Determination of alcohol in dealcoholized wine
Dealcoholized wine must be checked for residual alcohol to meet legal limits and ensure accurate labeling while still having a palatable taste. The improved wine model of the Alcolyzer alcohol measurement module enables precise detection of very small alcohol amounts in dealcoholized wine, supporting reliable quality control.
Non-alcoholic or “alcohol-free” wines are one of the fastest-growing segments of the beverage market with an estimated continuous annual growth of 7–10 %, with projections approaching USD 4 billion by 2030.
Most products either start as conventional wine and are then dealcoholized, or they are blended beverages based on grape must, juice and flavors. Although described as “alcohol-free,” these wines typically contain small amounts of ethanol. The ethanol residue acts as stabilizer, aroma carrier and enhances the smell and mouthfeel, often making it desirable to dealcoholize as close as possible to the lower legal limit.
Accurate quantification of residual ethanol is essential for regulatory compliance, consumer protection, and process control. As regulatory thresholds often fall below 0.5 %v/v analytical methods used must be capable of measuring ethanol with high sensitivity, accuracy, and repeatability.
This application note presents an analytical approach suitable for determining ethanol in alcohol-free and dealcoholized wines with an accuracy of ≤ ± 0.15 %v/v, depending on the glycerol content.
