The head on a beer serves several important functions:
Aroma Enhancement: The frothy foam on top of beer, also known as the head, contributes to the beer’s aroma. As you take a sip, the head releases aromatic compounds, enhancing your overall sensory experience.
Flavor Enhancement: The head isn’t just decorative; it plays a crucial role in flavor perception. By trapping volatile compounds, it helps release flavors more effectively. So, that creamy layer isn’t just for show—it’s part of what makes beer taste great.
Visual Appeal: A well-formed head adds to the beer’s visual appeal. It completes the pouring process and gives the beer a finished look. Different beer styles have specific expectations for the type and thickness of the head.
