Systems, apparatuses, and methods for making a frozen beverage are disclosed. In the systems, a mixing stage mixes water and syrup to form a mixture. An ingredient flow path upstream the mixing stage feeds the water and syrup to the mixing stage. The ingredient flow path includes at least one ingredient sensor and an adjustable liquid flow control device. A mixture flow path receives the mixture downstream the mixing stage and includes a mixture sensor. An electronic control system is in connected communication with the ingredient sensor, mixture sensor, and adjustable flow control device, stores a target value associated with a brix, and is configured to achieve the target value by adjusting liquid flow through the liquid flow control device based on flow detected by the ingredient and mixture sensors. A freezing stage downstream the mixture flow path at least partially freezes the mixture.
