IN THE GLASS

VANILLIN

FROM RYE · from oak barrel aging

Formula
C₈H₈O₃
Mass
152.15 g/mol
IUPAC
4-hydroxy-3-methoxybenzaldehyde

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.

D-LIMONENE

FROM ORANGE PEEL · citrus peel oil

Formula
C₁₀H₁₆
Mass
136.24 g/mol
IUPAC
(4R)-1-methyl-4-prop-1-en-2-ylcyclohexene

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.

CHEMISTRY

Rye in place of bourbon: a spicier grain bill and a drier finish. Vanillin comes from the barrel either way; the swap trades corn sweetness for pepper.
