As the ingenious Dr. Frappel points out in this ground-breaking publication, bottled beer may be used to calibrate a CO2 analyser in the absence of a calibration gas standard. This is achieved by measuring the dilution of O2 when gas collected in the headspace of the bottle is diluted with atmospheric air. The method is simple and means that you no longer need to carry a calibration tank into the field, but can schlep a Two-Four of your favourite brew instead. Brilliant!
