Abstract
The invention relates to a coffee machine for brewing a hot drink, in particular, a coffee drink, by means of a portion capsule with a capsule lid and a capsule base, comprising a pressurized water device, a portion capsule holder and a controller. The portion capsule holder is provided with two relatively-displaceable puncture means, which pierce the capsule lid and the capsule base on or after insertion of the portion capsule in the portion capsule holder, such that hot water can enter the portion capsule through the capsule lid and the drink escapes through the capsule base from the portion capsule. The controller is provided for the provision of three differing pressures for the pressurized water, for example, for brewing espresso, white coffee and filter coffee. The capsule base of the portion capsule can comprise a pre-weakened spot.
