FROM AGED RUM · from oak barrel aging
Bourbon's fingerprint, extracted from the charred American oak the law requires for aging. Same molecule as the vanilla bean's signature, so a well-aged bourbon legitimately tastes like vanilla. Chemistry, not metaphor. Cognac, aged rum, tequila reposado all extract vanillin from oak too. Different barrels, same molecule.

FROM GRAPEFRUIT · citrus peel oil
An orange rind, squeezed, throws a spray that catches the light. That's d-limonene boiling off. It's roughly 95% of orange peel oil by mass, and the molecule that puts the "orange" in orange anything. Used industrially as a green solvent because the chemistry that dissolves citrus oils also dissolves greasy machinery. The expressed-peel garnish on a cocktail is delivering vaporized limonene to the rim of the glass.

FROM LIME · the lemon aroma
Lemon's defining note: technically a mix of two geometric isomers (geranial and neral) that read as the same aroma to the nose. Lemon peel, lemongrass, lemon verbena, and Indian chai all carry it. In cocktails it's what a lemon twist contributes that lemon juice can't: the volatile expressed from the oil glands, not the acid from the pulp.

Three rums, lime, grapefruit, honey and soda. It is named for the Royal Navy's daily ration of rum, water and lime, the 'grog' that kept scurvy at bay through the age of sail. Don the Beachcomber's tiki interpretation adds honey and grapefruit for depth.
Don the Beachcomber's tiki interpretation of the Royal Navy's daily rum-and-lime ration ('grog'). The Navy's actual daily ration was simple: rum cut with water plus a citrus to prevent scurvy. Don's version layered three rums and added grapefruit + honey for tropical complexity. Frank Sinatra is said to have favored the Navy Grog at Don the Beachcomber's, in Hollywood and Palm Springs.
