How long should a keg be refrigerated after purchase before serving?

  1. 12 hours

  2. 24 hours

  3. 36 hours

  4. 48 hours

The correct answer is: 24 hours

When a keg is purchased, refrigerating it for a minimum of 24 hours is crucial for achieving optimal serving temperature and condition. This cooling period allows the beer to stabilize and reach a consistent, cold temperature throughout the keg. If a keg is served too soon after being stored at room temperature, the beer may be too warm, affecting its taste profile and potentially causing excessive foaming when poured. This foundational concept highlights the importance of temperature management in serving beer, as it greatly influences both the flavor and overall experience for the consumer. Proper refrigeration ensures that the beer is refreshing and enjoyable while also maintaining the intended carbonation levels.
