Carbon dioxide levels in an open-container beverage are measured by transferring a quantity of the beverage to a vessel. A closure is secured onto the vessel to form an enclosed volume containing the beverage. A probe is inserted through the closure to contact the beverage, and a sample is transferred from the vessel to a measurement instrument to determine the carbon dioxide level. The methods allow for significantly greater precision and reliability in measuring carbonation levels of open-container beverages relative to currently available techniques.

Method of measuring carbonation levels in open-container beverages

In at least some embodiments, a carbonated beverage is formed by filling a container with a beverage liquid, adding solid carbon dioxide, sealing the container, and then limiting the development of overpressure within the container. In some embodiments, overpressure within a container may be limited by an adsorber material element. In some embodiments, overpressure within a container may be limited through agitation of a sealed container.
