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

The 7th August 1947 saw the raft Kon-Tiki grounded on a Tuamoto island reef. The primitive craft had been constructed, mainly of Balsa Wood, to demonstrate Thor Heyerdahl's theory that ancient civilisations had made long sea voyages using only sea currents and the wind.

Thor and his companions sailed 4300 miles in 101 days across the Pacific, from South America to the Polynesian Islands.

Fittingly Thor, a Norwegian Ethnographer and adventurer was a Master Brewer's son, obviously reaching parts that other Ethnographers couldn't reach.
