Method for monitoring beer kegs

A method for monitoring the use of beer kegs, and the status of beer contained therein, for a brewery having a source of beer, wherein the brewery in operation fills the kegs with beer and communicates directly with the kegs, the method comprising the steps of:

• providing a sensor system and attaching it to a beer keg;
• providing a two-way information communication link over a cellular network directly connecting the brewery and the sensor system on the keg concerning the status of the keg and the beer therein, including providing information to the brewery from the sensor system that the keg has arrived at the brewery for filling and confirming to the sensor system on the keg from the brewery that the arrived keg is ready to be filled with beer by the brewery following cleaning thereof by the brewery;
• filling the beer keg which has been cleaned and is otherwise ready to be filled with beer by the brewery;
• providing information to the sensor system on the keg by the brewery, including the date on which the keg has been filled with beer by the brewery;
• transporting the filled keg or alternatively, temporarily storing and transporting the filled keg thereafter, by the brewery to a destination;
• acquiring information by the sensor system concerning the temperature of the beer in the keg by a temperature sensor in the sensor system when movement of the filled keg occurs and providing an alert to the brewery over the cellular network when the temperature of the beer is out of a standard temperature range;
• acquiring location information of each keg individually by a location sensor in the sensor system as the keg moves from the brewery to its destination and providing the location information of the keg to the brewery;
• and
• wherein all information acquired by the sensor system is provided directly to the brewery over the cellular communication link and all information concerning the kegs by the brewery to the sensor system is provided directly over the cellular communication link.
