Cicerone Certified Beer Server Practice Test

Question: 1 / 400

If one of the draft lines is pouring foamy, which of the following could be the cause?

Alcohol content of the beer is too high

Bartender is opening the faucet too quickly

Cleaning solution is left in the line

Temperature of keg is too high

Possible Explanation One of the potential causes for a foamy draft line could be a high temperature of the keg. When a keg is stored in a warm environment, the carbon dioxide inside can expand, resulting in excessive foaming when the beer is poured. This option is more likely to cause foamy pours compared to the other options because the temperature of the keg directly affects the carbonation levels in the beer. B and C are also common causes of foamy pours, but they would not solely be the cause of the issue. A higher alcohol content in the beer may contribute to foaming, but it is not a common root cause. Additionally, opening the faucet too quickly may cause some foaming, but it is not as common as the temperature of the keg being too high. Therefore, answer D is the best choice for this scenario.
