Gin and Tonic vs. Madras

The difference, by the numbers

They have no ingredient in common: the Gin and Tonic has gin and tonic water, the Madras vodka, cranberry juice and orange juice. In parts, a Gin and Tonic is 1 gin and 2½ tonic water; a Madras is 1 vodka, 1½ cranberry and 1 orange. By volume, the Gin and Tonic is 71% mixer and juice and 29% spirit; the Madras is 71% mixer and juice and 29% spirit. Different bottles, similar balance: that makes them close cousins on the ratio map.

The Gin and Tonic is the stronger drink in the glass (10.7% ABV against 8.0%), but the Madras is the bigger drink, so it holds more alcohol (1.35 standard drinks against 1.13). The Madras has more calories (about 213 against 152) and more sugar (16.7 g against 10.9 g). Both are served in a highball; the Gin and Tonic is built, the Madras shaken.
