Abstract: A post-mix beverage dispenser includes a dispenser head, a diffuser, and a spout. The bottom of the dispenser head includes an outer wall and an inner wall that defines a channel therebetween which allows for the spout to be coupled thereto. The dispenser head includes a dispenser base formed with the inner wall and defines a diluent port and a concentrate port where the concentrate port is centrally positioned. The diffuser includes a cylindrical wall having a base extend inwardly from wall and which defines a channel within the middle of the base. The channel is aligned with the concentrate port and a portion of the base is aligned with the diluent port. The diffuser is designed to dispense agitated, whipped, foamed or frothed beverages by allowing the diluent to exit the diluent port and hit the base, thereby scattering the diluent into the concentrate stream at a high velocity.
