OG exemplary drawing
 
1. An additive cartridge for adding additive to base liquid in response to the base liquid flowing through the additive cartridge from a base liquid container, the additive cartridge comprising:
a base for securing the additive cartridge to the base liquid container;
a mixing nozzle comprising:
a main body portion;
a mixing nozzle stem extending from the main body portion, the mixing nozzle stem including an opening to an interior space defined by a mixing nozzle metering surface on an interior of the mixing nozzle stem;
a reservoir assembly interface extending from the main body portion and adapted to support a reservoir assembly;
an additive passage extending through the mixing nozzle stem and defining an additive flow path from the reservoir assembly interface to the mixing nozzle metering surface; and
at least one base liquid port extending through the mixing nozzle main body portion adjacent to the mixing nozzle stem;
a metering component extending through the opening and within the interior space of the mixing nozzle stem and having a metering component metering surface shaped complementarily to the mixing nozzle metering surface; and
an additive adjustment actuator cooperating with the metering component such that movement of the additive adjustment actuator causes movement of the metering component metering surface relative to the mixing nozzle metering surface.
