🥃 Mount Gay XO

Spirit line ✔ Checked: 10.2026 · sources: 4 Updated:

Mount Gay's oldest line: a rum blend aged 5 to 17 years in American whiskey, bourbon and cognac casks; 43% ABV per RumX.

Mount Gay XO is the oldest line in the core range of the Mount Gay brand. The official page calls it round and complex, with a creamy body and notes of salted caramel, baked fig, clove and dark chocolate. According to RumX, its strength is 43% ABV.

It is a blend of molasses rums aged 5 to 17 years. It contains column still and double pot still rum, and matures in ex-American whiskey, bourbon and cognac casks. The Fat Rum Pirate review links the cognac casks to the owner, Rémy Cointreau, and notes that the recipe may shift slightly, as XO is a permanent product. The range of components used to be narrower, 8 to 15 years.

Why this matters to you. XO is the most mature line among Eclipse, Silver and Black Barrel, so it is chosen for slow sipping rather than mixing. The figure 17 in some references is the age of the oldest component, not the age of the whole blend. The WHO reminds us that there is no safe level of alcohol consumption.
