Every industry has its own terminologies. As a bartender, you should know your profession very well, and knowing these terms is a must. Even as a customer, knowing them would help you have a more exciting bar experience.

Chaser
Anything that is consumed quickly after a shooter or straight (neat) shot of alcohol. A shaker masks the taste of the original shooter or creates a different taste.

Cobbler
A tall drink of any liquor served in a collins or highball glass with shaved or crushed ice and garnished with fresh fruit and mint sprigs.

Collins
A drink akin to a sour which is served in a tall glass with soda water or seltzer water.

Cooler
A drink consisting of ginger ale, soda water, and a fresh spiral or twist of citrus fruit rind, served in a collins or highball glass.

Dash
A few drops or a very small amount of an ingredient.

Double
A drink with double the amount of liquor.

Float
When one alcohol sits on top of another alcohol in a shooter glass.

Free pour
To make and mix drinks without using a measuring device; to pour straight from a bottle.

Frost
To dip a glass in water, let it drain and then put it in the freezer, thereby creating a layer of frost around the glass; it works well for beer mugs.

Highball
Any spirit served with ice and soda water in a medium to tall glass (often a highball glass).

Layer
Layering a shot or drink is done the same way as floating. The heavier alcohol goes on the bottom and the next, lighter alcohol gets floated on top using a careful pour down the side of the glass or a pour over an inverted spoon.

Lowball
A short drink made of spirits served with ice, water or soda in a small glass.

Neat
Drink served at room temperature without ice. If someone asks for a whiskey neat, they are asking for a shot straight out of the bottle.

On the rocks
A wine or liquor poured over cubed ice.

Shooter
A shooter (or shot) is a 1-2 ounce serving of either straight liquor or a mixture of alcohol that is meant to be drank (or shot) in one gulp.

Sling
A tall drink made with either brandy, whiskey or gin, with lemon juice, sugar and soda water. It is served both hot and cold.

Sour
A short drink consisting of liquor, lemon/lime juice and sugar.

Virgin
A drink without any alcohol in it.
