Gold Medal Ales are produced monthly in recognition of some of the 'greats' of history.
This month's story :-

Rudolph Diesel, born in Paris in 1858, patented an engine in 1882 that was to bear his name and make him a fortune. It was more efficient than any other method for driving locomotives and ships.
In 1913 he sailed for England for talks with the Admiralty. He disappeared in mid Channel and his body was found 10 days later with no cause of death being apparent.
This led to speculation ranging from suicide to murder, either by wealthy coal owners or the German Government to prevent the Royal Navy re-equipping with diesel engines.
