Does every urban myth contain a kernel of truth? Rumours have been rife for years that a network of tunnels stacked with barrels of whiskey worth millions of pounds exist under Holywood in County Down. Local journalist Jordan Dunbar is on a mission to distil the truth of it all with the promise of commandeering some precious liquid gold.

In this four-part escapade, Jordan learns about the celebrated Dunville family, whose wealth was built on their whiskey brand that became globally famous during the 19th century. It allowed the family to indulge in acts of opulence and eccentricity well into the 20th century. So, might that just include stacking tunnels full of whiskey barrels that have now been left unopened for decades? In a caper that features hot air balloons, private zoos and whiskey tours, Jordan discovers how the fate of the Dunvilles mirrored the fate of the Irish whiskey industry itself. Historians Jason Burke and Robin Masefield give pause for thought on why the rumours of the whiskey in tunnels might just have to be taken seriously after all. But as Jordan increasingly gets into the ‘spirit’ of it all, can he get any closer to the elusive ‘uisce beatha?’

In this episode, Jordan goes to the site of what was Redburn House built by Robert Grimshaw Dunville in the hills above Holywood to a design by celebrated architect of the day, Charles Lanyon. Here, the family enjoyed a life of incredible luxury with more than 60 rooms, a stable full of horses and an ornate garden. Servants catered for every need and now the Dunvilles have truly arrived.
