Compared with the familiar espresso, what is the difference between the two forms of coffee? For many coffee drinkers, the definition of the two is a little unclear.

Coffee beans

a. Hand-made coffee:

Usually a single product of coffee beans as the raw material, roasting degree from light roasting, medium roasting to deep roasting are used. It is usually the degree of baking between the number of the figure below, about 9: 13.

b. Espresso:

A coffee shop's espresso recipe, called House Blend, is usually heavily used in espresso drinks such as cappuccinos, American coffee and lattes, most of which are roasted deep to go with milk and hot water. Making this kind of coffee can only be grinded by a professional bean grinder, which is also an important foundation and key to making high-quality espresso.

Espresso beans are roasted between 13 and 16 in the picture above.

2. Preparation method

a. Hand-made coffee:

Basically, most of the hand-brewed coffee is extracted by using a filter cup, that is, it is extracted at an atmospheric pressure. Even if you use cooking utensils such as mocha kettle and Ailo pressure, the pressure during extraction will only reach about three atmospheres at most.

b. Espresso:

When extracted with an Italian coffee machine, the pressure of the machine will make the state of the extraction reach 9 atmospheres. The pressed powder in the filter cup is under a heavy pressure of 133kg, which releases a large amount of coffee substance and tastes thicker. It is suitable to make lattes with milk or American coffee with water.

Third, the difference of CC number.

a. Hand-made coffee:

Generally, the quantity provided is about 150~300cc. (increase or decrease according to the ratio of gouache to flour)

b. Espresso:

Generally, the quantity provided is about 30~60cc. (increase or decrease according to the ratio of gouache to flour)

Fourth, the difference of caffeine

In the case of the same amount of powder and grinding thickness, because caffeine is a water-soluble substance, the longer it takes to brew, the more caffeine is released.

The brewing time of single coffee is usually 1: 3 minutes, and that of espresso is usually 20: 30 seconds, so the caffeine content of single coffee is higher under the condition of the same amount of powder and grinding thickness.

It can be seen that the caffeine content of coffee extracted for a long time, such as ice drop coffee and cold extract coffee, is much higher than that of other coffee.

You can see that there is a great difference in the concentration between hand-brewed coffee and Espresso coffee liquor. when milk is added to a single coffee, it will be covered with milk to cover the aroma and flavor of the coffee itself, which is not suitable for use in blending.

V. the conclusion of the difference

Can individual coffee be brewed by machine after all? Yes, but all the cooking parameters have to be adjusted. Finding suitable cooking parameters with individual coffee beans is also an espresso that can brew single origin of good quality.

Can the espresso beans be made by hand? It's okay, too. But for deep-roasted espresso beans, parameters such as water temperature and grinding thickness should also be adjusted.

Please remember, all the brewing methods and utensils are to provide better coffee, coffee exists for people! Coffee can make everything possible.
