A drip coffee machine, search the price on a treasure 100-200 RMB. There is one in Bian Xiao's office, but this pink color is really exciting. Cost = 150 (coffee machine fee)
Step 2 preparation:
This type of coffee machine needs to grind coffee beans, so the next step must be to buy a grinder that can grind coffee beans. Because it is entry-level, you can only choose manual. I checked it for you. The price is about 70 RMB, and the coffee beans are also complimentary.

The third step preparation:
The last step of the milk bubble cup, with limited budget, can only be used manually. The price of a treasure is about 40 RMB. Cost = 150 (coffee machine) +70 (grinder) +40 (milk foam cup)
The grinding thickness of coffee powder affects the extraction rate. Hand washing belongs to drip filtration brewing method, which means that the contact time between coffee powder and water is shorter than soaking, but longer than Italian concentration extraction. Hand washing must make the surface area of coffee powder enough to be extracted by water, but it should not be too fine to cause excessive bitterness.
You can start the test with moderate grinding, evaluate your coffee, and then adjust the grinding degree. If the coffee tastes a little thin or sour, grind it more. If the coffee is too bitter or lacks sweetness, try coarse grinding.
It is also important to buy a good quality bean grinder to ensure the consistency of coffee powder thickness. Inferior ground beans will grind inconsistent powder and produce a lot of fine powder, which will cause excessive extraction and ruin your coffee.
