System for preparing a beverage

Abstract

A beverage preparation system comprises a first exchangeable capsule with a first exit face and a second exchangeable capsule with a second exit face, the second exit face having a larger diameter than the first exit face. The system further comprises an apparatus including an extraction plate having a plurality of relief elements for selectively engaging one of the first and second exit faces, and a fluid dispensing device for supplying an amount of fluid under pressure to a selected one of the exchangeable capsules, so as to press its exit face onto the relief elements, for opening the exit face. The extraction plate and the second exit face are adapted to each other such that a flow resistance of the second exit face when opened is less than a flow resistance of the first exit face when opened.
