Espresso means "fast" in Italian, referring to a concentrated coffee obtained through high-pressure, short-time extraction. It originated in Italy and, alongside fashion and cuisine, is considered one of the country's three national treasures. Early espresso tasted bitter with a burnt note, and it was not until the 1940s that its flavor and quality underwent fundamental improvement. In China, terms like 浓缩咖啡, 意式浓缩, and 香浓咖啡 all refer to the same thing—Espresso. Compared with pour-over, espresso offers a completely different taste experience: it is hot and highly concentrated, and is finished before it has time to cool, making it hard to distinguish flavor layers across high, medium, and low temperature stages as one would with pour-over. High-pressure extraction also produces a unique "crema," giving it a distinctive mouthfeel. The quality of a cup of espresso depends largely on the espresso beans chosen—the roast level, origin, and variety all influence the final taste. However, rather than being drunk straight, espresso is more often used to make drinks like Americano, latte, and cappuccino. Therefore, when choosing home espresso beans, it is best to pick a type that can accommodate a variety of coffee flavors. [more…]

When extracting espresso, you may sometimes notice small holes on the surface of the puck, or coffee liquid spraying out from the bottom of the portafilter, with an unpleasant sharp acidity on the palate.

Pre-infusion is a frequently discussed feature in espresso extraction. Simply put, it involves soaking the coffee bed with a small amount of hot water or a low-pressure flow before the main high-pressure extraction begins, giving the coffee grounds time to degas and expand. Many people feel that their espresso is already good enough and that pre-infusion seems optional, but in specific scenarios, it can genuinely improve extraction quality. This article starts from the principles of pre-infusion, explaining how it increases extraction yield, reduces channeling, and which coffee beans are suitable for using the pre-infusion function.

What exactly is the difference between single-origin coffee beans and blended coffee beans? Simply put, single-origin beans come from a single origin or estate and carry a distinctive regional flavor; while traditional espresso mostly uses dark-roasted blended beans, pursuing richness and intensity.

The golden, dense layer of oil on the surface of an espresso, known as crema, is regarded by many coffee lovers as the soul of a good espresso. Where exactly does this layer of foam come from, and what conditions affect it?

To make a delicious espresso at home, choosing the right coffee beans is the first step. Espresso machines use high-temperature and high-pressure extraction, with a brewing time of only twenty to thirty seconds, which means light roasts tend to be sour and dark roasts tend to be bitter, making medium to medium-dark roasts a more reliable choice.
