Fifty Pounds cask at the Back takes us back to the nineteenth century, a time when gin was transported in oak barrels. Some of these barrels had previously contained Sherry and were re-used to transport the gin between various cities and warehouses.
Cask at the back refers to those barrels which were stored at the back of the warehouse and were usually there for longer than those at the front since access was more difficult. The gin they contained thus developed a deeper colour and a slightly different character, above all in those barrels which had contained Sherry.
