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.
Beverages with high solids content are typically opaque or nearly opaque due to solid materials suspended within the beverage. Examples include tomato juice, orange juice, milk, smoothies, soy milk, and protein drinks. These beverages are best measured using a reflectance instrument.
