Unlike vodka, which is typically 80 proof, though sometimes 100 proof, gin brands vary in strength between those two numbers. So, yes, brand absolutely matters. And like distilled spirits, gin has zero carbs, juniper berry flavoring.
Gin Calories and Proof by Brand
| Brand | Calories per Shot | Proof |
| Beefeater Dry | 114 | 94 |
| Bombay Dry | 104 | 86 |
| Bombay Sapphire | 114 | 94.4 |
| Booth’s | 109 | 90 |
| Burnett’s | 97 | 80 |
| Gordon’s | 97 | 80 |
| Hendrick’s | 107 | 88 |
| Seagram’s | 97 | 80 |
| Tanqueray | 115 | 94.6 |
How Many Calories are in a Gin and Tonic?
Obviously, that’s a loaded question since all gin and tonics are not made equally. If we use a breakdown of 6 ounces tonic and 2 ounces of 94 proof gin (a 3:1 ratio poured into a highball glass), its yields 194 calories. But, you could use more gin, weaker gin, less tonic, substitute club soda, and any other number of variables, so go ahead and take your best guess and put that into the virtual mixologist.
How Many Calories are in a Martini?
Another tough question. But again, we’re going to play around with some common numbers and throw those into the calculator app.
- Dirty Martini: 135 calories (1.5 oz Bombay Sapphire, .25 oz extra dry vermouth .25 oz. olive juice, 3 olives)
- Dry Martini: 132 calories (1.5 oz Bombay Sapphire, .5 oz. extra dry vermouth, 1 olive)
So, what’s the conclusion here? That I used too many rhetorical questions in this post. And that that the brand makes some difference due to strength. For the calorie conscious, it’s more important how much gin you’re drinking and what you’re mixing it with.
