Final answer:
When examining bottled beer, look for clarity, carbonation level, and aroma.
Step-by-step explanation:
When examining bottled beer, there are several things to look for. Firstly, check the clarity of the beer by holding the bottle up to the light and seeing if there are any particles present. Additionally, pay attention to the carbonation level by observing the bubbles in the beer. Good quality beer will have a steady stream of small bubbles. Finally, analyze the aroma of the beer by taking a sniff from the bottle. The aroma should be pleasant and free from any off-putting smells.
