A method of dispensing an alternative post-mixed beverage from a post-mix beverage dispensing head having a first and primary beverage, comprising the steps of:

• (a) opening a normally closed water valve in a water line from a water source to a dispensing nozzle and opening a normally closed primary syrup valve in a primary syrup line from a primary syrup source to the dispensing nozzle;
• (b) closing the primary syrup line at a location upstream of a location of the opened primary syrup valve so that water will flow but primary syrup cannot flow;
• (c) concurrently opening a normally closed alternative syrup valve in a secondary syrup line leading from an alternative syrup source to the dispensing nozzle, so that an alternative syrup rather then the primary syrup will flow to the nozzle;
• and in which
• (d) said water valve, primary syrup valve and alternative syrup valve are all simultaneously opened, and in which said primary syrup line is closed prior to said simultaneous openings.

A method of firstly dispensing an alternative post-mixed beverage and secondly a primary post-mixed beverage from a single post-mix beverage dispensing head having a first and primary beverage, comprising the steps of:

• (a) opening a normally closed water valve in a water line from a water source to a dispensing nozzle and opening a normally closed primary syrup valve in a primary syrup line from a primary syrup source to the dispensing nozzle;
• (b) closing the primary syrup line at a location upstream of a location of the opened primary syrup valve so that water will flow but primary syrup cannot flow;
• (c) concurrently opening a normally closed alternative syrup valve in a secondary syrup line leading from an alternative syrup source to a dispensing nozzle, so that an alternative syrup rather than the primary syrup will flow to the nozzle, and dispensing an alternative beverage;
• (d) subsequently closing the water valve and the primary syrup valve and the alternative syrup valve so that the alternative syrup and alternative beverage cannot further flow;
• (e) opening the primary syrup line at said location upstream of the primary syrup valve;
• and
• (f) reopening the normally closed water valve and the normally closed primary syrup valve simultaneously with the upstream opening of the primary syrup line, and dispensing primary beverage from the head.
