The IBULyzer is one of the finest examples of how instrument and tasting panel can work together with the shared sensory goal of measuring beer bitterness.
Automate IBU Measurement with an IBULyzer
Free up brewery lab time with automated beer bitterness measurement that is affordable, simple enough for anyone to use, processes samples in just 13 minutes, allows you to queue up to 8 samples at one time and provides the same accuracy as manual methods, with added consistency. A cost effective complement to your internal quality control procedures allowing to brew with consistently tight control over the IBU/EBU values.
As a cost effective analytical solution, IBULyzers are in daily use at-line with both in-process and finished product samples at plants around the world with the backing some of the worlds largest beer brand owners.
1. Present a degassed sample to the IBULyzer 2. Absorbance of pure iso-octane is measured 3. Sample is acidified and iso-octane is added in 1:2 ration 4. Extraction is promoted by forced aeration 5. Transfer for absorbance measurement at 275nm 6. Calculation of IBU and reporting of results 7. Cleaning cycle prevents cross-contamination
Initially trialed with one of the worlds largest beer brand owners, the performance of the IBULyzer results confirmed calibration with expected manual values. Now rolled out globally, the IBULyzer continues to impress.
Several samples with corresponding lab data were supplied by the brewing company enabling us to compare results with the reference lab method. In total 10 different beers, ranging from 8.8 up to 27.8 IBU, were used to assess precision within a single run (repeatability). Results were in fine agreement with the expected values at a RSD (relative standard deviation) of less than 2.2%. Taking into account the relatively large measuring range of the sample set this was indicative of the analyzer’s potential for automated bitterness tests, yet one which does not require special analytical skills. As expected, the test highlighted the importance of careful calibration by means of beers with known reference values, key to obtaining reliable results.
