1. Source of raw materials: there are few coffee dealers in the north, and the weather is not suitable for preservation. It is recommended to buy online. Taobao has several more reliable ones. Express delivery will definitely arrive in 3 days, which is convenient and fast. No need to stock up. You can also buy it online with syrup. You should use fresh milk and try more.

2. Raw materials, the coffee taste of northerners is actually relatively light, so I suggest you choose Italy and Kona, add a few kilograms of beans in large quantities, grind half the amount of a day at a time, and grind it temporarily by hand. You can usually use a home pulverizer, which is no trouble at all. You should also add charcoal, concentrated, blue mountain and other flavors and put them into small packages. Now you have them all.

Machine, I'm afraid you can't afford it with Italian machines. Why don't you get a small mocha pot for six people, a racing pot for three people, and an electric coffee pot for home use, so 1000 yuan will come down.

4, craft, slowly, from mocha practice, cappuccino and latte have also been practiced slowly, but one thing is to control the number of guests, China people recommend the last two cups a day.

5. Quality, the quality of coffee is not only related to technology, but also related to temperature and catering, and it is gradually strengthened. It should be noted that the real good coffee is "90 degree water" and "70 degree coffee"

Besides, there should be all kinds of cakes and more side dishes.
