SwitchExplanation
Convert US cups of dark rum to grams using a density reference of 0.953 g/mL. With the US cup fixed at 236.588 mL, that gives 225.47 grams per cup for this ingredient.
That is especially useful for cocktail specs, batching sheets, and inventory work where dark rum starts from weight but service still uses poured measures. Dark Rum is treated here as 40% ABV, so stronger or lower-proof bottles can shift the practical density slightly.

Dark Rum density evidence
Dark rum is a style of rum typically produced from molasses and aged in oak barrels, or colored and enriched through extended aging and blending techniques. It is characterized by deeper color, fuller body, and more pronounced caramelized and oak-driven flavors compared to light or white rum styles.
Practical use: Dark rum is commonly used as a base spirit in richness-driven and spirit-forward mixed drinks where body, warmth, and depth are required. It is foundational in tropical and tiki-style builds, often used alone or in blends to provide density and caramelized backbone. It also serves as the classic partner for ginger-based mixers in long drinks, where its molasses depth anchors spice and carbonation. Beyond cocktails, dark rum is widely used in baking, sauces, and desserts to add richness and aromatic complexity.
Composition and sensory context: Dark rum presents a rich and robust profile built around caramelized sugar, molasses, and toasted oak notes. Secondary aromas often include dried fruit such as raisin and prune, along with baking spices like cinnamon and clove. Sweetness is perceived as high due to molasses-derived aromatics rather than added sugar, texture is round and weighty, and the finish is warm and lingering with subtle toasty and lightly smoky nuances.
Dark Rum uses 0.953 g/mL in this dataset, which is 4.7% lighter by volume than the 1 g/mL water reference. Evidence status: medium-confidence. Source basis: Approx density for ~40% ABV ethanol-water at room temp (used across base spirits).
Among the 15 reviewed records labeled Spirits, the nearest density to Dark Rum is Añejo Rum at 0.953 g/mL: an absolute difference of 0 g/mL (0.0% relative to Dark Rum). The observed range in this labeled group is Añejo Rum at 0.953 g/mL to Whiskey at 0.953 g/mL. This is a numerical comparison, not a claim that the liquids are interchangeable.
Brand formulation, alcohol or sugar concentration, carbonation, and serving temperature can change the weight of a measured volume. Use this value as a documented reference rather than a producer specification.
