Many people have such a question: what is the difference between "coffee" and "espresso"? Espresso (Espresso) or espresso is a strong type of coffee named for its rise in Italy. It is a type of coffee with strong taste. It was invented and developed in Italy and began in the early 20th century until the mid-1940s, using a human arm force pressure rod to pressurize steam. After a series of technological progress, human pressure was gradually abandoned and became what it looks like now.

It is a kind of drink made by steam pressure alone, which is made from hot but non-boiling hot water through high pressure and over-fine grinding of coffee powder with a high water / powder ratio. Due to the existence of 9 times atmospheric pressure, the extracted coffee liquid is actually composed of mesosoluble suspension with a golden layer of coffee oil Crema on the surface. These intense extraction conditions make Italian concentration the strongest coffee extraction method in the world in flavor and aroma.

Thanks to the popularity of coffee chains such as Starbucks and Costa in China, espresso (Espresso) and coffee drinks based on it have almost become synonymous with coffee in Chinese. Can not calmly say a few mouthful transliteration words such as "latte", "mocha" and "caramel macchiato" simply disqualify literary and artistic youth. However, although they are all made from coffee beans, Espresso and coffee can be said to be two completely different drinks in terms of extraction method, taste and composition, and the difference between them is no less than brandy (usually distilled from wine) and wine.

Before we talk about the difference, let's talk about the similarities between the two.

First of all, you must know that so-called "coffee" and "espresso" are made of coffee beans. Some of the coffee or espresso you drink are made from different kinds of beans, and some are made from the same kind of beans, but on the whole, no matter what kind of coffee it is, it is roasted and brewed.
