Kirkland Signature XO Aged Rum is a premium aged rum sourced from Guatemala and finished in cognac casks, offering a sophisticated sipping experience at an exceptional value. The XO designation ("Extra Old") indicates an extended aging process that produces a smooth, complex spirit with the depth and refinement typically associated with much higher-priced rums.

Distilled in Guatemala, a country renowned for producing some of the world's finest aged rums, this expression undergoes finishing in cognac casks that impart distinctive notes of dried fruit, vanilla, and subtle oak. The cognac cask finishing adds a layer of elegance and sweetness uncommon in standard aged rums, making it an excellent choice for both sipping neat and crafting elevated cocktails such as daiquiris or old-fashioneds.

Rum enthusiasts have noted this expression shares similarities with notable Guatemalan rums in the $40–50 range, making it a compelling value at its Costco price point. Bottled at 750ml, this is a versatile addition to any home bar.
