Mix Considerations – General Freezing characteristics are affected by the amount of sweeteners and solids in the mix, called BRIX. BRIX can be measured with an instrument called a refractometer.

Mixes with too high a brix level will take longer to freezer down and will yield a soft, wet, frozen product. Mixes with too low a brix level wi
