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.

FROM GINGER BEER · the ginger heat
Fresh ginger's heat, a phenolic ketone that activates TRPV1 (the same capsaicin receptor) at a fraction of chili-pepper intensity. Dried ginger converts gingerol into shogaol via heat-driven dehydration, which is why dried ginger reads as warmer and sharper than fresh root. Ginger beer, the Moscow Mule, and the Dark 'n' Stormy all lean on it.

Vodka, ginger beer and lime, served in copper. Gingerol activates TRPV1, the same receptor capsaicin hits, delivering perceived heat without capsaicin itself. Carbonation lifts the ginger's aroma.
Three people with unsold inventory reportedly met at the Cock 'n' Bull on Sunset Boulevard: John G. Martin of Heublein (stuck with Smirnoff vodka after acquiring the brand), Jack Morgan, the bar's owner (a surplus of his own ginger beer), and Sophie Berezinski, a Russian immigrant with copper mugs from her father's factory. The combination solved each problem and helped launch vodka in America.
