The principal of the " Senseo" is similar to the "espresso-system"
which is well know in the hotel and restaurant industry.
The coffee pads always contain fine ground cofee, which
is mostly longer roasted than regular coffee. make sure you always
use fine ground coffee for the best results, preferably "espresso" coffee.

Using medium or coarse ground coffee will influence the taste of your
coffee.
