Abstract: Method and apparatus for forming both carafe quantities and smaller (e.g., cup) quantities of a beverage using a cartridge-based beverage machine. A beverage forming machine accommodates cartridges having different sizes and/or shapes, including different rim sizes/shapes. The outlet used for receiving a beverage from a standard cartridge differs from the outlet used for receiving the beverage from a carafe cartridge inserted in a same cartridge holder. Beverage may exit the cartridge in an upward direction in some embodiments.

Abstract: Systems, methods and cartridges for carbonating a precursor liquid, such as water, to form a beverage. A carbon dioxide source can be provided in a cartridge which is used to generate carbon dioxide gas that is dissolved into the precursor liquid. A beverage medium, such as a powdered drink mix or liquid syrup, may be provided in the same, or a separate cartridge as the carbon dioxide source and mixed with the precursor liquid to form a beverage. The use of one or more cartridges for the carbon dioxide source and/or beverage medium may make for an easy to use and mess-free system for making carbonated beverages, e.g., in the consumer's home.
