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.

A method for forming a beverage, comprising: placing a single cartridge, defining a sealed internal space with first and second chambers, into a cartridge chamber of a beverage forming machine, the first chamber containing a carbon dioxide source arranged to emit carbon dioxide gas for use in car
1. A method for forming a beverage, comprising: placing a single cartridge, defining a sealed internal space with first and second chambers, into a cartridge chamber of a beverage forming machine, the first chamber containing a carbon dioxide source arranged to emit carbon dioxide gas for use in carbonating a precursor liquid, and the second chamber containing a beverage medium arranged to be mixed with a carbonated precursor liquid to form a beverage, the carbon dioxide source being in solid form and having adsorbed carbon dioxide, the first and second chambers being separated by an impermeable wall and isolated from each other inside the single cartridge;closing the cartridge chamber to hold the first chamber in a sealed space arranged to receive and hold carbon dioxide released from the first chamber under pressure;providing a fluid to the first chamber in the cartridge chamber to cause the carbon dioxide source to emit carbon dioxide for use in carbonating a precursor liquid, the step of providing a fluid to the first chamber in the cartridge chamber being performed by pumping fluid into the first chamber in the cartridge chamber to control a rate at which carbon dioxide is emitted by the carbon dioxide source;carbonating a precursor liquid by dissolving at least a portion of the carbon dioxide emitted from the carbon dioxide source into the precursor liquid, thus resulting in a carbonated precursor liquid;introducing pressurized gas into the second chamber while the single cartridge is held in the cartridge chamber to move the beverage medium out of the single cartridge; andmixing the carbonated precursor liquid with the beverage medium to produce a beverage. 2. The method of claim 1, wherein the carbon dioxide source is a carbon dioxide-charged molecular sieve. 3. The method of claim 2, wherein the carbon dioxide source is a carbon dioxide-charged zeolite. 4. The method of claim 1, wherein the step of carbonating includes providing carbon dioxide gas to a reservoir that contains precursor liquid. 5. The method of claim 1, wherein the step of carbonating includes providing carbon dioxide from the carbon dioxide source to a gas side of a membrane such that carbon dioxide on the gas side is dissolved in the precursor liquid on a liquid side of the membrane. 6. The method of claim 1, wherein the step of providing a fluid includes piercing the cartridge using the beverage forming machine to provide the fluid to the cartridge. 7. The method of claim 1, wherein the step of providing a fluid to the first chamber includes delivering fluid to the first chamber in multiple sequential volumes to control carbon dioxide gas production by the carbon dioxide source. 8. The method of claim 7, wherein the delivering of fluid to the first chamber comprises controlling an amount of the fluid provided to the first chamber to maintain a pressure of gas produced by the carbon dioxide source to be in a desired range above an ambient pressure. 9. The method of claim 7, wherein the carbon dioxide source includes a charged zeolite, and the delivering of fluid to the first chamber comprises controlling the fluid provided to the first chamber so as to cause the charged zeolite to emit carbon dioxide over a period of at least 30 seconds. 10. The method of claim 1, wherein the first and second chambers have a volume that is less than a volume of carbonated beverage to be formed using the cartridge portions. 11. The method of claim 1, wherein the steps of providing a fluid and carbonating are performed over a period of time less than about 120 seconds to form a carbonated liquid having a volume of between 100-1000 ml and a carbonation level of about 2 to 4 volumes. 12. The method of claim 1, wherein the step of introducing pressurized gas into the second chamber includes piercing the cartridge to form an opening through which the gas is introduced to pressurize the second chamber. 13. The method of claim 1, wherein the step of carbonating comprises: exposing the precursor liquid in a reservoir to carbon dioxide emitted by the carbon dioxide source. 14. The method of claim 13, further comprising cooling the precursor liquid while in the reservoir. 15. The method of claim 1, wherein the step of providing a fluid to the cartridge chamber comprises controlling an amount of carbon dioxide emitted by the carbon dioxide source to control an amount of carbon dioxide dissolved in the precursor liquid. 16. The method of claim 1, wherein the step of providing a fluid to the cartridge chamber includes, delivering a first amount of fluid to the first chamber in the cartridge chamber,stopping delivery of fluid to the first chamber, anddelivering a second amount of fluid to the first chamber in response to a pressure of carbon dioxide emitted by the carbon dioxide source falling below a threshold value. 17. The method of claim 16, wherein the step of stopping delivery comprises stopping delivery of the first amount of fluid to the cartridge chamber in response to pressure of carbon dioxide emitted by the carbon dioxide source exceeding a value. 18. The method of claim 1, wherein the step of providing a fluid to the cartridge chamber includes, delivering fluid to the first chamber in the cartridge chamber to cause the carbon dioxide source to emit carbon dioxide for use in carbonating a precursor liquid,detecting a pressure of carbon dioxide emitted by the carbon dioxide source, andstopping delivery of fluid to the first chamber in the cartridge chamber based on the detected pressure.
