To have coffee beans, you need a grinder, or you can go to a nearby coffee shop and ask for help grinding them. Generally, a processing fee will be charged (between 10 yuan and 50 yuan). If you don’t charge, of course you will be charged. Okay, but if you let someone else grind it for you, then you have to drink it in a short time, 15 to 30 days is better) because the ground coffee powder easily dissipates its original aroma, which affects the quality of the brewed coffee. It will have an impact on the taste. You can also buy a grinder yourself (available in coffee supply stores). The price ranges from high to low, and there are manual grinders and electric grinders. You also need utensils for making coffee. You can buy an Italian pot, also called a Moka pot. The cheapest one can be bought for less than 200. You also need rock sugar powder. The advantage of rock sugar powder is that it will not change the original taste of the coffee. So all coffee uses rock sugar powder, and you also need creamer powder (of course it’s better to have special milk for coffee). If you like black coffee, then you don’t need to buy sugar or milk. If you pay attention to good looks, you can buy a few more good-looking cups, including glass cups. By the time you can drink coffee, the items purchased in the whole process will not exceed one thousand yuan. Of course there are many. Hope this helps.
