The mixing and delivery system comprises a blender and a water supply system for providing the charge of water for mixing with the charge of the particulate drink ingredient, the blender having an impeller for mixing the charges while holding them in the blender and having an outlet for flow of the resultant drink out of the blender and into a cup after mixing has been completed. The charges are held in the blender by the impeller, without a valve. A rinsing system is disclosed for delivering a quantity of water to the mixing and delivery system for rinsing the system of residual drink ingredient.
