What is "chaser"?

A chaser is a beverage that is consumed immediately after taking a shot of hard liquor. The purpose of a chaser is to help mask the strong taste of the liquor and to cleanse the palate. Common types of chasers include soft drinks, such as cola or lemon-lime soda, or fruit juices like orange or cranberry. Some people also use beer as a chaser for shots of liquor. Chasers are often used to make drinking shots more enjoyable and to help reduce the burning sensation that can be caused by strong liquors. While chasers can help to make drinking more palatable, it's important to remember that they do not reduce the effects of alcohol on the body.
