Dark rum is a rum defined by color, deep brown to near-black, which comes from long aging in charred barrels, added caramel, or often both.
Another dark rum
Takes the same amount, though brands vary widely.
Works measure for measure, for a lighter-bodied drink.
Blackstrap rum
Add it a barspoon at a time to a lighter rum to restore the weight. Swapped one for one, it takes over the drink.
Flavored with spices and often sweetened, so any syrup can come down.
Dark overproof rum
Much stronger: use half to two-thirds of the measure, depending on its strength.
"dark rum = well-aged / better"
The color is often caramel coloring rather than barrel time, so "dark" means neither "aged" nor "better."
