Head to head

Gin Fizz vs. Rum Collins

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

The difference, by the numbers

Both have lemon juice and soda water. Only the Gin Fizz has gin and simple syrup; only the Rum Collins has sugar, lime juice and white rum. In parts, a Gin Fizz is 1½ gin, 1 lemon, ¼ syrup and 1 soda; a Rum Collins is ¾ lemon, ¼ lime, ¾ rum and 1 soda. By volume, the Gin Fizz is 39% spirit, 26% mixer and juice, 26% citrus and 9% syrup and sugar; the Rum Collins is 35% mixer and juice, 35% citrus, 26% spirit and 4% syrup and sugar. That makes them close cousins on the ratio map.

The Gin Fizz is the stronger drink in the glass (10.9% ABV against 10.1%), but being smaller it holds about the same alcohol (1.01 standard drinks each). Calories are close (about 130 and 129), but the Gin Fizz has more sugar (6.9 g against 5.4 g). Both are served in a highball; the Gin Fizz is shaken, the Rum Collins built.
