In one embodiment, a beverage system is provided and includes a beverage dispenser and a funnel removably coupled to the mounting ring. The funnel can be configured to receive a primary fluid and an additive, and the funnel can include a mixing chamber configured to combine the primary fluid and the additive into a combined fluid. The mixing chamber can include a plurality of ribs configured to direct the combined fluid toward a funnel outlet. The funnel can further be configured to receive the primary fluid through a primary outlet of the beverage dispenser, and the primary outlet can be positioned substantially tangential to a curve of the funnel such that a fluid vortex is formed in the mixing chamber. Additionally, the funnel can be configured to receive the additive from at least one secondary outlet of the beverage dispenser.
