Best Rum for Mojito: UK Supermarket Guide 2025

A mojito lives or dies by its rum. The spirit makes up roughly 40% of the drink—so choosing wisely matters. White rum dominates UK supermarket shelves, but not all are created equal. We've sourced and tested the most accessible options to help you build a cracking home bar without the hunt.

What is a Mojito?

A mojito is a Cuban highball combining white rum, fresh mint, lime juice, sugar, and soda water, served over ice. It's refreshing, easy to batch for guests, and forgiving enough for beginners—provided your rum isn't thin or spiritless.

Why Rum Choice Matters for Mojitos

The spirit is the backbone of your drink. A good rum brings warmth and subtle flavour—vanilla notes, a touch of sweetness—that lifts the mint and lime instead of getting lost behind them. Cheap white rum often tastes thin and acrid, overpowering the fresh botanicals you've just crushed.

The best mojito rums are column-distilled, around 37.5–40% ABV, and aged just enough to round out raw alcohol burn. Light oak aging (6 months to 2 years) adds depth without competing with mint. When you're shopping at Tesco, Sainsbury's, or Asda, look for words like "aged," "premium," or "aged white."

Top UK Supermarket Rums for Mojitos

Bacardi Superior (37.5% ABV)

The classic choice. Bacardi is stocked everywhere—Tesco, Sainsbury's, Asda, Morrisons—and costs around £15–18 per 70cl bottle. It's column-distilled, clean, and mixes reliably. You won't find complexity, but you will find consistency. Perfect for large gatherings when you're making 12 mojitos in a row.

Captain Morgan White (37.5% ABV)

A notch richer than Bacardi, with a whisper of vanilla and a softer finish. Widely available at major supermarkets, often competitively priced (£16–19). It's slightly sweeter, which some prefer in a mojito; others find it masks the mint. Worth trying if you want a touch more character.

Mount Gay Eclipse (40% ABV)

A Barbadian standard. At 40% ABV, it's fractionally stronger and more flavourful than Bacardi. You'll pay a bit more (£18–22), but the extra depth—subtle fruit notes, a creamy mouthfeel—justifies it. Sainsbury's and Tesco stock it regularly. Mojitos made with Mount Gay taste noticeably smoother.

Havana Club Blanco (37.5% ABV, where available)

Cuban rum with a cult following. Harder to find in standard supermarket chains due to US embargo complexities, but some larger Tesco and Sainsbury's branches stock it, and specialist off-licences often do. If you spot it (£17–20), grab it. It's the rum used in Havana bars—clean, well-balanced, and made for mojitos.

Appleton Estate White (40% ABV)

A Jamaican option with more presence. Appleton is increasingly common in UK supermarkets and brings a fruitier, slightly funkier profile than Bacardi—still fresh enough for mojitos, but with character. Expect to pay £18–23. It's excellent if you want your mojito to taste a little less generic.

Budget vs. Premium: What's Worth Paying For?

You don't need a £40 bottle to make a great mojito. The drink's fresh mint and lime do heavy lifting. However, the difference between a £15 supermarket own-brand white rum and a £20 Bacardi or Mount Gay is noticeable—smoother, less harsh, better balance.

Our recommendation: spend £18–22 per bottle. You'll get better consistency, a more pleasant drinking experience, and better value per mojito than cheaper options. A 70cl bottle yields roughly 10–12 drinks, so you're looking at £1.50–2 per cocktail for spirit alone.

If you're hosting 20+ people, buy two bottles of a reliable mid-range rum rather than one expensive one. Bacardi and Mount Gay scale brilliantly.

How to Spot Quality White Rum at the Supermarket

• Check the ABV: Look for 37.5–40%. Anything below 37.5% often tastes thin.
• Read the label: Words like "aged," "premium," or "blended" suggest more care than generic "white rum."
• Avoid plastic bottles: Glass signals quality and proper storage.
• Look at the price range: £15–25 is the sweet spot. Below £12, you're likely getting rough spirit.
• Ask the staff: Tesco and Sainsbury's wine teams often know which rums mix best.

Making the Perfect Mojito at Home

Once you've chosen your rum, technique matters. Here's the home bar formula:

• 10–12 fresh mint leaves (bruise gently, don't shred)
• ½ lime, cut into wedges
• 2 teaspoons caster sugar (or ½ oz simple syrup)
• 50ml white rum
• 75ml soda water (or to taste)
• Ice

Muddle mint and lime in a tall glass until fragrant (10 seconds). Add sugar and stir. Pack with ice, pour rum, top with soda, and stir gently. A sprig of fresh mint and a lime wheel finish it.

The key: don't over-muddle. You want bruised mint releasing oils, not pulped leaves turning bitter. Many beginners crush too hard. Gentle is better.

Storing Your Rum at Home

White rum keeps indefinitely in a cool, dark place—a kitchen cupboard or pantry is ideal. Unlike wine, spirits don't age in the bottle, so there's no rush to drink it. Once opened, white rum stays good for years. Keep the cap on between pours to avoid oxidation.

If you're an occasional mojito maker, one 70cl bottle will last months. If you're a regular host, consider buying a second bottle before summer entertaining season kicks off.

Beyond the Mojito: Other Cocktails with Your Rum

A good white rum isn't just for mojitos. You can use the same bottle for rum cocktails like daiquiris, ti' punches, or rum punches.

Where to Buy: Supermarket vs. Specialist

UK supermarkets carry decent selection at fair prices. Tesco, Sainsbury's, Asda, and Morrisons all stock Bacardi, Captain Morgan, and Mount Gay. For wider choice and expert advice, try specialist off-licences or online retailers like Master of Malt, which stocks harder-to-find options and offers detailed tasting notes.

Frequently Asked Questions

Can I use any white rum for a mojito?

Technically, yes, but quality varies wildly. Supermarket own-brands below £12 often taste harsh and thin. For a genuinely pleasant mojito, stick to branded rums in the £15–22 range.

What's the difference between white rum and silver rum?

In practice, none. Both terms describe unaged or lightly aged rum with minimal colour. Supermarkets use them interchangeably. Pick by brand and price, not label wording.

Is spiced rum okay for mojitos?

No. Spiced rum (darker, sweetened, with added spices) will clash with fresh mint and lime. Stick to white rum.

How many mojitos does a 70cl bottle make?

Roughly 10–12, depending on pour size. A standard 50ml measure is typical; generous home pours might yield 9–10.

Can I make mojitos in advance for a party?

Partially. Prepare the sugar-lime-mint base in advance. Add rum, ice, and soda water just before serving to keep it fresh and fizzy. Pre-mixing dulls the taste.

Which supermarket rum offers the best value?

Bacardi Superior is the most consistent supermarket buy at a fair price. Mount Gay offers slightly better flavour for a small premium. Both scale well for entertaining.

Do I need to spend more if I'm making mojitos for guests?

Not necessarily. A reliable mid-range rum like Mount Gay or Bacardi works brilliantly in volume. Guests care more about fresh mint and cold ice than premium spirit in a mixed drink.

Final Pour

The best rum for mojitos isn't the most expensive—it's the one that tastes clean, smooth, and doesn't overpower fresh mint and lime. In UK supermarkets, Bacardi Superior, Mount Gay Eclipse, and Appleton Estate White are your safest bets, all priced fairly and widely stocked. Pick one, buy a bunch of fresh mint and limes, and start building your home bar confidence. The Cocktail Pub is here whenever you need a recipe or technique tip.
