Hand-brewed coffee, as the name implies, is to pour hot water on the coffee powder and extract the coffee through filter paper and filter cup. the whole brewing process is about 3 to 4 minutes. As the flow rate, direction and temperature of the hot water are all controlled by the brewer, the flavor of the coffee brewed is different almost every time. Although the appliance is simple, it pays great attention to technique and experience.

What is espresso? To put it simply, Italian coffee is based on the mechanism of Italian coffee, which uses atmospheric pressure to let hot water pass through freshly ground coffee powder to extract the essence of coffee. Its most important feature is that the production time is quite short, and the aroma of coffee is strong. Compared with other kinds of coffee, caffeine is also lower.

In addition, espresso is based on espresso, so the development is quite diverse, as long as different proportions of milk are added, a series of products can be extended, such as cappuccino, latte and other rich coffee.

Differences in 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 3 minutes, while the brewing time of espresso is usually 20 Murray 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.
