The NESPRESSO®capsules must not be damaged
before use.
Deformed or torn capsules may become jammed in the
appliance and damage it.
Each capsule contains exactly the correct amount of ground coffee
for one cup.

minium capsule (A) all qualities
and flavours of the freshly
roasted coffee (B) are retained
for at least nine months.
A high-pressure pump (19 bar)
ensures that all the flavours of the
espresso develop and that a fine
crema forms.
Coffee is extracted through the membrane (C) directly to the coffee
outlet of the machine.
