What is the "head" of a beer?

1. The alcoholic strength of the beer

2. The foam that forms on top of a beer

3. The flavor profile of the beer

4. The sediment at the bottom of the glass

The correct answer is: The foam that forms on top of a beer

The "head" of a beer refers specifically to the foam that forms on top when the beer is poured. This foam is primarily composed of carbon dioxide that is released from the liquid as it is agitated during pouring. The head plays several important roles in the overall beer-drinking experience. First, it enhances the aroma by trapping volatile compounds, which can significantly affect how the beer is perceived. Additionally, a good head contributes to the visual appeal of the beer, indicating freshness and proper carbonation. A well-formed head can also influence the texture and mouthfeel of the beer, providing a creamy sensation that complements the drink. The head dissipates over time, but its initial presence can indicate the quality of the beer and the effectiveness of the pour. Thus, understanding what constitutes the head and its significance is essential for appreciating the nuances of beer.
