So in terms of health, practitioners in the industry recommend drinking hand brewed drinks first. Of course, it doesn’t mean that you can’t drink concentrate. After all, “discarding the dosage and talking about the efficacy is just a hooliganism.” You can drink espresso, and it doesn’t matter how many cups you have in a day (based on a 30ml cup). However, it is recommended that drinking more hand brewed drinks will be healthy.

Espresso is a type of coffee with a strong taste. The method is to use 92 degrees Celsius hot water and high pressure to rush through very finely ground coffee powder to brew the coffee.

It was invented and developed in Italy in the early 20th century, but until the mid-1940s, it was a drink made solely through steam pressure. He invented the spring piston lever coffee machine and successfully commercialized it, transforming espresso into the drink we know today.

Defined from a qualitative perspective, espresso has a thicker texture than drip coffee and contains more dissolved substances per unit volume than drip coffee; usually the supply is measured in "portions" ( shot) to calculate. Espresso is chemically complex and fickle, and many of its components break down due to oxidation or lowering of temperature.

One characteristic of properly brewed espresso is the presence of crema, a reddish-brown foam floating on the surface of the espresso. It is composed of vegetable oil, protein and sugar. Coffee cream has a combination of emulsion and foam colloid elements.

Through the short-time and high-pressure brewing process, the unique flavor of a cup of coffee is concentrated and is more intense than other brewing equipment. However, due to the short quenching time, the caffeine content is less.
