What does the term "straight up" mean in bartending?

The term "straight up" in bartending refers to chilled liquor that is served in a chilled glass without any ice. This means that the drink has been shaken or stirred with ice to chill it and then strained into a glass, ensuring that the beverage is cold while remaining free of ice, which could dilute the drink as it melts. This method of serving allows the full flavor profile of the liquor to come through, providing a neat presentation.

This technique is often used for cocktails made with spirits like vodka or gin, and it is popular because it showcases the quality of the liquor itself. The service style emphasizes purity and clarity in flavor, which aligns with the expectations of many patrons who appreciate their drinks served in this way.
