Measuring device for the quick determination of the alcohol content of Wine and wine-like beverages, It consists of a tube open at both ends, which is provided with a scale. The mode of operation is based on the phenomenon of the reduction of the surface tension of the water by alcohol, as well as the capillary effect (rising of liquids in narrow glass tubes against the gravitational force upwards). The higher the alcohol content (and thus lower surface tension), the less an alcohol-water mixture is held in the capillary against gravity. The result is in volume displayed, the measuring accuracy is around 0.5% at a temperature of 20 ° Celsius. The measuring range only extends to 25%, which is why the vinometer for distillates is not suitable. A high content of residual sugar in wine affects the accuracy of the measurement. For other measurement methods for wine ingredients see under analytical testing,
