How long should a keg be refrigerated after purchase prior to serving?

Refrigerating a keg for 24 hours prior to serving is recommended to ensure that the beer reaches the optimal serving temperature. When a keg is delivered, particularly if it has been transported under varying conditions, it might not be at the appropriate temperature for serving immediately. A 24-hour refrigeration period allows the beer to cool evenly and prevents issues like excess foam, which can occur if beer is served too warm.

Serving beer at the correct temperature is crucial to achieving the best flavors and aromas. Each style of beer has its ideal serving temperature range, but in general, cooling the beer sufficiently enhances the overall drinking experience. A keg that has not been chilled for adequate time may result in foaming issues and a less enjoyable flavor profile. Therefore, the 24-hour recommendation balances ensuring the keg is adequately chilled while accounting for standard handling and transportation practices.
