A brewing device for a machine for preparing beverages, in particular coffee or tea, in which the brewing device comprising a brewing chamber having a longitudinal axis, a frame having two walls arranged on opposite sides of the brewing chamber, and a fastening device. The fastening device is configured to releasably couple the brewing device to a support body in the beverage preparation machine and comprises a lever release device hinged to the frame to rotate about an axis transverse to the longitudinal axis between a normal coupling position, in which the lever release device stably holds the brewing device on the support body, and a release position, in which the lever release device allows the brewing device to be released from, or mounted on, the support body.

A system and method for reducing the amount of caffeine in an existing volume of brewed coffee. The brewed coffee contains a predetermined level of caffeine. To reduce the caffeine, a caffeine filter is provided. Furthermore, a coffee receptacle is provided to hold the decaffeinated coffee. A filter chamber is positioned over the coffee receptacle. The caffeine filter is placed in the filter chamber. Brewed coffee is dripped, poured, or otherwise advanced into the filter chamber. At least some of the brewed coffee flows through the caffeine filter and into the coffee receptacle. This reduces the level of caffeine of the filtered coffee entering the coffee receptacle. The system also enables a single source of brewed coffee to produce cups of both regular coffee and decaffeinated coffee, using only one type of regular ground coffee.

Various beverage preparation systems, components, and methods are disclosed. In some embodiments, the system includes a brewer machine and a beverage pod. The brewer machine can include a brew chamber unit, which can receive the beverage pod. The brew chamber unit can be adapted to receive multiple beverage pod types. Some embodiments include a drawer that includes the brew chamber and that moves to present the brew chamber unit to a user. Certain embodiments include locking mechanisms.

A device for extracting a substance to be brewed comprising: an extraction compartment in a first and a second portion, movable relative to the first portion to switch the compartment between a closed position and an open position; a linking device between the first and the second portion, comprising a holder with a first link so configured as to produce a rotation of the holder relative to the first portion, and a second link relative to the second portion, and the device comprises an articulation joint so configured as to successively produce, during a rotational motion of the holder about the first link in a first direction of rotation, a first tilting of the second portion in the first direction, then a second tilting of the second portion in a second direction opposite the first direction.
