Claim:
1. A device for carbonating a liquid, the device comprising: a carbonation head, pressure transducer and processor module; wherein the carbonation head is connectable to a bottle whose liquid contents are to be carbonated and has a first through passageway that, when connected, distributes pressurised carbon dioxide to an interior of the bottle; and a second passageway that communicates a pressure within the bottle to the pressure transducer; and the processor module is coupled to the pressure transducer to receive a signal indicative of the pressure within the bottle; wherein the processor module, prior to commencing carbonation, causes delivery of a single short predetermined pulse of a gas into the bottle, and the pressure transducer subsequently measures a resultant pressure within the bottle; the processor module being further adapted to monitor the resultant pressure within the bottle and to compare the measured pressure to a predetermined safe pressure range defined by a lower first pressure value and a upper second pressure value for confirming a safe volume of liquid in the bottle; such that, if the measured pressure is within the safe pressure range, the processor can cause the device to commence carbonation of the liquid.
