A beverage dispensing machine for dispensing a mixed beverage has a first inlet configured to receive a concentrate; a second inlet configured to receive a base fluid; a gas inlet configured to receive a gas; a gas injection device configured to pulsate the gas into the concentrate such that the gas agitates the concentrate and is injected into the concentrate to form a gas-injected concentrate; and a dispensing valve configured to dispense the base fluid and the gas-injected concentrate.

A system and method to supply nitrogen gas is provided. Ambient air is compressed and stored in a storage receiver and then nitrogen is separated from the compressed air in a nitrogen membrane separation unit. The separated nitrogen is stored in a nitrogen storage tank under pressure and released through a pressure control valve. The system is confined to a small footprint and is useful as a nitrogen source where conventional compressed nitrogen tanks are a safety or space issue. Systems to prepare nitrogen infused beverages are also provided.

A system and method to prepare and dispense a N.sub.2 or N.sub.2/CO.sub.2 gas infused chilled beverage is provided. The beverage may be any non-carbonated liquid and in one embodiment the beverage is coffee. The dispensed N.sub.2 or N.sub.2/CO.sub.2 gas infused chilled coffee has a unique appearance and enhanced flavor and aroma. The system may be provided as a self-contained unit.
