Too often it happens that we insert a compatible capsule into our machine and strain the lever too hard when closing it, even risking breaking it.
What happens to the capsule after inserting it?
It is pierced on the back by some needles, causing holes, which will allow water to enter. The capsule is then pierced on the front to allow the drink to be dispensed.
Frontally, there are absolutely no problems, because in all cases, or almost all cases, the capsule is enclosed by a light aluminum foil, which is very easy to pass through.
Instead, the problem exists at the back of the capsule, when the capsule is not optimally designed.
In fact there can be two types of compatible:
This one in the picture above, as you can clearly see, is not pre-drilled, that is, it does not have any kind of hole in the back. Having a full, thick bottom will make it more difficult for the needles to pierce the capsule. As a result, straining the machine too much when closing the lever can cause it to wear out much faster, or even cause it to break.
The second, on the other hand, is pre-drilled, that is, it has clearly visible holes in the bottom, which facilitate the entry of needles. In this case, there is no risk of either breaking the machine or cracking the capsule inside it. All Caffè Ernani capsules are designed in this way. find out more >>
If the capsule has small holes in the bottom, can the coffee spill out?
Absolutely not! The coffee does not come out of the capsule and in no way comes into contact with oxygen, which would cause it to oxidize. This is because the capsule is also barriered on the back with an aluminum foil. With this system you make it self-protected, that is, your coffee inside is protected from any external agent and does not need additional protective packaging, thus avoiding an additional waste material, with a little care for the environment.
It is thus protected from any contact with the outside world, and the coffee inside is thus kept fresh and intense even for a long time.
Unfortunately, capsules are often created without considering the best available technology, primarily to try to keep the price as low as possible, but resulting in more wear and tear on a far more expensive component: the machine.
We at Caffè Ernani wanted to give you this information just to help you figure out what might be the best choice for you.
And are your capsules closed-bottom or pre-drilled?
