The simple method for head space air volume measurement was developed, using electrochemical Oxymeter with covered electrode connected to piercing apparatus. After crown cork piercing, the gas of bottle headspace passes Oxymeter and blows free into atmosphere, from overpressure values measured in bottle neck and Oxymeter reading will be air volume in head space of bottle calculated. This described method is quick and accurate. At simultaneous measurements of oxygen volume in head space and in beer there can be used two sensors connected to one Oxymeter.To estimate the beer predisposition to gushing, crown cork of shaked out and calmed bottled beer had been pierced, after measurement chamber closing the CO2 overpressure released and kinetic of supplementary overpressure accrual was measured.The simple method for head space air volume measurement was developed, using electrochemical Oxymeter with covered electrode connected to piercing apparatus.
