ABV TESTING OF ALCOHOLIC BEVERAGES

Watching the Masters Golf Tournament, Superbowl, World Series or Monster Truck Show with a pint of beer or shot of liquor ? If so, you might be wondering about Alcohol Content and how many pints, glasses or shots you can have before driving home.

Therefore, it’s important that breweries, wineries and distillers of these products accurately test their products to determine the alcohol content. In their quality control and labeling testing, companies use Alcohol by volume (ABV) Testing. ABV Testing is a measure of the alcohol content in a specific volume of a beverage. This test determines how many milliliters of ethanol are present in 100 milliliters of a liquid. ABV Testing is a worldwide standard for measuring alcohol content in an alcoholic beverage. Two popular techniques for measuring alcohol content include distillation and gas chromatography.

Distillation

During the distillation process, alcohol first has to be separated from the liquid using specialized equipment. A hydrometer determines the specific gravity of the distilled alcohol, which is calibrated directly in % vol at 20 °C. If the temperature varies, corrections are made since the volume of the liquid changes with temperature. Distillation is a complex and time consuming process and accuracy is difficult as numerous errors can occur.

Gas Chromatography

Another technique is the gas chromatography method, the most accurate method for determining alcohol content. This method works by analyzing a mixture of organic compounds and then running them through a chromatograph device. The temperature of the device is important and must be above boiling in order to convert the liquid into gas. The gas then passes through filters that identify the different compounds, ultimately determining the alcohol content. Gas chromatography has the added benefit of providing additional information about the wine, beer or liquor product.
