What is one benefit of having a proper head on a beer?

Having a proper head on a beer significantly enhances the drinking experience. The foam created by the head helps to release and concentrate the aromatic compounds in the beer, allowing the drinker to fully appreciate the beer’s aroma and flavor profile. This sensory enhancement can greatly influence how the beer is perceived, including nuances in taste and smell that might otherwise go unnoticed.

In addition to the aromatic benefits, the head also contributes to the overall visual appeal of the beer, adding texture and engaging the drinker’s visual senses. It can create a sense of freshness and quality, which also contributes to the overall perception of the beer.

While a proper head does play roles in other areas, such as potentially affecting the bitterness perception, or even slightly impacting shelf life by creating a barrier to oxidation, the primary and most notable benefit is its enhancement of the drinking experience.
