What does "W" represent on the soda gun?

The "W" on the soda gun represents Water. In bartending, the soda gun is an essential tool used to dispense various liquids quickly and efficiently. Each letter on the soda gun corresponds to a specific product, and "W" is designated for water, which is often used as a mixer or a filler in cocktails, soda drinks, and other beverages. Having a dedicated water line is crucial for bartenders to prepare drinks properly, ensuring that they can mix drinks with both soft drinks and other mixers without losing time to fetch water from another source.

The other options, while they may seem plausible within the context of a bar, do not accurately align with the standardized usage of the soda gun. Whiskey, for instance, would be represented differently, as it is a specific liquor rather than a common mixer like water. Whipped cream and Worcestershire sauce are also not items that would be dispensed from a soda gun, as they are generally not served in this fashion and wouldn't typically be needed in quick, on-demand scenarios where a soda gun is beneficial. Understanding this crucial aspect of bar equipment helps ensure that drinks are made efficiently and correctly.
