A standard gin (40% ABV) does contain 66 calories per ounce. That means a Gin and Tonic consisting of a single shot gin (1.5 ounces) and light tonic water (4.5 ounces) contains 118 calories per serving.
That's significantly less than a pint of beer which contains around 200 to 250 calories depending on the type and brand of beer. A large glass of wine (250ml) will also account for 226 calories - almost double the G&T.
Yet, the amount of calories in gin varies depending on the style of gin, amount of sugar and alcohol in it. The higher one or both of these, the more calories a shot of gin contains. So let's look at this in more detail. You can also find popular gin brands ranked by calories for a better overview.
How many calories are in one shot of gin?
One shot of gin equals 1.5 ounces or roughly 45 ml. One such serving of gin (40% ABV) contains about 97-98 calories. In turn, a 37.5% ABV gin (like Gordon's in the UK) has 93-94 calories per shot.
As you can see, the calories reflect the actual alcohol content. Another example of how much of a difference this can make: there are 112 calories in one shot of Navy Strength Gin (57% ABV).
Calories in an ounce of gin
Converted into an ounce, it means there are 66-67 calories in an ounce of gin (40% ABV). A lower ABV Gin bottled at 37.5% contains 62-63 calories. A Navy Strength contains 75 calories per ounce.

The number of calories in your cocktail or Gin and Tonic highly depends on the gin used to make the drink. Keeping that in mind, here is an overview of the number of calories in different gins.

Finding out how many are in a gin
As you can see in the chart, the number of calories in gin strongly correlated with the amount of alcohol it contains. That is because gin mostly consists of ethanol (alcohol), water, and a tiny amount of sugar. One gram of ethanol is roughly 7 calories.
This correlation of ABV to calories also exists in all other spirits like Vodka, Rum, Whiskey, Brandy, or Tequila. Also, when comparing gin to vodka, the number of calories per 1 ounce will be equal or almost equal when choosing products that contain the same amount of alcohol.
So, the easiest way to determine the number of calories that are in a gin is by looking at the proof/ABV.
How many calories are in a Gin and Tonic?
Drinks like the Gin and Tonic are typically known as diet cocktails. But how many calories does the drink really contain? Let's start by looking at the typical measurements: a Gin and Tonic made with 1.5 ounces, or one shot, of gin and 4.5 ounces of tonic water.
The shot of gin equals 98 calories and 4.5 ounces of premium Indian tonic water are about 47 calories, making this standard Gin and Tonic serve 145 calories. As 4.5 ounces of light tonic water only contain 20 calories, choosing the lowest-calorie gin in our list paired with a light tonic will get you a drink that's only 113 calories in total.
