I´m sure others have figured this solution out but nobody posted
it here but i wanted to share it.
I got tired of the blends nespresso offers and gave it a go to try to refill them with other blends,
and well yes im a cheap bastard also since they do cost much x capsule.
I tend to use the capsules 2 or 3 times since they poke new holes in the back but most times i seem to manage put it in so it uses the same holes again without even trying to do that.
Step 1: Preparation
Take the capsule and carve off the metallic film following the inner ring and then empty and rinse it.
Step 2: Filling
Fill the capsule with about 1.5 - 2 teaspoons of your favourite espresso blend don´t
pack it to hard or the machine will struggle and the coffe will taste bad.
Step 3: Sealing
Take a piece of foil and cut it so you have some spare
and then tuck it neatly under the edge and boom your done.
Step 4: Brewing
Now all you need to do is brew your coffe and enjoy it,
you might have packed the coffe to loose or to tight just try
again and you will get it right.
It´s very easy and way cheaper then the "originals".
