Gin Fizz vs. Tom Collins

Gin Fizz and Tom Collins side by side: what changes in the recipe, the balance, the strength and the calories.

The difference

Gin, lemon, sugar and soda in both: two of the oldest fizzy gin drinks. The Gin Fizz uses less gin and only a splash of soda, so it is shorter and tarter; the 1876 Tom Collins pours more gin and more soda with less sugar.

By the numbers

They use the same ingredients, in different amounts and built differently. In parts, a Gin Fizz is 1½ gin, 1 lemon, ¼ syrup and 1 soda; a Tom Collins is 1 lemon, 2 gin and 2 soda. By volume, the Gin Fizz is 39% spirit, 26% mixer and juice, 26% citrus and 9% syrup and sugar; the Tom Collins is 39% mixer and juice, 39% spirit, 19% citrus and 3% syrup and sugar. That makes them close cousins on the ratio map.

They are about equally strong in the glass (10.9% and 11.1% ABV), but the Tom Collins is the bigger drink, so it holds more alcohol (1.35 standard drinks against 1.01). The Tom Collins has more calories (about 150 against 130), but the Gin Fizz has more sugar (6.9 g against 3.5 g). Both are shaken and served in a highball.
