Best Rum for Mojitos in the UK: 3 White Rums Compared

For a classic Mojito, start with a standard white rum: BACARDÍ Carta Blanca is the clean familiar route, Havana Club Original 3 Años is the Cuban aged-white reference, and Planteray 3 Stars is the more characterful blended-rum comparison. None is a universal winner. The right choice depends on whether you want the mint and lime to lead or the rum to remain more obvious after soda and dilution.

Research checked 22 September 2026. We used the recognised IBA specification and current producer pages. We did not receive these bottles for coverage or run a blind tasting, so producer flavour descriptions are identified as such and no frozen supermarket price is presented as today's deal.

Three white rums to compare for a Mojito

This table compares documented product direction, not tasting medals or an affiliate payout. Use the matcher above to open the exact bottle route, then check size, seller, delivery and the delivered label before buying.

The recognised Mojito reference

The International Bartenders Association specifies 45ml white Cuban rum, 20ml fresh lime juice, six mint sprigs, two teaspoons of white cane sugar and soda water. Mint, sugar and lime are mixed, a splash of soda and ice are added, then the rum and more soda are lightly stirred through.

That specification is why this guide starts with white rum. Gold, dark, spiced and flavoured rum can make enjoyable variations, but they should not be compared as though colour, added flavour and sweetness were identical.

What to read on a supermarket bottle

What about Asda Mojito rum or supermarket own label?

An Asda or other supermarket own-label white rum can make a Mojito if the current bottle is actually labelled as standard white rum. Supermarket ranges, bottle sizes and online listings rotate, so a search result or old product image is not enough. A Mojito-flavoured product, premixed bottle, spiced rum or lower-strength spirit drink is not a like-for-like substitute for the white rum in the IBA recipe.

1. Confirm the full product name and whether the label says white rum.
2. Compare the same bottle size, or calculate the price per 70cl.
3. Check the alcohol strength, seller and delivery charge.
4. Use the same 45ml measure, lime, mint, sugar, soda and ice before judging it against another bottle.

A controlled home Mojito method

1. Add 20ml fresh lime juice and two level teaspoons of white sugar to a tall glass.
2. Add six mint sprigs and press gently in the liquid; do not grind leaves and hard stems into fragments.
3. Add 45ml white rum and a small splash of chilled soda.
4. Fill with crushed or cracked ice, churn briefly from the bottom and top with more soda.
5. Taste before adding more sugar. Garnish with a fresh mint crown away from the straw.

Keeping the recipe fixed matters more than chasing a bottle ranking. Change one variable at a time and record it; otherwise a sweeter lime, tired mint or extra soda can be mistaken for a difference between rums.

How to compare two rums fairly

Make half-size drinks with identical lime, mint, sugar, soda and ice. Measure 25ml rum into each, label the glasses underneath and keep the final volume equal. Ask whether the rum remains identifiable, whether sweetness needs changing and whether the finish clashes with mint. Reveal the bottles only after scoring, then compare the delivered cost per 45ml serve.

Common Mojito failures

• Bitter and grassy: the mint was shredded or hard stems were ground. Press lightly.
• Flat: use freshly opened, well-chilled soda and add it late.
• Too sweet: start from two level teaspoons and account for sweetened or spiced rum.
• Watery: use plenty of cold ice and a short churn; a small amount of melting is desirable, uncontrolled dilution is not.
• No rum character: reduce soda or sugar before buying a more expensive bottle.

Frequently Asked Questions

What is the best white rum for Mojitos in the UK?

There is no universal winner. BACARDÍ Carta Blanca is the clean familiar reference, Havana Club 3 Años is the Cuban aged-white route, and Planteray 3 Stars is the more characterful blended-rum comparison. Keep the recipe fixed and choose the direction you prefer.

Can supermarket own-label white rum make a good Mojito?

Yes, if the current bottle is standard white rum and you compare like-for-like size and strength. Fresh lime, mint, cold soda, ice and measured sugar can matter more than a small shelf-price difference.

Can I make a Mojito with dark or spiced rum?

Yes, but it becomes a deliberate variation with a different colour, flavour and possibly sweetness. Reduce sugar only after tasting a measured first serve.

Is expensive rum necessary?

No. Start with a correctly labelled white rum and control the fresh ingredients and dilution before paying more for the bottle.

Should I muddle the mint?

Press it gently enough to release aroma. Grinding leaves and stems creates fragments and can add harsh vegetal notes.

How many Mojitos from a 70cl bottle?

At 45ml per drink, a 70cl bottle gives fifteen full measures with 25ml remaining, before spillage.
