Il Centro Enologico Austriaco in Klosterneuburg ha provato i nostri strumenti per l’enologia

Il Wine Center in Klosterneuburg (vicino a Vienna) , ha provato i nostri due strumenti OIV ufficiali SUPERDEE  e SUPERALCOMAT e questo è  il risultato delle prove.

Abstract – The SUPER DEE (Digital distilling unit mod. Super Dee) device developed from the Italian Company Gibertini is being tested. With the new SUPER DEE device the time requirement for an alcohol and volatile acidity analysis can be drastically reduced compared to the accredit OIV-norm analysis method by destillation. Additionally there is also a hydrostatic scale named SUPER ALCOMAT from the Gibertini company in use for the analysis of available alcohol (Vol.-%). To detect some possible analysis deviances between the Gibertini device and the OIV-norm analysis method by destillation a comparison of both methods will be made. A validation of the Gibertini device will be made as well. Regarding to the reproducibility limits of the Alcohol analysis (set by OIV) the Gibertini device stays within the range. When it comes to the analysis of Volatile Acid, the Gibertini device achieves better results than the reference method. Regarding to the reproducibility limits of the Volatile Acid analysis (set by OIV) the Gibertini device stays as well within the range. The Gibertini device analyzes all over the measuring range as equivalent as the reference method when doing the comparison of the methods for the alcohol analysis and the Volatile Acid analysis. Since the “Limits of Agreement” in the Bland-Altman-plot were only slightly higher than the limits of maximum acceptable differences, the method with Gibertini can be confirmed as suitable to use. In summary, the capability of the Gibertini device can be affirmed.
