Nespresso is the first company to introduce pod based coffee brewing to the world in 1974. They represent our premium supplier for pod based office coffee supply.
Nespresso’s hermetically sealed capsules are made of aluminum foil. Depending on the Nespresso machine being used, the flat top of the capsule is pierced when inserted into the machine and the compartment lever is lowered. Some machines make a single large hole, and others make a number of smaller holes. When the machine is activated it pumps hot water under high pressure into injector holes poked into the narrow end of the capsule upon insertion. This causes the flat bottom of the capsule to bow in, as this is made of thinner foil than the rest of the capsule. The base of the capsule holder (on which the capsule sits) has a number of raised squares which cause the foil to rupture at these points. The brewed coffee exits the capsule through these rupture holes and flows through a funnel nozzle into the coffee cup.
