Head to head
Chapman and Roy Rogers side by side: what changes in the recipe, the balance, the strength and the calories.
The difference, by the numbers
Both have grenadine. Only the Chapman has orange soda, lemon-lime soda, alcohol-free aromatic bitters, cucumber and lime juice; only the Roy Rogers has cola. In parts, a Chapman is 1 orange soda and 1 lemon-lime soda; a Roy Rogers is 1 grenadine and 22 cola. By volume, the Chapman is 94% mixer and juice and 6% syrup and sugar; the Roy Rogers is 96% mixer and juice and 4% syrup and sugar. That makes them close cousins on the ratio map.
They are about equally strong in the glass (both 0.0% ABV), and they hold about the same alcohol (0.00 standard drinks each). The Chapman has more calories (about 209 against 98) and more sugar (47.6 g against 21.5 g). Both are built and served in a highball.
