The 151 was for warmth, the Red Bull® Energy Drink was for the extra needed energy and the Jager was added as flavor. Created by Ranger Joe, 2nd Ranger Bat. Mix the Jägermeister herbal Liqueur, Bacardi 151 Rum and Red Bull® Energy Drink Energy Drink in a mug or tall glass. Float a slIce of both Lime and Lemon on top, and serve.
