Alcohol determination of beverages containing extract…

…done quickly and safely with the Gibertini SUPER DEE !

Distillative methods are still THE standard when it comes to highly accurate, but also legally secure determination of the alcohol content of beverages containing extract. The OIV and EBC distillation method are mentioned here as examples. NIR and other methods must stand comparison with the standard method. However, distillation methods are also considered to be complicated and time-consuming. The electrode-based SUPER DEE sample distillation can help here!

Workflow: Measure 100 ml or 200 ml sample into the calibrated sample flask; medium at 20 °C. Media containing CO2 such as beer, sparkling wine etc. should be degassed. Input of the sample into the distillation vessel, rinsing of the sample flask with a few ml of distilled water, addition of the rinsing water. Depending on the type of media, additive of a few ml of defoamer, increased conductivity or milk of lime (for acid binding). Hang the sample flask in the suspension provided for this purpose, because it also serves as a distillate collecting flask. Pull down the Plexiglas protective screen, the distillation is now started by push of a button. The distillation stops automatically when 2/3 of the sample volume has been distilled off. This prevents “burn-in”. The automatic shutdown is realized with the help of a weighing cell, the distillation runs automatically and therefore does not need to be supervised. Fill up the distillate with distilled water again to 100 ml or 200 ml.

A perfect sample distillate, also in terms of temperature, is ready!

Draining the sample residue, cleaning the distillation chamber is done quickly with the help of the sprinkler gun … the apparatus is now ready for the next distillation again.

The alcohol determination can now be carried out with an officially calibrated alcohol spindle (a very inexpensive but also legally secure measurement!), or with electronic density meters, e.g. the DENSIALCOMAT Gibertini MIA2020.

Fatty samples such as cream liqueurs can also be measured in this way. Cloudy samples such as mash do not have to be filtered – as it is necessary with NIR. Total time required for a determination: only approx. 3 – 5 minutes! Investment costs (if there is a thermostating bath): Around EUR 8.500,–. The costs for consumables per distillation are in the cent range. System accessories: Gibertini THERMOSTAT, with it you can bring up to 5 whole bottles to 20 °C in a short time. Ultrasonic bath for degassing the sample: POLSONIC.
