The Beach Bum is a blended rum cocktail built around fresh mango and a sharp hit of lime. Dark rum and peach brandy give it body, while the mango keeps the texture thick enough to feel like a proper drink. It works well when the weather is warm and you want something cold in hand quickly.
The blending time is short, just 10 to 15 seconds, which is enough to break down the mango without turning the whole thing into foam. Pouring over ice keeps it cold without diluting it too fast. If you enjoy mango-forward drinks, our Mango Lassi is a good non-alcoholic alternative on the same theme.
This recipe uses equal parts of rum, brandy and lime juice, so scaling up for a group is straightforward. One mango per batch is the right quantity for the volume of liquid involved.

About the Recipe
This is a blend-and-pour recipe with no cooking involved. The key variable is the mango. Use a ripe one with soft, yielding flesh. An underripe mango will taste sharp and starchy alongside the lime, and the brandy will not balance it well.
Chop the flesh into rough pieces before adding to the blender so it breaks down evenly in 10 to 15 seconds.
The equal-parts ratio of rum, brandy and lime juice holds the drink together. The lime cuts through the sweetness of the peach brandy and mango. Adjusting any one of the three without adjusting the others will shift the balance noticeably, so keep the ratio intact when scaling.
Why You Will Love This Recipe
The strongest reason to make this is how little time and effort it takes. There is no syrup to prepare, no muddling, and no special technique. Everything goes into a blender together and the drink is ready in under two minutes.
The texture is smooth and thick from the fresh mango, which makes it feel more substantial than a standard shaken cocktail. The peach brandy adds a gentle sweetness that works well with mango without making the drink taste artificial.
For anyone curious about what fresh fruit does in a blended cocktail, this recipe is a clear and easy demonstration.
Cooking Tips
The most common beginner mistake is blending too long. Beyond 15 seconds, the mixture picks up air and the texture turns foamy. Keep the blending short.
Do not skip the ice in the glass. The drink comes out of the blender at room temperature because no ice goes into the blender itself, so the ice in the glass does the chilling. Use a large glass to give the ice room and avoid overflow when pouring.
Top Tips
- Use a fully ripe mango. The flesh should be soft and fragrant. An underripe mango makes the drink taste sharp and starchy.
- Blend for 10 to 15 seconds only. Over-blending creates foam and changes the texture.
- Do not add ice to the blender. Ice goes only in the glass so the drink stays smooth rather than watery.
- Measure the rum, brandy and lime juice in equal parts. The balance of the drink depends on this ratio.
- Serve immediately after pouring. The drink separates if it sits too long without being stirred or sipped.
- A thick lime slice on the rim holds better than a thin one and gives a small squeeze of fresh juice with each sip if pressed.
Serving and Storing Suggestions
Serve the Beach Bum immediately after pouring into the ice-filled glass. It does not store well once blended because the mango begins to separate and the drink loses its texture within 20 to 30 minutes.
If you are making it for a group, blend each batch just before serving. The recipe scales easily since all three liquids use the same measure.
For a non-alcoholic version, replace the rum and brandy with mango nectar and a splash of peach juice, and follow the same blending method.

Nutrient Benefits
Fresh mango contributes vitamin C and vitamin A. Lime juice adds further vitamin C. These are ordinary nutrients found in most fresh fruits.
The mango also provides some natural dietary fibre, which stays intact through blending. The alcohol content from the dark rum and peach brandy is significant, so this is a drink to enjoy in moderation.

Frequently Asked Questions
Can I use frozen mango instead of fresh mango?
Yes, frozen mango works in this recipe. Thaw it slightly before blending so it breaks down evenly in 10 to 15 seconds. Fully frozen chunks can strain a standard home blender and may leave unblended pieces. The flavour will be close to fresh mango, though a ripe fresh mango will generally give a sweeter and more fragrant result.
What can I use instead of peach brandy?
Apricot brandy is the closest substitute and will not change the drink significantly. Plain brandy also works, though the drink will lose some of the stone-fruit sweetness that peach brandy adds. Avoid flavoured liqueurs that are very sweet, as the lime juice is calibrated against the moderate sweetness of peach brandy.
Why does my blended drink taste too sharp or sour?
The most likely cause is an underripe mango. A mango that is not fully ripe lacks the natural sweetness needed to balance the lime juice. Check that the flesh is soft and smells fragrant before using it. If your mango was ripe and the drink is still too sharp, reduce the lime juice slightly in your next batch, as lime sizes vary and some limes yield more juice than others.
Can I make a large batch of this ahead of time for guests?
It is better to blend each batch fresh. Blended mango separates and oxidises within 20 to 30 minutes, and the drink loses its smooth texture. If you are serving a group, measure and chop everything beforehand so each batch takes only a few seconds to blend and pour. That way the drinks stay fresh without any waiting time.
Is there a way to make this cocktail without alcohol?
Replace the dark rum with mango nectar and the peach brandy with peach juice or a small amount of peach syrup. Keep the lime juice as it is. The result will be a mango-lime blended drink that follows the same method. You may want to reduce the lime juice slightly since there is no alcohol to temper the sharpness. Pour over ice and garnish the same way.
