Abstract
A beverage container for a nitrogenated beverage comprises at least two restricted outlet apertures (11, 12) configured to, when pouring therefrom into a secondary vessel, form jets of beverage that impinge downstream. Impingement initiates nucleation of dissolved nitrogen gas in the beverage and, as such, when poured into the vessel a creamy head of fine nitrogen/mixed gas bubbles can be formed. The restricted outlet apertures can be formed in a plate (10) over an openable mouth of the beverage container, or directly upon the container. Preferably a vent (14) or some other feature is included to increase the velocity of the jets.
Claims19
A single-serve beverage container of nitrogenated beverage, the container comprising an end having at least two jet-forming outlet apertures and a vent or other feature to increase beverage velocity through the at least two jet-forming outlet apertures, the container being configured to, when pouring therefrom, form jets of beverage that impinge downstream for initiating nucleation of dissolved gas in the beverage.
A method of pouring a nitrogenated beverage from a single-serve beverage container to form a creamy head on the beverage in a secondary vessel, wherein the container includes at least two jet-forming outlets therefrom, the method including the steps of:
- opening the beverage container so that flow of beverage through the at least two outlets is possible;
- tilting the beverage container over an opening of the secondary vessel so as to pour beverage through the at least two apertures and form at least two corresponding jets that converge downstream of the outlets and initiate nucleation of dissolved gas, toward the secondary vessel;
- wherein a velocity of the jets sufficient to initiate nucleation is achieved by a vent opened through a wall of the beverage container and/or causing deformation of a wall of the container.
