet powder bowl will also affect the extraction of Espresso, which will moisturize the coffee powder.

3. Grindability and flour content of coffee beans

Put the ground coffee powder into a powder bowl and control the degree of grinding and the amount of powder to ensure that it is not underextracted or overextracted (insufficient extraction will cause sour taste, excessive extraction will increase bitterness). If you have a bean grinder that can be accurately calibrated, it can be easily controlled. If not, please use an electronic scale.

4. Cloth powder

Tap the edge of the powder bowl so that the coffee powder is evenly distributed if you have a cloth powder tool you can use. This step is very important, it will ensure that there is no too large gap between the coffee powder, the gap is too large due to the channel effect of water, the water will gather more toward the gap during extraction, rather than evenly through the coffee powder, this will cause some coffee powder to be over-extracted.

5. Pressing powder

The purpose of this step is also to eliminate the gap between coffee powder and ensure that coffee powder is evenly distributed.

Press the coffee powder with a powder hammer to make sure your arm is exerting force vertically and evenly along the coffee powder. The usual saying is that it takes 30 pounds of pressure, and you don't have to fully comply with it. Apply force vertically to ensure that the surface of the coffee powder is smooth, which avoids inconsistent extraction.

6. Fix pressed powder

Use the powder hammer to modify the coffee powder surface, place the powder hammer on the coffee powder, and then rotate, which will eliminate the small ridges on the coffee powder surface and ensure that the coffee powder surface is flat and smooth.

7. Clean the powder bowl

Imagine that you ordered a cappuccino and drank coffee grounds in the cup. To avoid this, be sure to clean the coffee powder around and around the edges of the bowl.

8. Wash the boiled head

Before installing the handle, you should learn to clean the brewing head on the coffee machine, which will remove the coffee grounds left on it. Do not ignore this step, if there is a residual coffee grounds to enter, the final taste will be inconsistent.

9. Extract Espresso

Finally, put the prepared handle on the coffee machine, press the extraction button, and start extracting your Espresso. Be sure to extract it immediately after loading it. If you come back 2 minutes after you answer the phone, everything in front of you will be done for nothing.

10. Serve coffee

Whether the coffee machine automatically sets the extraction time, or you manually press the stop button after 25 seconds, once the extraction is complete, the coffee cup can be removed from the coffee maker tray. A cup of Espresso is finished, you can serve it directly to the guest, or you can milk and start making lattes or cappuccinos.

11. Throw away pressed powder

Remove the handle from the coffee maker and pour the extracted coffee grounds into a special box. Remember never to skip this step, after all, let the coffee grounds on the coffee machine stew, it is not easy.

12. Cleaning treatment

Rinse your handle to welcome the next Espresso.

13. Wash the boiled head

Turn on the water button and wash your head with a small brush. You need to get rid of the coffee grounds completely, or it will spoil your next cup.

14. Replace the handle

Reinstall the handle back to the coffee maker to keep the handle clean and hot and not look for the handle everywhere when making the next cup of Espresso.
