Freshly ground has nothing to do with the difference between drip coffee and espresso, although it does exclude Keurigs and similar devices. No matter what kind of coffee you’re making, you can freshly grind the beans or buy pre-ground coffee. An espresso machine forces hot water at high pressure through the ground coffee, resulting in a small amount of coffee called a “shot,” which can be added to milk, cream, water, etc. to make the various kinds of coffee shown in the picture in your article. The last kind, espresso added to water, is called Americano, but is quite different from the coffee Americans have been used to drinking (espresso has only become popular in the last few decades).

Americans are used to drinking drip coffee, which is made in a completely different way. Ground coffee is placed in a cup-shaped coffee filter over a pot, and hot water is slowly dripped through it, until the pot has several cups worth of coffee in it, which takes several minutes. A shot of espresso is only about 44mL, but a cup of drip coffee is larger, more dilute, and has a subtler taste.

There are, of course, other ways of making coffee, like the aforementioned Keurig machines, French press, Turkish coffee, moka pot, and so on, but I don’t know much about them. I also don’t know what kinds of coffee are and are not common in China and other Chinese-speaking countries.

Hi idalton, Thank you for your comment!

To be honest, I don’t claim to be the foremost authority on Coffee or a connoseiur, and normally I just order a regular coffee, but if I were to order different roasts, this is what I would say:

Light Roast – 光烤 or Guāng kǎo

（For medium light roast, you could say 中光考）

Dark Roast – 暗烤 or Àn kǎo​​

So you could shorten it to guang kao and say 要一杯光考。(Yao Yi Bei Guang Kao) For medium light roast, you could say 中光考。 For dark roast you could say,

现磨咖啡 xiànmó kāfēi – would be freshly ground or Drip Coffee.

Hope this helps!
