The Drink That Changed Everything
The Moscow Mule wasn't just a cocktail — it was a marketing masterstroke. In 1941, John G. Martin (who had the American rights to Smirnoff vodka), Jack Morgan (who couldn't shift his Cock 'n' Bull ginger beer), and Sophie Berezinski (who had 2,000 copper mugs she couldn't sell) walked into a bar. What emerged was the drink that single-handedly launched vodka's dominance in the American market.
Why the Copper Mug?
The copper mug isn't just theatre — though it is that. Copper conducts cold exceptionally well, so the mug frosts instantly and keeps your drink colder, longer. The metal also reacts subtly with the lime juice and ginger, adding a faint metallic brightness that you won't get from glass. If you don't have a copper mug, a highball glass works — but you'll know the difference.
The Ginger Beer Question
This is where most Moscow Mules fail. Ginger beer, not ginger ale. You want something with real ginger heat — Fever-Tree, Bundaberg, or Q Mixers all deliver genuine spice. Sweet, flat ginger ale produces a sweet, flat cocktail. The burn of proper ginger beer against cold vodka and sharp lime is the entire point of this drink.
Variations Worth Trying
- Kentucky Mule: Swap vodka for bourbon — warmer, richer, excellent in autumn
- Mexican Mule: Tequila instead of vodka, with a salted rim
- Dark 'n' Stormy: Dark rum and ginger beer — the Bermuda cousin
