Alcohol determination in wines

Made from grapes, wine is a widely consumed alcoholic beverage. In most jurisdictions worldwide it is a legal requirement to quantify the alcohol content for labelling and taxation purposes. An accurate and reliable method for the determination of the alcohol content in five different wine samples with varied alcohol concentrations in comparison to a classical distillation setup as a reference method is hereby introduced in co-operation with Versuchs-und Lehranstalt für Brauerei (VLB), Berlin. A close compliance of the steam distillation setup of EasyDist with the 1:8 distillation protocol to EEC2676/1990 (wine) and OIV-MA-AS312-01A (wine) is shown. The wine samples are distilled using the distillation unit EasyDist with a glass splash protector. The alcohol content was determined after the distillation by direct injections in a digital density meter.
