Beverage infusion apparatus and method for infusing gas into a beverage

A beverage infusion apparatus comprising:

• (a) a mixer for mixing a beverage concentrate and water to form a diluted concentrate, wherein the water is provided at a water pressure during operation sufficient to flow through the beverage infusion apparatus;
• (b) an infusion module for infusing a nitrogen containing gas into the diluted concentrate to form a gas infused beverage, wherein:
• (i) the infusion module comprises a gas draw venturi device for drawing the nitrogen containing gas into the diluted concentrate as a result of flow of the diluted concentrate through the gas draw venturi device to form the gas infused beverage;
• (ii) the gas draw venturi comprises a non-gas infused beverage inlet, a gas infused beverage outlet, and a restriction between the non-gas infused beverage inlet and the gas infused beverage outlet;
• and
• (iii) the gas draw venturi is constructed to draw the nitrogen containing gas at atmospheric pressure into the non-gas infused beverage;
• and
• (c) a dispensing valve for dispensing the gas infused beverage and constructed to move between an open position and a closed position, wherein:
• (i) the open position permits dispensing of the gas infused beverage from the beverage infusion apparatus;
• (ii) the closed position prevents dispensing of the gas infused beverage from the beverage infusion apparatus;
• and
• (iii) the dispensing valve is constructed to move between the open position and the closed position by a user of the beverage infusion apparatus, wherein the gas draw ventruri is upstream of the dispensing valve.
