How Many Calories Are in a Rum and Mixer?

How Many Calories Are in a Rum and Mixer?

If you enjoy a glass of rum, it’s worth knowing how many calories are in your favourite drink. Calories in spirits often depend on the alcohol content and the mixer you choose. Let’s take a look at the calories in a rum with 40% ABV, the typical strength for most white, dark, and spiced rums.

Calories in Rum

A single 25ml measure of 40% ABV rum contains about 60–65 calories. A double (50ml) measure is around 120–130 calories. Like gin, the rum itself is relatively low in calories, but mixers can quickly raise the total.

Here are some examples:

• 25ml rum with cola (125ml) – about 140 calories
• 25ml rum with diet cola (125ml) – about 65 calories
• 25ml rum with ginger beer (125ml) – about 150 calories
• 25ml rum with soda water and lime – about 65 calories

For comparison:

• A pint of lager is around 200 calories
• A glass of red wine is about 160 calories
• A glass of prosecco is about 90 calories

So, a rum and diet mixer can be a smart option if you want a lower-calorie drink.

Tips for a Lower-Calorie Rum

• Add fresh lime or orange slices for flavour without extra calories
• Try your rum neat or over ice if you enjoy bold flavours
