SwitchExplanation
Convert US fluid ounces of light rum to grams using a density reference of 0.953 g/mL. On that basis, 1 US fluid ounce works out to 28.18 grams for this ingredient.
That is especially useful for cocktail specs, bottle-fill checks, and bar batching where light rum starts as a measured pour but the target is weight. Light Rum is treated here as 40% ABV, so stronger or lower-proof bottles can shift the practical density slightly.

Light Rum density evidence
Light rum is a clear or very lightly colored rum produced from sugarcane byproducts, typically molasses. It is known for its clean, mild profile and is widely used as a base spirit in cocktails where freshness, balance, and mixability are prioritized over heavy barrel influence.
Practical use: Light rum is primarily used as a base spirit in refreshing and citrus-driven cocktails. It is essential in classics such as the Mojito and Daiquiri, and it plays a central role in tropical drinks like the Piña Colada. Its clean structure allows other ingredients—fresh citrus juice, sugar, herbs, and fruit—to remain clearly defined, making it a foundational spirit in both classic and modern mixology.
Composition and sensory context: Light rum presents a clean, lightly sweet profile with subtle notes of sugarcane, vanilla, and faint tropical fruit. It is generally low in oak influence and perceived heaviness, offering a smooth, neutral backbone that integrates easily with citrus, mint, and fruit-forward ingredients. Compared to aged or dark rums, its character is restrained, emphasizing clarity and drinkability rather than depth from maturation.
Light 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 Light Rum is Añejo Rum at 0.953 g/mL: an absolute difference of 0 g/mL (0.0% relative to Light 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.
