How fine should coffee beans be ground?

1) use the manual pulverizing button and measure the powder weight with an electronic scale. There will be an error of + /-0.2g when using manual pulverization. This is the conclusion we reached during the test, so you need to add or remove a little coffee powder to achieve the most standard weight. Some of our customers use small cups instead of handles when weighing them. You can also do this. After measuring, you can pour the coffee powder directly into the handle.

2) press powder according to your usual habit. In order not to destroy the just set amount of coffee powder, you need to use uniform strength when pressing the powder, so that the surface level of pressed powder, the overall pressure of pressed powder is moderate. No matter what method you use, you need to pay attention to the consistent method of pressing powder each time, so as to avoid the effect of making skills on the quality of coffee.

Pour the milk into the milk bubble pot, the amount should not exceed 1 stroke 2 of the milk bubble pot, otherwise the milk will overflow due to expansion when making the milk bubble.

Heat the milk to about 60 degrees, but not more than 70 degrees, otherwise the protein structure in the milk will be destroyed. Be careful! The lid and strainer cannot be heated directly. (for example, make ice foam to cool the milk below 5 degrees Celsius, of course, do not overfreeze and let the milk freeze.)

Put the lid and the filter on, and quickly twitch the filter to press the air into the milk. when you twitch, you don't need to press to the end, because you want to pump the air into the milk, so you can act on the surface of the milk; you don't need too many times. gently twitch about 30 times.

Remove the lid and strainer and scrape off the thick foam with a spoon, leaving dense hot (ice) foam.
