What is Blue Marlin?
The Blue Marlin is a contemporary tropical cocktail that takes its name and visual identity from the iconic blue marlin fish, one of the most prized game fish in sport fishing culture and a recurring symbol of tropical sport fishing destinations in the Caribbean, Florida Keys, and Hawaii. The drink belongs to the broader family of berry-forward modern American cocktails that emerged through the 2000s and 2010s, when bartenders began creating colorful variations of classic templates using fruit-flavored schnapps and contemporary mixers. The Blue Marlin specifically pairs blueberry schnapps with white rum, sour mix, and lemon-lime soda to create a tropical drink with a distinctive deep magenta-purple color that visually evokes the ocean depths where blue marlin are caught. The cocktail belongs to the same family of berry-forward party drinks as the Blue Whale, the Blueberry Lemonade, and the Black-and-Blue, all of which leverage blueberry schnapps for color and flavor in casual cocktail formats. The Blue Marlin has become particularly popular at sport fishing destinations, beach bars, and tropical-themed gatherings where the colorful visual presentation and casual preparation align with relaxed coastal entertaining. The drink also benefits from its connection to white rum's broader Caribbean heritage, which has been integral to tropical cocktail making since the rise of tiki bar culture in the 1930s and 1940s pioneered by Don the Beachcomber and Trader Vic.
Fans of bright blue drinks like the Blue Lagoon will appreciate the balance of berry sweetness and citrus tang found in the Blue Marlin. The combination creates a crisp, thirst-quenching cocktail with a light effervescence that keeps each sip refreshing. Looking for more colorful drinks?

Why You'll Love It?
- The deep magenta-purple color comes naturally from blueberry pigments: the actual finished drink leans toward dramatic dark purple rather than electric blue, which is more visually interesting than artificial colors and photographs beautifully.
- Use a quality blueberry schnapps such as DeKuyper Blueberry or Hiram Walker: cheaper schnapps can taste artificially sweet and one-dimensional, while quality bottles deliver the candy-blueberry character that defines this drink.
- For a more intense royal blue color, add a quarter ounce of blue curaçao: the combination of magenta-purple blueberries with electric blue curaçao produces a stunning richer royal blue final color closer to what the name suggests.
- Build directly in the glass rather than shaking: the lemon-lime soda will go flat immediately if shaken, and the drink follows the casual tropical highball tradition where preserving carbonation matters more than emulsification.
- Batches beautifully for parties: combine the rum, schnapps, and sour mix in a pitcher, refrigerate, and add lemon-lime soda to individual glasses at pour time for the freshest possible results throughout the entire serving session.
