What is a potential issue with serving beer in frozen glasses?

1. Enhances flavors of beer

2. Causes foaming

3. Improves clarity

4. Reduces carbonation

The correct answer is: Causes foaming

Serving beer in frozen glasses can indeed lead to excessive foaming when the beer is poured. This is primarily due to the dramatic difference in temperature between the frozen glass and the beer itself. When cold beer comes into contact with the frozen surface, it causes rapid temperature changes, leading to the formation of bubbles. These bubbles can result in an increased amount of foam, which may overflow and create a messy pouring situation while also detracting from the overall drinking experience. The other choices, while they may have their merits in different contexts, do not address the primary concern associated with frozen glasses. Enhancing flavors or improving clarity are not benefits typically associated with frozen glassware. Similarly, while serving beer at too low of a temperature can impact carbonation, this issue does not directly relate to using frozen glasses, which more prominently affects foaming.
