Brewing reason and usage of coffee brewing method-Philharmonic pressure reverse pressure method

First, why use the reverse pressure method?

Philharmonic pressure coffee production is usually divided into positive pressure method and reverse pressure method, positive pressure method, Chen Lei will not talk about it, today only talk about the production method of reverse pressure. The reason why the reverse pressure method is recommended for making coffee is that when making coffee under positive pressure, Aijiu is leaking seriously, and the coffee liquid has almost run out before the pressure is lowered, so this situation will lead to uneven extraction of coffee.

The method of making coffee by reverse pressure can ensure the stability of coffee taste.

Second, the operation method of making coffee by Philharmonic pressure.

Philharmonic pressure to make coffee, powder water than 1:12 or 1:13, water temperature 85-92 degrees, depending on coffee beans and freshness.

1. Take off the Philharmonic pressure filter, put on a round filter paper, wet it with water, and set aside.

3. Pull the handle of the Philharmonic pressure to the bottom (not all of it, leave a distance of about 1 to 5).

4. Pour hot water into the hand punch and insert a thermometer to measure the temperature.

5. When the water temperature drops to 88 degrees, the coffee beans are weighed and ground into coffee powder. Chen Lei personally uses a small Pegasus bean grinder with a grinding degree of 3.5, which is similar to that of siphon pots and manual brewing.

6. Put the Philharmonic on the gram weight, pour in the coffee powder and clear the zero.

7. When the water temperature drops to 85 degrees, pick up the hand flushing pot and add water to the Philharmonic pressure to brew coffee powder, and time it.

8. After adding the right amount of water, use a mixing rod to stir and buckle the filter to the Philharmonic pressure.

9. Use a glass pot of hot water to hold coffee, and pour out warm water.

At about 10 or 50 seconds, buckle the Philharmonic pressure backwards and drop the strainer on the coffee pot.

11. Press the handle to the bottom at a uniform speed. At this point, the Philharmonic pressure reverse production of coffee is completed.

Third, the advantages and disadvantages of Philharmonic pressure in making coffee.

Advantages: Philharmonic pressure is cheap, easy to operate, high stability, produced coffee taste clean, easy to clean.

Disadvantages: positive operation, a little coffee grounds will fall into the coffee liquid, in addition, each time the cup of coffee is less, can not be made quickly and in large quantities.
