Jamaican Mule

Close, but not the same drink. A Dark 'n Stormy is Gosling's Black Seal and ginger beer with the rum floated on top and lime optional. This one is stirred together, takes a straight Jamaican rum, and the 15 ml of lime is structural rather than decoration.

Taste it flat before you commit to a case. Most supermarket ginger beer is sweetened soda with a whisper of extract. Cloudy, fermented styles like Old Jamaica or Bundaberg have real heat, while Fever-Tree is cleaner and gentler. If it's dull on its own, 90 ml will flatten the rum.

No. Copper is a marketing hangover from the 1940s and a highball full of ice does the same job. What matters more is filling the glass properly. A half-empty glass of ice melts fast, and you'll be drinking watered ginger beer by the third sip.

At this volume, yes. Fifteen ml is enough to notice, and bottled lime carries a cooked, faintly bitter note that sits badly against molasses. One lime gives you roughly 30 ml of juice, so budget half a lime per drink and squeeze it to order.

A classic Jamaican Mule calls for 45 ml (1.5 oz) Dark rum, 15 ml (0.5 oz) Fresh lime juice, 90 ml (3 oz) Ginger beer. That single-serve spec scales cleanly — the recipe above converts it to oz and multiplies it for 2–4 drinks.

A standard Jamaican Mule is roughly 12% ABV once mixed (before ice melt softens it further). That makes it about as strong as a glass of wine.

A Jamaican Mule is built directly in the glass over ice — no shaker required. Add the ingredients in order and give it a brief, gentle stir.
