El Dorado Mourant Cask Strength Single Still Port Rum 2009
El Dorado Port Mourant Cask Strength Single Still Rum 2009 is a 113.4-proof (56.7% ABV), 750mL vintage Guyanese rum distilled in 2009 on the Port Mourant double wooden pot still — a still built in 1732 from greenheart wood and the only double wooden pot still in use in the world — then aged 12 years in oak at the Diamond Distillery and bottled at cask strength. "Port" is the name of the historic Port Mourant estate, not a port-wine finish: the rum rests in oak, uncut and unblended. It is available to order online at Del Mesa Liquor, San Diego, CA.

The Still That Made Navy Rum
The Port Mourant still began life in 1732 on the Port Mourant sugar estate, survived the closure of Uitvlugt, and was moved to Diamond in 2000 — nearly three centuries of continuous service in greenheart wood. Its double-pot design yields the famously heavy PM marque, the backbone of the rum once issued to the British Navy and, today, of El Dorado's own cask-aged blends. The 2009 vintage spent 12 years in tropical oak before Demerara Distillers bottled it at full cask strength, uncut and unblended. Collectors of fine rum rank Port Mourant among the great historic stills on earth.
Tasting Notes
Deep amber in the glass with aromas of blackstrap molasses, walnut, and pipe tobacco over charred oak. The palate is massive and chewy — dark chocolate, espresso, allspice, and dried cherry — finishing long with leather, clove, and a whisper of smoke. Water tames the heat and reveals fruitcake and Demerara sugar.
How to Enjoy
Sip neat or with a teaspoon of water in a tulip glass. At 113.4 proof it is built for slow contemplation, but a small pour transforms a rum Manhattan. Pair with aged Gouda or dark chocolate.
