Innovative Ways to Account for Sugars When Measuring Alcohol in Liqueurs
A well-defined alcohol content is an obligatory parameter in quality control for the production of alcoholic beverages. Since many spirits are binary solutions, alcohol concentration is determined through density measurement. However, with liqueurs, more extract is present, and simple density measurement for the finished product becomes less reliable. The liqueur’s sugars need to be accounted for in the ternary solution, or else the liqueur needs to be distilled back to a two-part solution before density measurment. Since sugars like sucrose are optically active, the liqueur’s optical rotation can be measured to determine sugar concentration, allowing alcohol concentration determination without distillation. With this presentation, we will show how optical rotation measurements, combined with density and NIR measurements, can save time in quality control of liqueurs, while providing accuracy comparable to density measurement after distillation.
