what are the mini bottles of liquor called

[RichardLynn]

The small, single-serving bottles of liquor are formally and most commonly referred to as "miniatures." This term is the standard designation used within the beverage industry and by regulatory bodies for a small bottle of a spirit, liqueur, or other alcoholic beverage. The typical volume for a miniature is 50 milliliters, which is equivalent to a single shot.

In addition to the official terminology, these bottles are known by a variety of colloquial and informal names that vary by region and context. One of the most prevalent informal terms is "nip." Another common name is "airline bottle" or "airplane bottle," a descriptor derived from their widespread use for serving single portions of spirits on commercial flights.

Furthermore, they are often called "shooters," a name that directly alludes to the single-shot volume of their contents. The terms "mini-bottle" and "mini" are also frequently used as straightforward, descriptive names that reference their diminutive size. While "miniature" remains the most precise and formal term, these other names are widely understood in common parlance.
