Coffee oil, coffee beans, concentrate, mix oil, okay? espresso.

Fancy coffee, foam is made of milk. Ordinary instant coffee belongs to fast food in coffee, which is convenient but not recommended to drink more. Good coffee beans are now ground into powder, then use high humidity and high pressure extraction to extract espresso ESSPRESO (Italian style), or use a leaky pot to make ordinary coffee (American style), and then pour milk foam, caramel, chocolate powder, cinnamon powder and other materials on top to become fancy coffee. Generally speaking, extra-espresso with foam is a cappuccino. Plus caramel is caramel macchiato, and so on. But they all require a small cup of good coffee as the foundation.
