Until 2003 scientists and archaeologists were not quite sure of the origin of bog butter. Scientists working at the University of Bristol discovered that some samples of the "butter" were of adipose/tallow origin while others were of dairy origin.
In Scotland, the practice of burying bog butter dates back to at least the 2nd or 3rd century. Until recently, Ireland's oldest recorded find of bog butter was a carved hanging bowl dating back to the 6th or 7th century AD. On 28 April 2011, there were press reports of a find of approximately 50 kilograms (110 lb) of bog butter in Tullamore, County Offaly, thought to date back about five millennia. Found in a carved wooden vessel 0.3 metres (0.98 ft) in diameter and 0.6 metres (2.0 ft) in height, it was buried at a depth of 2.3 metres (7.5 ft), and still bore a faint smell of dairy.
