Method of preparing a beverage with mixing chamber

A method for forming a beverage, comprising:

• providing an alcoholic beverage medium to a beverage medium chamber of a mixing chamber;
• causing flow of a precursor liquid from a precursor liquid inlet of the mixing chamber to a dispense outlet of the mixing chamber;
• causing flow of alcoholic beverage medium under pressure from the beverage medium chamber to the dispense outlet via a chamber outlet while preventing flow of precursor liquid into the beverage medium chamber;
• dispensing beverage medium and precursor liquid from the dispense outlet;
• reducing a pressure in the beverage medium chamber to permit flow of precursor liquid into the beverage medium chamber via the chamber inlet;
• and
• permitting precursor liquid that flows into the beverage medium chamber via the chamber inlet to exit the beverage medium chamber via the chamber outlet;
• wherein the precursor liquid inlet and the dispense outlet are connected by a 90 degree elbow, the chamber inlet is positioned at an upstream end of the 90 degree elbow, and the chamber outlet is positioned at a downstream end of the 90 degree elbow.
