Cicerone Certified Beer Server Practice Exam

What should you look for during a beer bottle examination?

1. Color and aroma of the beer

2. White flakes and gunk at the neck

3. Clarity of the liquid and size of bubbles

4. Label condition and bottle shape

The correct answer is: White flakes and gunk at the neck

When examining a beer bottle, one of the primary concerns is the presence of undesirable substances, such as white flakes or gunk at the neck of the bottle. These can indicate issues with the beer, such as stability or contamination problems. White flakes, for instance, may suggest yeast or protein that has precipitated out, potentially affecting the flavor and overall quality of the beer. This kind of examination is critical for ensuring the product is safe and presents well before consumption. The other aspects to consider—like color, aroma, clarity, and label condition—are also important, but they focus more on the beer's presentation and sensory attributes rather than potential faults. Evaluating the neck of the bottle for any unsettling signs is a precautionary measure for quality control.
