| Pre-batch | 7 oz mixed with ice, 0.8 oz of it pure alcohol |
|---|---|
| Melt | Built in the glass: +5 % of the pre-batch, +0.35 oz of water |
| Served | 7 + 0.35 = 7.35 oz in the glass |
| Strength | 0.8 ÷ 7.35 = 10.9 % ABV as served |
| Ethanol | 0.8 oz × 29.57 ml × 0.789 g/ml = 19 g · about 131 kcal from the alcohol alone |
FROM WHISKEY · 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 COLA · the alertness molecule
A purine alkaloid that blocks adenosine receptors in the brain, so the tiredness signal never lands. Coffee, tea, cocoa, mate, guarana, kola: all unrelated plants, all evolved caffeine independently as an insecticide. Humans inherited a tolerance for what bugs can't handle.
Whiskey and cola. Oak-derived vanillin and char congeners meet cola's caramel and phosphoric acid. The cola's sugar softens the ethanol's burn, but the ethanol load is unchanged.
Cold cola, straight from the fridge. Henry's Law: kH rises as a liquid warms, so opened warm cola is further over its CO₂ limit and sheds gas fast as it pours, before the drink is built, and the fizz collapses in the glass. A cold pour holds the carbonation through the whiskey mix.
The Rum and Coke (Cuba Libre) was first mixed in Havana around 1900, by the usual account when American soldiers paired the newly arrived Coca-Cola with the local Bacardí. The whiskey variant followed naturally through the 1940s and 50s as American whiskey production rebuilt after Prohibition. Jack Daniel's marketing in the 1970s cemented the pairing as Jack & Coke specifically.
