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.

CITRAL

FROM LEMON · the lemon aroma

Formula
C₁₀H₁₆O
Mass
152.24 g/mol
IUPAC
(2E)-3,7-dimethylocta-2,6-dienal

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.

CHEMISTRY

Gin, maraschino, crème de violette and lemon. Alpha-pinene from juniper sits under a floral and cherry layer. The violet color is pigment, not flavor-driven. With too much lemon, its citral overpowers the blossom.

PROVENANCE

Published in Ensslin's Recipes for Mixed Drinks. The original spec included crème de violette, which gave the drink its pale sky-blue color and, presumably, its name. The 1930 Savoy Cocktail Book printed the recipe without the violette, and the cocktail's color went gray for decades until Rothman & Winter brought the liqueur back to the US market in 2007.
