How Many Calories Are In a Gin and Tonic (and Other Favourite Drinks)?

According to Drinkaware, a gin and tonic with 25ml of gin (with 37.5% ABV) has 97 calories. However, with such a range of different gins and tonics out there, all containing a variety of ingredients, the calories in a G&T will depend on the type of gin, as well as the type of tonic used.

Today, many have become more concerned about their health, and the food and drink they put into their bodies (and rightfully so!) – looking for the “healthiest” drinks with the fewest calories to help them with this.

However, drinking alcoholic beverages, such as ILoveGin’s favourite, expertly crafted gins, should always be considered as a treat to be indulged in sensibly.

While sadly, there’s no such thing as a healthy gin, or a healthy G&T for that matter, depending on the bottle you go for, it could be substantially lower in calories than other common drinks – including beer and wine.

Here, ILoveGin explores how many calories are in gins, tonics and more.

How Many Calories Are in Gin?


Many gins offer comparably lower calorie counts than other alcoholic beverages – a 25ml measure of gin with fruit juice or a mixer can amount to 108 calories, whereas a 175ml glass of wine can come to 159 calories, and a pint of cider at 216 calories.

However, as previously mentioned, not all gins will hold the same calories. Depending on their ingredients, certain gins will have more than others – for example, 100ml of Greenall’s Blueberry Gin contains 207kcal, while 100ml of Bombay Sapphire Gin holds 236 calories.

Certain flavoured gins can also have considerably more sugars than others. According to one survey, sponsored by Greenall’s, some flavoured gins could hold up to 15 teaspoons of sugar per bottle, while others (including Greenall’s own Blueberry Gin) contain zero added sugars.


How Many Calories Are in Gin and Low Calorie Tonic?


As the name suggests, swapping higher calorie mixers with a “low calorie tonic” can lower the calorie count of your G&T.

But what’s the difference between regular tonics and diet ones? Diet tonics will typically be lower in calories than regular tonics. For example, 100ml of Fever Tree Indian Tonic Water holds 35.61kcal, whereas 100ml of Fever Tree Refreshingly Light Indian Tonic Water holds 15kcal.

Regular tonic water will most likely contain sugar, while in contrast, diet tonics will utilise alternative sweeteners, both natural and artificial – the type of sweeteners varying from brand to brand.


What Is the Lowest Calorie Cocktail?


Gin & Tonic cocktails can be substantially low in calories, especially when using light tonics and low calorie gins.




There are a number of cocktails you can make low-cal, including:

  • Mojitos
  • Martinis
  • Vodka & Soda
  • Bloody Mary

The calories you get from a cocktail won’t just be down to the spirits you use (e.g. the gin), but can also come from the mixers included. When looking to make a low calorie cocktail, it’s therefore important to consider all the ingredients used for this.
