Boutique Espresso

Espresso can have many meanings. First, it can refer to a method of coffee extraction in which hot water is passed under pressure through compacted coffee grounds to make one or two cups of coffee at a time. Second, it can refer to a degree of roasting of coffee that is darker than the dark brown of American Roast and lighter than extremely dark. More broadly, Espresso can refer to a whole range of coffee beverage making methods, including not only roasting and extraction, but also grinding and grinding, heating and foaming of milk, and traditional beverage categories. In the simplest terms, Espresso is an atmosphere, a mystery: the espresso machine is the soul and aesthetic core of cafes around the world.

What makes Espresso?

The Espresso system evolved to meet the needs of coffee shops. Aside from expensive home espresso systems with advanced features, it's impossible to make coffee-shop quality Espresso in your kitchen without spending thousands of dollars on equipment.

From the basic principle of coffee extraction, Espresso is the same as other coffee extraction methods, all of which use hot water to soak coffee powder. The difference is the pressure of the hot water. In the general drip extraction process, the coffee powder is held in a very loose state in the filter, and the water passes through the coffee powder under the action of gravity. In espresso extraction, water is forced through the compacted coffee cake.

Fast and thorough extraction creates the best coffee. If the hot water is in contact with the coffee powder for too long, the coffee will be over-extracted, and many unpleasant tastes will appear in the coffee liquid, and the good aroma and flavor of the coffee will be affected. The extraordinary thing about the espresso system is that the pressurized hot water quickly touches each coffee particle and extracts the good ingredients into the cup. Another advantage of the espresso system is freshness. Each cup of coffee is made on site in front of guests and ready to drink; in most cases, the beans are freshly ground. Other coffee extraction methods often use pre-ground coffee powder, and the coffee is placed in a large coffee pot somewhere to wait for guests to drink, and the aroma and flavor of the coffee are lost.
