Many months ago, we bought a Tchibo coffee machine. It uses a similar exactly the same concept as the Nespresso coffee machine. You pop a capsule that contains the grounded coffee into the machine, put a cup under the nozzle, press the button and voila, a steaming cup of coffee is there for you in about 1-2 minutes.
The hacker sense kicked in and had to try to get something going. After a couple of false starts, I got something that is workable and produce reasonable coffee.
The following some simple steps that I have used to reused the capsules again.
The first thing you need to do is to get a capsule that you already have used and open it up with a sharp knife. I used a pairing knife with a sharp point. Carefully, I pierced at an area just inside the lips of the capsule and work the knife around the edge. I used a gentle sawing motion as I move around. The plastic top came away quite easily.
Once the top is removed, the capsule needs to be dissembled and cleaned. Be careful to do the dissembling over a sink as the used coffee could spilled out. It could get quite messy. With in the capsule, there are two plastic filters. The top plastic filter can be lifted out to exposed the used coffee grounds. The used coffee grounds need to be removed. At the bottom of the capsule, there is a filter there. This also needs to be taken out for cleaning.
When the two filters and the capsule itself is cleaned, it can be assembled. Began by inserting the bottom filter back into the capsule. Now the usage of the coffee is next. Besure to fill as much coffee as you can fit in. I have used a small tool to jam the coffee grounds into the capsule. I have found that the flavour and the aroma is better as well when grounds is tightly packed. The top filter can also be placed on top.
Prepare a piece of aluminium foil that is big enough to cover the top of the capsule. The piece of foil need to be folded over the edge of the capsule to form a tight seal. Depending upon the strength of your foil, care need to be taken not to tear any part of the foil. Doing so may caused some of the coffee grounds to escape from the capsule and it end up in your drink.
Placed the completed capsule that has covered by the aluminium foil into your Tchibo and press the button. It will take some effort to get the combination right, but the flexibility it gives you will be fantastic.
