After washing, what is the next cleaning step recommended for draft glasses?

Rinsing draft glasses in cold water after washing is recommended because it helps to remove any remaining detergent or soap residue that could affect the taste of the beer served in the glass. Cold water is effective in this context because it is less likely to create additional foam, which can occur with warmer water. It also helps in cooling the glasses slightly, which can enhance the serving experience for certain styles of beer that benefit from being served in chilled glassware.

Choosing hot water for rinsing would not be optimal as it may not effectively rid the glass of all soap residue and could potentially be harmful to the glass if it causes thermal shock. Soaking glasses in detergent would not be appropriate for a post-washing step, since the glasses are already presumed to be washed. Drying with a cloth, although important in some contexts, is typically a final step that follows rinsing and is not the immediate next step after washing. Thus, rinsing in cold water is the most appropriate choice to ensure the glasses are clean and ready for beer service.
