Kona Grill’s The Rum Drink is exactly as direct as its name. A Barbados rum base gets rounded with coconut rum, then orange, pineapple and grenadine turn it into an easygoing tropical punch. The key is keeping that fruit bright enough that the aged rum still shows through.
This is not a secret restaurant formula. Kona Grill tells guests what goes into the glass, but it does not publish the pours. The proportions here are a practical home reconstruction using the five ingredients on the current menu.
What Kona Grill Actually Serves
Current Kona Grill beverage menus describe The Rum Drink with Mount Gay Eclipse rum, Haven coconut rum, orange, pineapple and grenadine. A current Riverton, Utah menu lists it at $15, alongside the restaurant’s other signature cocktails. Other location pages show the same ingredient description, although local selection and pricing can change.
The menu does not specify whether “orange” and “pineapple” mean fresh juice or a packaged bar juice, and it does not publish measurements, glassware or garnish. This version uses ordinary unsweetened juices and a restrained quarter ounce of grenadine. The result matches the published flavor outline without pretending to be Kona Grill’s internal recipe.
Kona Grill also gives no creation story or credited bartender. It is safest to describe the drink as the chain’s tropical rum punch, not as an invented classic with a documented birthplace.
Why Typical Copycats Fail
The first problem is too much coconut rum. Coconut should soften the Barbados rum and leave a clear aroma, not turn the whole glass into candy. A half ounce is enough when pineapple and grenadine already bring sweetness.
The second problem is an oversized grenadine pour. Grenadine adds berry-like pomegranate flavor as well as color. More than a quarter ounce can bury the orange, stain the drink an opaque red and make the finish sticky. Use real grenadine rather than bright red corn syrup if possible.
Finally, simply stirring the ingredients over ice misses the light foam that makes a pineapple drink feel polished. A firm shake aerates the juice, blends the two rums and creates a lively top without needing soda.
The Key Technique: Protect the Rum Base
Mount Gay Eclipse has vanilla, warm spice and toasted notes that can disappear behind tropical juice. Measure the rum first, then keep the combined orange and pineapple to two and a half ounces. That is enough juice for a tall, refreshing drink without reducing the base to a background flavor.
Use cold juice and solid ice. Shake until the tin is frosty, then strain over fresh ice rather than dumping in the cracked shaker ice. Fresh ice keeps the drink colder and slows later dilution.
If your pineapple juice is very sweet, reduce the grenadine to one barspoon. If it is sharp or unsweetened, the full quarter ounce will usually balance it. This small adjustment is more useful than adding extra coconut rum.
Make a Pitcher for Six
Combine 9 oz (270 ml) Mount Gay Eclipse, 3 oz (90 ml) Haven coconut rum, 6 oz (180 ml) orange juice, 9 oz (270 ml) pineapple juice and 1 1/2 oz (45 ml) grenadine in a covered pitcher. Refrigerate for up to four hours and stir again before serving because the juices will settle.
For the best texture, shake each 4 3/4 oz (142 ml) serving briefly with ice and strain over fresh ice. For faster service, stir 6 oz (180 ml) cold water into the chilled pitcher just before pouring. Do not leave ice melting in the batch.
The Kona Sunset Mocktail
A useful zero-proof version needs more structure than mixed fruit juice. A 0.0% dark cane spirit supplies molasses, vanilla and spice, while unsweetened coconut water gives the drink a gentle tropical finish. The same orange, pineapple and grenadine keep the connection to the restaurant drink clear.
Check the cane spirit label if complete alcohol avoidance matters. Products labeled nonalcoholic may contain trace alcohol, while a 0.0% statement is more specific. Shake the mocktail hard so its pineapple foam looks and feels like the cocktail version.
The Rum Drink works best when it stays simple: measured coconut, restrained grenadine and enough aged rum character to hold the fruit together.
