The El Dorado Single Still Port Mourant Rum is produced from the Double Wooden Pot Still which is the only one of its kind in use today. Constructed in 1732 on the Port Mourant Estate, this still was later moved to the Uitvlugt Estate and then to Diamond Estate in 2000.

Since then, the Double Wooden Pot Still has been producing small batches of this El Dorado Heritage Rum. This rum was laid down in oak barrels for 12 years.
