What bitters are included in the Kingston Club cocktail?

The Kingston Club cocktail includes aromatic bitters, which are a key component that contributes to the drink’s flavor profile. Aromatic bitters have a complex blend of spices and herbs that enhance the overall taste by adding depth and balance to the cocktail. This type of bitters is traditionally used in a variety of classic cocktails, making it a suitable choice for the Kingston Club as well.

In contrast, while other types of bitters such as Angostura and orange bitters are commonly used in many drinks, they are not specifically called for in the Kingston Club recipe. Pineapple bitters would certainly add a fruity element, but they do not fit with the traditional ingredients used in this particular cocktail, which is more aligned with the flavors imparted by aromatic bitters.
