Abstract

A filter capsule for secondary filtration of extracted coffee is provided, where the filter capsule comprises a housing and at least one filter element or consists thereof. The housing comprises a bottom, at least one side wall and at least one cover or consists thereof, the at least one filter element being disposed in an interior space of the housing. Coffee extracted on a brewing strainer can be subjected to a secondary filtration so that suspended particles and emulsified oils of a specific size are separated from the coffee by the filter element of the filter capsule and a new type of coffee is produced. The use of the filter capsule for secondary filtration of coffee is therefore proposed.
