Cicerone Certified Beer Server Practice Test

Which of the following would be acceptable to observe in a bottle of beer that you are about to serve?

1. A light beige/tan yeast residue on the bottom of the bottle

2. A ring of debris around the inside of the neck at the liquid level

3. Haze in a pale lager

4. White flakes swirling in the bottle

The correct answer is: A light beige/tan yeast residue on the bottom of the bottle

It is acceptable to observe a light beige/tan yeast residue at the bottom of the bottle of beer before serving. This indicates that the beer has been fermented properly and may even enhance its flavor. However, options B, C, and D are not desirable or acceptable. A ring of debris around the inside of the neck could indicate contamination or poor cleaning of the bottle, haze in a pale lager could be a sign of spoilage or poor brewing methods, and white flakes swirling in the bottle may also indicate contamination or poor quality ingredients. It is important to properly inspect and assess a bottle of beer before serving it to ensure a quality and enjoyable experience.
