From carbonated soft drinks, fruit / vegetable juices, and milk to coffee, tea, hot chocolate, as well as spirits - beverages can be opaque, translucent or transparent, and will require different instrumentation and techniques for successful colour measurement.

Opaque Liquids usually have a high solids content, are impenetrable by light, and are usually characterized by a high Brix value. These type samples are best measured using Directional 45/0° reflectance instrumentation. This is the geometry that most closely matches how the human eye sees colour.

Translucent Liquids possess a medium level of solids content, along with a lower Brix value and allow light to pass through, but only diffusely, so that objects on the other side cannot be clearly distinguished. Both reflective and transmittance measurement modes may work well depending on the translucency of the sample.

Transparent Liquids  have a very low, or zero, solids content and allow light to pass through with little or no interruption or distortion so that objects on the other side can be clearly seen. These liquids can only be measured using transmission instrumentation.

- Transparent Beverage Colour Measurement

Transparent beverages include water, apple juice, lemonade, soft drinks, coffee and tea, alcoholic beverages and energy drinks. These beverages are best measured using a transmittance instrument.
