|Ginger beer||10.0cl 3.33oz|
|Dark rum||6.0cl 2.0oz|
The D&S is a classic for a reason -- it's easy, delicious (especially in warm weather), and hard to screw up.
There are some interesting copyright nuances with the D&S, as mentioned by hebug on Reddit:
In the late 1970s, Gosling’s trademarked the Dark ‘n Stormy cocktail to protect their interests abroad. Despite the Dark ‘n Stormy serving as Bermuda’s unofficial drink and traditionally utilizing Gosling’s Black Seal Rum, when other rum companies began promoting their rums in America or Europe for use in a Dark ‘n Stormy cocktail, Gosling’s wanted the theoretical right, though presumably never exercised, to prevent others from capitalizing on their cocktail. Technically, there are a few other trademarked cocktails such as the Painkiller and Sazerac, but trying to enforce these trademarks at thousands of individual bars is patently ridiculous. Instead, Gosling’s has taken the strategy to educate and establish their specific recipe as the Dark ‘n Stormy, by both making their own brand of ginger beer known as Gosling’s Stormy Ginger Beer, and by selling a premixed canned version of their cocktail which I am very curious to try.
