Abstract
A machine for brewing coffee or other hot beverages has a container for a supply of liquid, a heater, a hollow filter holder which can receive a relatively large quantity of comminuted coffee beans or another flavoring agent, and a riser which conveys heated liquid to the filter holder. The admitted liquid contacts the confined supply of flavoring agent and can be discharged by way of a sealable opening in the bottom wall of the filter holder. If the machine is to brew a single cupful or a similar relatively small quantity of a hot beverage, the holder receives an insert which can hold a small quantity of flavoring agent and is contacted by hot liquid before the liquid enters the interior of the holder where it can be stored or discharged into a cup or another relatively small vessel. The insert has a bottom wall provided with a recess for one or more small bags of flavoring agent, and the bottom wall of the insert has one or more siphons or other types of outlets for evacuation of a freshly brewed hot beverage from the recess.
