Is Chapman a cocktail or a mocktail?

The short answer is: Chapman can be either. The name describes a Nigerian party-drink style, not a guarantee about alcohol content.

When Chapman is a mocktail

A Chapman is non-alcoholic when every ingredient is alcohol-free. That usually means citrus soda or juice, fruit syrup, cucumber, citrus slices, and alcohol-free bitters or another spice component.

When Chapman is a cocktail

Some recipes use aromatic bitters that contain alcohol, while others add gin, vodka, or another spirit. Even a small dash of traditional bitters means the recipe may not be strictly alcohol-free.
