Replicate beer samples were degassed with ASBC method Beer-1D (rotary shaker) and with the Innlab Decarbonyzer. Assessments of alcohol and real extract were made with an Anton Paar Beer Analyzer. Comparisons of results of foam-active and haze-active protein were also made. Real extract and alcohol results were significantly lower (p < 0.001) with the Decarbonyzer than with Beer-1D; this indicates more vigorous removal of CO₂ and other volatile compounds. The results for haze-active and foam-active protein were not significantly different between the two methods.
