The Institute of Brewing Analysis Committee has organised two collaborative trials for the analysis of alcohol using the ServoChem Automatic Beer Analyser (SCABA). The mean repeatability ( r 95 ) values for the two trials were 0.051% and 0.034% V/V respectively. The value for the second trial could however be judged to be dependent on concentration (m) at 0.008 m % V/V. The Reproducibility ( R 95 ) values of both trials were judged to be dependent on concentration at 0.027 m % V/V and 0.025 m % V/V respectively. The combined data for the two trials gave r 95 = 0.044% V/V and R 95 = 0.026 m % V/V.
