Question: what is the main difference between the jamaican mule and dark & stormy cocktail?
Answer: A Dark 'n' Stormy is a highball cocktail made with dark rum (the "dark") and ginger beer (the "stormy") served over ice and garnished with a slice of lime. Lime juice and simple syrup are also frequently added. This drink is very similar to the Moscow mule except that the Dark 'n' Stormy has dark rum instead of vodka.
