Spiced rum is rum infused or blended with warming spices like vanilla, cinnamon, clove, and nutmeg, usually with added caramel or sugar.
Dark or gold rum with a pinch of cinnamon and clove and a little syrup gets close, and the syrup is the part people forget. Most spiced rums carry added sugar and caramel, so a plain rum in their place leaves the drink drier and thinner than the recipe expected. Add the syrup half a barspoon at a time and taste. A spiced rum from another producer swaps one for one, and they differ more than the category suggests.
Dark rum
Aged rum with no spice or sugar added, or very little. It gives the same color and none of the vanilla-and-clove sweetness that defines the spiced style.
Overproof and navy rums
Stronger and drier, made for a different job. Using one where a spiced rum was named makes the drink both hotter and less sweet.
