What type of drink component typically goes on the bottom in layered drinks?

In layered drinks, the component that typically goes on the bottom is a lower proof spirit or liqueur. This is because lighter liquids are less dense, allowing them to float on top of heavier ingredients. When creating layered drinks, bartenders often start with the most dense ingredients at the bottom, which are usually higher proof spirits or syrups.

A lower proof ingredient is able to sit on top of the denser components because when poured gently over the back of a spoon, it does not disturb the layers beneath it. This technique is essential for achieving the visually appealing effects characteristic of layered drinks.

Conversely, high proof spirits and flavored liqueurs could be placed above the lower proof ingredient due to their respective densities and flavors. Carbonated beverages generally do not layer well because their effervescence creates a mixing effect that disrupts the layers. Understanding the properties of these drink components is crucial for bartenders when crafting visually stunning cocktails.
