IN THE GLASS

α-PINENE

FROM GIN

Formula
C₁₀H₁₆
Mass
136.24 g/mol
IUPAC
2,6,6-trimethylbicyclo[3.1.1]hept-2-ene

The pine note in juniper berries, and the reason gin tastes like a forest. Co-distilled with the spirit during production. Found in actual pine trees, rosemary, basil, and a good London Dry. The "Christmas tree" smell of gin and the smell of a forest floor share a single molecule.

GENTIOPICROSIDE

FROM BENEDICTINE + BITTERS

Formula
C₁₆H₂₀O₉
Mass
356.33 g/mol
IUPAC
(3S,4R)-4-ethenyl-3-[(2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy-4,6-dihydro-3H-pyrano[3,4-c]pyran-8-one

The bitter from gentian root, used across Campari, Aperol, sweet vermouth, Angostura, and most amari. Bitter compounds activate TAS2R taste receptors that evolved to detect plant alkaloids. The same machinery that makes broccoli taste bad to children also makes a Negroni taste like an adult ordered it.

METHYL ANTHRANILATE

FROM PINEAPPLE · the grape candy note

Formula
C₈H₉NO₂
Mass
151.16 g/mol
IUPAC
methyl 2-aminobenzoate

The grape-candy / Welch's-grape-juice aroma. Concord grapes carry it in concentrations no European wine grape (Vitis vinifera) approaches; American Vitis labrusca grapes, native to the northeastern US, hold methyl anthranilate as a signature. The "foxy" note in North American grape juice and artificial grape candy both come from the same molecule. Also used as the standard bird repellent on commercial fruit crops; birds find it intolerable.

CHEMISTRY

Gin, Cherry Heering, Benedictine, orange curaçao, lime, pineapple, grenadine, Angostura and soda. Nine ingredients: tiki complexity applied to a Southeast Asian bar format. The notes are Cherry Heering's benzaldehyde, Benedictine's 27 botanicals, Angostura's bark and alpha-pinene from the gin.

PROVENANCE

Ngiam Tong Boon is credited with inventing the Singapore Sling at the Long Bar of the Raffles Hotel around 1915. In the hotel's telling, it was created for women: the colonial-era social rule was that ladies could only drink fruit juice in public, so Ngiam disguised a serious cocktail beneath the pink fruit-juice color. The original recipe was lost; Raffles Hotel's modern version was reconstructed from Ngiam's nephew's memory in the 1970s. The Long Bar still serves it, with monkey nuts strewn across the floor (deliberately; it's the bar's signature).
