Started drinking the Dark & Stormy 30+ years ago on my honeymoon to Bermuda. The classic recipe uses Goslings Black Rum, Ginger Beer (not ale) and a twist of lime. I add a dash of orange bitters and use lemon instead of lime. My choice of Belvoir Ginger Beer (which contains lemon juice) adds a sharp jolt of ginger that's on the edge of fiery and cuts the sweetness of the rum.
