What is the first step in cleaning a draft system's beer glass?

The first step in cleaning a draft system's beer glass is to empty the glass to an open drain. This step is crucial because it ensures that any leftover beer or residue is removed before any cleaning process begins. By emptying the glass, you eliminate the risk of contaminating the cleaning solution or hindering the effectiveness of subsequent cleaning steps.

Once the glass is emptied, it can then be appropriately cleaned with hot water or another cleaning agent. Each step in the cleaning process is designed to ensure that the glass is free of beer residue and contaminants that can affect the taste of the beer served in it. Properly preparing the glass by first emptying it sets the stage for effective sanitization and thorough cleaning afterward.
