The powder of capsule coffee is directly ground from roasted coffee beans, so the principle of making capsule coffee is the same as grinding coffee. Want to drink authentic ground coffee but have no time, coffee capsules are the best choice.
The coffee machine automatically heats and pressurizes the water, pierces the capsule at the same time, and uses high-pressure steam to extract the coffee powder in the capsule, so that a cup of fragrant coffee is finished, and the taste is basically the same as that of freshly ground coffee.
The coffee brewed in this way usually belongs to Espresso (espresso). A cup in the morning can refresh you, but it is bitter (different capsules taste different), and not everyone likes it.
The history of coffee capsules:
Coffee capsule was born in 1976. When making this capsule, coffee beans are specially treated to make coffee powder and sealed in an aluminum platinum space similar to jelly. At the same time, the capsule is filled with non-toxic inert gas to prolong the shelf life and sterilize again. When you need to brew coffee, you can put this coffee capsule into a special capsule coffee machine and press the brew button without any other operation.
Advantages of capsule coffee combined with capsule coffee machine:
1, convenient. Simple operation, any novice can easily make a cup of espresso;
2. clean. Without complicated cleaning, coffee recycling capsules can be directly brewed;
3. health. Health and environmental protection, using the most stringent standard technology in Italy, and the revolutionary system of packaging coffee and filling nitrogen with international patented space capsule technology, overwhelming all current production technologies. Put it directly into the machine without unpacking, which is convenient for recycling after cooking;
4. major Under the protection of fully sealed nitrogen-filled packaging, it can effectively keep coffee fresh and prevent oxidation, so that the storage period can reach 2 years;
5. The quality is stable. Semi-automatic coffee machine adds powder manually every time. Different people have different powder filling strength. Even the same person, at different times, powder stuffing will change, because human variables lead to unstable coffee quality. Capsule coffee is on the same production line, and automatic powder filling can ensure the stable quality of each cup of coffee.
