What is one common method to verify the quality of beer during delivery?

Inspecting the physical condition of the keg is a common method to verify the quality of beer during delivery because it allows one to identify potential issues that could affect the beer's integrity. By examining the keg, one can look for signs of physical damage, such as dents or leaks, which might indicate that the beer has been compromised during transport. A well-maintained keg is vital for preserving the beer’s quality, as physical damage can also lead to contamination or spoilage.

The other options, while relevant in a broader quality assurance context, do not directly assess the immediate quality of the beer being delivered. For instance, assessing the design of packaging can offer clues about the brand’s commitment to quality but does not provide direct evidence. Checking the brewery’s reputation can give a general sense of quality but does not reflect the condition of the specific batch being delivered. Reviewing government regulations pertains to compliance and safety standards, which are important but do not measure the actual quality of the beer itself in transit.
