System to prepare nitrogen infused beverages

A system for preparing and dispensing a nitrogen infused beverage, comprising:

• a beverage concentrate container;
• a first pump controlling flow of a beverage concentrate through a beverage line from the container to a first flow controlling point and from the first flow controlling point to a nitrogenated beverage liquid mixing point,
• wherein a first back-check valve is optionally present prior to the first flow controlling point or after a flow controlling point needle valve and prior to the nitrogenated beverage liquid mixing point;
• a second pump controlling water flow through a water line from a water supply to a liquid/gas contactor unit and from the contactor unit to a second flow controlling point and from the second flow controlling point to the nitrogenated beverage liquid mixing point wherein a second back-check valve is optionally present prior to the second flow controlling point or after the second flow controlling point and prior to the liquid mixing point;
• a controlled pressurized supply of a gas comprising at least 50% by weight nitrogen attached to the liquid/gas contactor unit;
• the liquid/gas contactor unit;
• a nitrogen infused beverage line from the nitrogenated beverage liquid mixing point to a beverage faucet of a faucet tower;
• wherein the beverage faucet is a faucet having a structure such that the infused beverage in the nitrogen infused beverage line remains under pressure during dispense of the beverage from the faucet.
